If you're planning a trade show, convention, concert, or festival, there’s one way to guarantee everyone notices you: the Global Truss 20.63’ x 20.63’ x 10’ Circular Dome Booth. This stunning stage truss structure brings architectural elegance and professional-grade strength to your event space — whether it's for a dj truss, lighting truss, or display booth truss.

At Famous Stages, we’ve mastered the art of stage trussing, and today, we’ll guide you step-by-step on how to build this impressive aluminum truss dome system that commands attention and transforms any event.

Materials You’ll Need:

• ✅ 2 pcs. Global Truss SQ-C3-90 Circular Truss
  
• ✅ 8 pcs. Global Truss ST-UJB-12 Universal Junction Blocks
  
• ✅ 4 pcs. Global Truss SQ-4137 Heavy-Duty Base Plates
  
• ✅ 4 pcs. Global Truss F34 Box Truss 4.10 ft. (vertical posts)
  

Step 1: Form the Central Circle of the Dome with Junction Blocks

Let’s start by building the central circular crown of the dome. The Global Truss SQ-C3-90 Circular Truss is composed of four 1/4 Arc segments. But instead of connecting them directly to each other, here’s the trick:

• Insert a ST-UJB-12 Universal Junction Block between each of the 1/4 Arc segments.
  
• Once connected, you’ll form a complete circle, spaced evenly with four ST-UJB-12s positioned at the 12, 3, 6, and 9 o’clock points.
  

This method does two things: it builds a solid circular structure and also preps perfect anchor points for the rest of the dome.

Step 2: Build the Dome Crown — Add the Vertical 1/4 Arc Segments

Next, grab the second SQ-C3-90 Circular Truss, which is also made up of four 1/4 Arc Circles.

• Connect each of these arcs vertically to the ST-UJB-12s you just placed on the central circle.
  
• Once all arcs are installed, you’ll have created a beautiful upward-curving dome that crowns your structure.
  

At this stage, the top dome is complete — compact, symmetrical, and ready for elevation!

Step 3: Assemble the Vertical Posts with Base Plates

Now it’s time to give the dome its height:

1. Attach the 4.10 ft. F34 Box Truss vertical posts to the SQ-4137 Base Plates to provide stable support.
   
2. On top of each vertical post, secure a ST-UJB-12 Universal Junction Block — these will connect to the dome’s base circle shortly.
   

These vertical posts will bring your dome to its full 10-foot towering presence, perfect for any stage truss or convention booth truss setup.

Step 4: Raise and Mount the Dome

Time to lift that masterpiece! Carefully (and with enough hands or proper lifting tools):

• Raise the entire completed dome and align the central circle’s ST-UJB-12s with the ST-UJB-12s atop each vertical post.
  
• Once secured, the Global Truss dome booth stands proudly elevated, with the dome elegantly arching over the event space.
  

Step 5: Customize & Illuminate — Let Creativity Shine

With the dome standing tall, it’s time to make it dazzle:

• Hang lighting truss fixtures, moving heads, or special effects on the circular truss and vertical arcs.
  
• Attach signage, banners, or fabric for brand displays.
  
• For DJs, mount speakers and light effects to create an electrifying dj trussing setup.
  
• For trade shows, use it as a display booth truss to create a dynamic, immersive space that draws crowds.
