Install a Golf Simulator Enclosure: The Right Way

How do you install a golf simulator enclosure? Installing a golf simulator enclosure takes 45 minutes to 4 hours depending on the kit. The process has seven steps: prepare the space with exact measurements, assemble the base frame on the floor, stand the vertical posts (two people required), attach the top frame and check it is square, mount the impact screen starting from the bottom bungees, add side netting for shank protection, and install edge padding for safety. The most common mistake is an out-of-square frame that prevents proper screen tension. A SIG10 kit requires no tools. A Carl’s Place DIY or custom EMT build requires a hacksaw, drill, tape measure, and level.

The enclosure is the most intimidating part of building a golf simulator.

You look at photos of these aluminum and conduit structures and they look like something from a construction site. Then you open the box and find brackets, pipes, bungees, and a folded screen that weighs as much as a small adult. It is natural to assume this is going to be a nightmare.

It is not. An enclosure is a rectangular box with fabric stretched across the front. That is all it is. The parts are designed to go together in a specific order, and if you follow that order, you will be hitting balls within two hours.

This guide walks you through every step for the three most common enclosure types — the SIG10, the Carl’s Place DIY kit, and a full custom EMT conduit build — so you know exactly what to expect before you start.

What You Will Need

The tools depend on which enclosure you bought.

For a SIG10 or similar prefab kit: Nothing. The frame uses aluminum connector rods and tension joints. No cutting, no drilling, no hardware. You need a step ladder for the top section and a friend to hold the vertical posts.

For a Carl’s Place DIY kit or any build that uses EMT conduit: Hacksaw or pipe cutter. Tape measure. Level. Drill with a 1/8-inch bit (for the corner brackets). Rubber mallet. Step ladder. File or sandpaper for deburring the cut ends of the conduit — this matters more than you think because sharp edges will cut the screen the first time a ball hits it at 80 miles per hour.

For a full custom EMT build: Everything above plus a conduit bender if you need 90-degree bends for a ceiling-mounted frame, a rivet gun if you prefer rivets to screws, and a stud finder for wall-mounted brackets.

Regardless of the kit, set aside a clear floor area about twice the size of your enclosure. You will be laying parts out, assembling sections on the floor, and standing the whole thing up.

Step 1: Prepare Your Space

Clear the room completely. Move everything out. You need access to all four walls and the ceiling area where the enclosure will sit.

Mark the floor. Measure from the back wall to the front of the enclosure position. Most enclosures need 6 to 12 inches of clearance behind the screen for ball bounce-back. Mark the four corners of the base with tape. Check that your enclosure fits in the width with 6 inches of clearance on each side for the side netting.

Check the ceiling height. If you are mounting a ceiling-braced frame, you need to confirm the ceiling is high enough. Stand in the hitting position, take a practice swing, and make sure you have at least 6 inches of clearance at the top of your backswing. If you hit the ceiling during a practice swing, you will hit the enclosure frame during a real swing.

Locate your power and data runs. If you are running cables through the enclosure frame, do it before you assemble the frame. Running cables after assembly means zip-tying them to the outside, which looks sloppy and creates snag hazards.

Step 2: Assemble the Base Frame

This step happens on the floor. Do not stand any vertical posts until the base is fully assembled and square.

For a SIG10: Lay out the base rails and connect them with the aluminum corner joints. They click together. Push each joint until it seats fully — partial connections create wobble. Lay the assembled base flat on the floor where your marks indicate.

For a Carl’s Place DIY or custom EMT: Cut your base rails to length. Use a pipe cutter if you have one — it makes a cleaner cut than a hacksaw. Deburr every cut end with a file. A jagged edge will tear through side netting the first time you hit a shank. Dry-fit all pieces before tightening anything so you can adjust.

Check square. This is the most important measurement of the entire build. Measure diagonally from the front-left corner to the back-right corner. Then measure from the front-right to the back-left. The two numbers must match within 1/4 inch. If they do not, shift the frame until they do. An enclosure that is not square will never tension properly, and you will spend hours chasing wrinkles that cannot be fixed.

Step 3: Stand the Vertical Posts

This is where you need a second person. Do not attempt this step alone.

For a SIG10: Slot each vertical post into the base corner joint. Your partner holds the post upright while you attach the next one. Do all four posts loosely first, then tighten. If you tighten each post as you go, the last one will not align with the base.

For EMT conduit: Insert each vertical into the base corner bracket and secure with the included hardware. Start all four posts, finger-tighten the connectors, then do a full tighten once all four are standing. Use a level on each post to confirm it is plumb. A post leaning 1/4 inch at the base becomes a 1-inch lean at the top, and you will see it every time you look at the enclosure.

Step 4: Attach the Top Frame

The top frame is the most awkward piece because you are working above your head. Your partner holds one side while you attach the other.

For a SIG10: Lift the top frame section and connect it to the vertical posts using the same click-joint system. Work from corner to corner, not side to side. Tighten after all four corners are connected.

For EMT conduit: The top frame is usually two or four sections that connect in the middle. Install each section working from one corner across. Use a step ladder. Do not over-tighten the center connectors until the frame is fully squared.

Re-check square at the top. Measure diagonally from top-left to bottom-right and top-right to bottom-left across the full frame. If the top is off, loosen the vertical post connectors, square the frame at the top, and re-tighten. This catches the twist that happens when you assemble from the base first.

Step 5: Mount the Impact Screen

The screen is the most expensive part of the enclosure, and it is surprisingly heavy. Lay it out on a clean floor or tarp before attaching. Make sure the printed side faces the hitting area.

Bungee systems (SIG10, most prefab kits): Start with the bottom bungee anchors. Work from one side to the other, attaching each bungee at a 45-degree angle. Hook them loosely at first. After all bottom bungees are hooked, go back and tension them evenly. Work left to right, adding 1/4 turn of tension to each. Then move to the top, then the sides.

The 45-degree angle matters. If you hook bungees straight across, the screen will sag in the center over time. The crossing pattern creates a net effect that distributes tension across the full surface. This is the difference between a screen that stays tight for two years and one that goes baggy in six months.

Velcro systems (Carl’s Place, some budget kits): Start at the center. Attach the center of the screen to the center of the top frame. Work outward to the corners, smoothing as you go. A helper on the other side keeps the screen from sagging. Press the velcro firmly along the full strip of each connection point. Tacking it only at the edges leaves gaps that let balls escape. A velcro strip with gaps at the top will let a ball wedge through on a high shot, and you will find out exactly how fast you can sprint to catch a golf ball before it hits your TV.

Tension test. Drop a golf ball from shoulder height onto the center of the screen. It should bounce back 2 to 3 feet. If it thuds and drops, the screen is too loose. If it sounds like a drum and the ball rockets back at you, it is too tight — back off the tension slightly. The right tension sounds like a soft thump.

Step 6: Add Side Netting

Side netting catches the shanks and heel strikes that miss the screen by 2 feet. Every enclosure comes with it. Most people install it backward.

The netting goes on the inside of the frame, not the outside. If you mount it on the outside, a ball that hits the net will push through and hit the wall behind it. Mounted on the inside, the net deflects the ball back toward the center of the enclosure.

Attach the netting to the side frame using the included bungees or clips. Start at the top, work down, and leave the bottom loose enough that a ball hitting low will deflect rather than funnel toward the floor. A rigidly tensioned side net will guide balls into the gap between the net and the screen. A slightly loose net absorbs and drops them.

Step 7: Install Edge Padding and Finish

Edge padding wraps around the frame to protect the screen and your walls. It also protects you — the corner joints of an EMT frame are hard enough to hurt.

Frame padding: Wrap the foam padding around the front edge of the frame, covering the connector joints. Secure with velcro straps or zip ties. Make sure the padding extends past the corners by at least 2 inches on each side for full coverage.

Floor protection: If your enclosure sits on a hard floor, lay down a 4x4 or 4x6 foot turf mat under the hitting area. This protects the floor from club strikes during practice swings and gives the mat something to grip rather than sliding across concrete or wood.

Final stability check. Push on the top of the enclosure from the hitting side. If it rocks forward, the base is not weighted. Add sandbags or weight plates to the back base rails. A 150-pound person swinging a driver generates enough force to tip an unweighted enclosure forward. You do not want to discover this on your first swing.

Kit-Specific Installation Notes

SIG10 (45-60 minutes): The easiest install by a wide margin. Everything clicks together. No cutting, no measuring beyond the initial room dimensions. The bungee tensioning system is forgiving — you can re-tension the screen after a month when the fabric settles. Many SIG10 installs are done in one evening including the mat and projector setup.

Carl’s Place DIY (2-3 hours): The EMT conduit needs cutting to your exact room dimensions. Measure twice, cut once. The most common issue is cutting the horizontal rails too short because you forgot to account for the corner bracket depth. The brackets add 2 inches to each connection. Subtract that from your rail measurements.

Custom EMT build (4-6 hours): You are sourcing 1-inch or 3/4-inch EMT conduit from Home Depot, cutting it yourself, and assembling with set-screw connectors. The process is the same as the Carl’s Place kit, but you need to buy the connectors separately and verify compatibility. Use 1-inch conduit for a 10x8 enclosure. Anything smaller flexes when a ball hits the screen and the wobble shakes the projector image.

Common Installation Mistakes

Frame out of square. This is the number one mistake and it causes every other problem. If the frame is not square, the screen will never tension evenly, the projector image will not align, and gaps will open at the corners. Measure diagonal twice during assembly — once on the base, once after the top frame is attached.

Skipping deburring on cut conduit. A single sharp edge on a cut EMT pipe will cut through side netting or the impact screen on the first high-speed ball strike. File every cut end until it is smooth enough to run a finger across without snagging.

Mounting the screen before tensioning the frame. Some people attach the screen to an untensioned frame, then try to square the frame with the screen on. The screen weight pulls the frame out of square immediately. Square the frame, lock it down, then add the screen.

Tightening all fasteners during dry-fit. Leave everything finger-tight until the full frame is assembled. Tightening as you go traps misalignment in the frame. You want the ability to shift the frame while squaring it.

Forgetting bounce-back clearance. The ball hits the screen and bounces back 2 to 6 feet. If the back of your enclosure is against a wall, install a net behind the screen or leave 12 inches of clearance. Balls that hit a wall behind a screen and bounce back create double-impact marks and eventually tear the screen material.

Final Tensioning Check

After 30 days, re-check screen tension. New screens settle as the fabric stretches under impact. A screen that was tight on day one will have 1/2 inch of sag after 50 balls. Re-tension by tightening each bungee or velcro strip by one notch. Do this monthly for the first three months, then quarterly afterward.

A properly tensioned enclosure frame should last 5 to 10 years with normal use. The screen is the consumable part — expect to replace it after 2 to 3 years of regular hitting, or sooner if you hit it with a wedge from 3 feet away. The frame itself is a one-time purchase.

You Can Do This in One Weekend

The enclosure installation is the heaviest part of a sim build, but it is also the most straightforward. You measure the space, you assemble the frame, you hang the screen, and that is the enclosure done. The rest of the setup — launch monitor positioning, projector mounting, mat placement — is easier because you are working with smaller, lighter components that sit on the floor.

Set aside a Saturday. Invite a friend. Buy pizza. The enclosure is the part that looks like a real simulator when it is done, and seeing that frame standing in your garage is the moment the whole thing becomes real.
