How Do I Assemble a Modular 20x20 Exhibit Booth?

A modular 20x20 island arrives as frames, connectors, fabric graphics and accessories, and it becomes a booth only when someone puts it together on the show floor. Good assembly is mostly preparation: knowing what is in each box or crate, who will build it, and in what order the pieces go up. This guide walks through that process so set-up day is calm rather than rushed.

Updated November 2026

This guide answers how do I assemble a modular 20x20 exhibit booth. It covers what the Capital Exhibits product pages say about assembling SEGO, Modco, Cabo and Origami SEG Truss systems, a general step-by-step order, how to install SEG graphics, when to use show labor, and how to pack the booth for next time. Product details below come from each product's own page, and prices were checked in Shopify in November 2026.

Key takeaways

• Assemble a modular 20x20 booth in this order: check the floor plan and parts list, set out the base frames, connect the walls and rooms, install the SEG graphics, connect lighting, then place counters and accessories.
• Always follow the instructions supplied with your display; most of the 20x20 product pages at Capital Exhibits list instructions among their downloads.
• SEGO and Origami SEG Truss are listed as tool-free, and Modco uses tool-free pin-lock connectors, but the Origami islands recommend a ladder for setup.
• Modco and Cabo 20x20 booths ship by LTL freight in crates, so plan for unloading and, where needed, a show labor crew.
• Check your exhibitor manual for rules on who may assemble booths, height limits, electrical orders and hanging signs before the show.

How Do I Assemble a Modular 20x20 Exhibit Booth?

To assemble a modular 20x20 exhibit booth, unpack and check every part against the parts list, mark the booth layout on the floor, connect the frames into walls and rooms using the system's connectors, then install the fabric graphics, connect any lighting and place counters and accessories. Follow the instructions supplied with your display, and use a show labor crew if the booth is crated, very tall or the venue requires it.

1. Read the instructions and floor plan before the show.
2. Check the parts list against what arrived.
3. Build the frames from the floor up.
4. Install the graphics.
5. Connect lighting and power.
6. Place counters, towers and accessories.
7. Walk all four sides and fix gaps or wrinkles.

1. What the Product Pages Say About Assembly

Each modular system describes its own assembly method on its product page. Start here, because it tells you whether you need tools, a ladder or a freight dock.

Most of the 20x20 product pages also list downloads such as instructions and spec sheets, and the Origami pages add product training. If a page does not list instructions, ask Capital Exhibits for them. Read them before the show, not on the floor.

2. Before the Show: Preparation Checklist

Most assembly problems start before the booth leaves your building. A short preparation routine prevents missing parts and wasted time on set-up day.

• Read the instructions from the product page and keep a printed copy with the booth.
• Check the parts list. The Modco 11 page, for example, lists each frame size, connector type, cover profiles and frame protectors. Count them the first time you unpack.
• Label everything. Mark crates, boxes and bags with what is inside and where it goes in the booth.
• Bring a floor plan. Show where each wall, room, counter and tower sits, and which way each graphic faces.
• Read the exhibitor manual for move-in times, labor rules, height limits and electrical deadlines.
• Order services early: electrical for lit booths, and labor or rigging if you need it.
• Pack a small kit: gloves, a step ladder if allowed, cleaning cloths and a lint roller for fabric.

For a wider show-planning list, see the Trade Show Exhibitor Checklist.

3. Should Your Team or Show Labor Assemble It?

Your own team can often assemble a tool-free modular booth, but a 20x20 is a large structure, and some systems or venues call for a show labor crew. Decide this before you travel.

If you hire a crew, send them the instructions, parts list and floor plan in advance. For how freight and setup fit into the buying decision, see the freight and setup section of Where Can I Buy 20x20 Trade Show Displays?

4. Step-by-Step Assembly Order

The exact sequence depends on your system's instructions, but most modular 20x20 booths go up in the same general order: floor plan, base frames, walls and rooms, upper structure, graphics, lighting, then furnishings.

Step 1: Mark the layout

Confirm your booth boundaries and orientation to the aisles. Lay out where each wall, room and counter will stand, keeping the 20ft x 20ft footprint in mind.

Step 2: Unpack in order

Open crates and boxes in the order you will need the parts, and keep graphics in their bags until the frames are standing so they stay clean.

Step 3: Build the base frames

Assemble the lowest frames and feet first. With Modco, frames join with pin connectors; with SEGO, components connect without tools; with Origami, the folding truss is listed as tool-free.

Step 4: Add walls, rooms and doors

Connect the wall frames and any storage room. The SEGO Configuration I includes a door hinge for its room, and the Modco 11 includes a door set with lock.

Step 5: Add the upper structure

Add towers, headers, canopies or bridges last, once the base is stable. Use the recommended ladder for tall truss work.

Step 6: Check alignment

Before graphics go on, check that frames are square and connections are fully seated. Fixing alignment now is easier than after the fabric is installed.

5. Installing SEG Fabric Graphics

All four 20x20 systems use SEG fabric graphics, which have a silicone edge that fits into a channel in the frame. The Cabo pages describe 12mm x 3mm silicone beading sewn around each panel for easy installation and removal, hidden from view once installed.

• Match each graphic to its frame using your floor plan and any labels. Graphics for different frame sizes are not interchangeable.
• Follow the instructions for your system, working the silicone edge into the channel evenly around the panel so the fabric sits smoothly.
• Check orientation before you finish: logos and text should face the aisle they were designed for.
• Install blockout panels where supplied. The SEGO Configuration I includes 6 unprinted blockout panels for the inside of the room.
• Know which side is printed. The Origami Island - D is single-sided, and the back of each panel shows the black fabric backing.

Handle fabric with clean hands and keep it off the floor. For artwork that fits correctly in the first place, follow the Graphic Specifications and Artwork Setup Guide.

6. Connecting Lighting and Power

Connect lighting after the graphics are installed and before you place furniture, so you can see how the booth looks lit. Make sure the electrical service you ordered from the show is in the right place.

• SEGO: UL-certified LED lighting is built into the aluminum frame profiles and powered through magnetic electrical connections, so there is no exposed wiring. Configuration I lists 5 SEGO-5MWIRE pieces in its parts list.
• Origami Island - D: includes 10 LED front lights with lamp bases.
• Modco: spotlights are sold separately, such as the Modco LED Spotlight 6.5W ($218).

Plan cable routes so cords stay inside rooms or behind walls, and confirm the location of your power drop with the show before move-in. For other illuminated options, browse Trade Show Backlit Displays.

7. System-Specific Assembly Notes

Each system has its own connectors and quirks. Use these notes alongside the instructions for your configuration.

SEGO

Toolless frames and magnetic electrical connections make SEGO the simplest 20x20 to handle, and it ships in boxes with a foam-cut carry bag. Keep track of the inline and straight connectors (the Configuration I lists 8 SEGO-ILCON and 14 SEGO-SCON), since small parts are the easiest to lose.

Modco

Modco uses multiple frame sizes joined with toolless pin connectors, plus clip connectors and cover profiles. The Modco 11 parts list includes 96 frame protectors, so keep them on the frames during handling. Spare parts, such as the Modco Pin Connector ($34), are sold in Modco Parts and Accessories.

Cabo

Cabo is an aluminum extrusion profile system with a silver anodized finish, in 40mm and 80mm profiles. It ships by LTL freight only, in a crate, so plan for unloading equipment at the venue.

Origami SEG Truss

The 6in x 6in folding truss is listed as tool-free, with a tall ladder recommended for the Island - D. It is rated for indoor use only. Browse the full range in Trade Show Truss Displays.

8. Adding Counters, Towers and Hanging Signs

Place freestanding pieces after the main structure is lit and checked, so you can see sightlines from every aisle. Keep walkways clear around all four sides.

• Counters: the ONE CHOICE Gopher Pop Up Counter ($429) sets up without tools and is included in the Origami Island - D package. More options are in Trade Show Counters.
• Towers: the EZ Tube Tower 4ft x 16ft x 4ft ($1,970) uses 30mm aluminum tubing with push-button, tool-free connections, a pillowcase graphic that zips at the bottom and a travel bag. It is for indoor use.
• Hanging signs: browse Trade Show Hanging Banners. Hanging signs need rigging from the venue ceiling, so check your exhibitor manual for who installs them and when.

9. Teardown and Packing for the Next Show

Take the booth down in roughly the reverse order you built it: accessories, lighting, graphics, upper structure, walls, then base frames. Packing carefully is what makes the next assembly fast.

• Remove and bag graphics first, before frames come apart, so fabric stays clean.
• Disconnect lighting before removing any frame that carries it.
• Count small parts (connectors, pins, clips) back into labeled bags.
• Repack into the original bags, boxes or crate in the same order, following the instructions.
• Note any damaged or missing part right away and order a replacement before the next show.

10. Common Assembly Mistakes to Avoid

Most set-up delays come from a few avoidable mistakes. Check these off before you leave for the show.

Frequently Asked Questions

How do I assemble a modular 20x20 exhibit booth?

Check the parts list, mark the layout, build the base frames, connect walls and rooms, add the upper structure, install the SEG graphics, connect lighting and then place counters and accessories. Always follow the instructions supplied with your display.

Do I need tools to assemble a 20x20 modular booth?

The SEGO and Origami SEG Truss product pages list tool-free assembly, and Modco uses tool-free pin-lock connectors. The Origami islands recommend a ladder, so check each product page for what it calls for.

Can my own team set up a 20x20 booth?

Often yes, especially with a box-shipped, tool-free system like SEGO, if the venue allows exhibitor labor. Crated systems, tall truss and venues with labor rules may call for a show labor crew; the Origami SEG Truss Inline - A product page recommends show site labor.

Where do I find assembly instructions?

Most of the 20x20 product pages at Capital Exhibits list instructions and spec sheets among their downloads, and the Origami pages also list product training. Download them before the show, and ask Capital Exhibits if a page does not list them.

How are SEG graphics installed?

SEG graphics have a silicone edge sewn around each panel that presses into a channel in the frame. Follow your system instructions, work around the panel evenly, check orientation, and install any blockout panels supplied.

How do I power a backlit 20x20 booth?

Order electrical service from the show and plan where the power drop will be. The SEGO system uses LED lighting built into the frame with magnetic electrical connections, so connect it after the graphics are installed.

Who installs a hanging sign over a 20x20 booth?

Hanging signs need rigging from the venue ceiling. Check your exhibitor manual for who installs them, the deadlines and the rules for your booth.

Final Thoughts: Prepare Before You Build

A modular 20x20 booth is designed to go up from standard parts, and most systems need few or no tools. The difference between a smooth set-up and a stressful one is preparation: read the instructions, check the parts, plan labor and power, and pack carefully for next time.
