Global TrussSQ4121 0.5 M 2-Way 90-Degree Corner Truss
Independent shopping perspective
The Korena take
A 90-degree two-way corner block with 0.5 m legs. Use it to turn a Global Truss square run into a corner or goalpost.
Strong match
Who this is for
- Turning a horizontal truss run 90 degrees at a stage corner
- Building the top corners of a ground-supported goalpost
- Joining an upright to a horizontal span in a square layout
Consider the trade-offs
When to look elsewhere
- Runs that need three- or four-way junctions
- Anyone needing an angle other than 90 degrees
- Mixing with triangle truss or non-SQ4 square truss
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
11-7/16 in. cross-section width
Sets the truss profile. Anything you connect it to must share this width or it won't line up.
Detail 03
3/4 in. diagonal bracing
The internal webbing that resists twisting. Heavier bracing means less flex over long spans.
Detail 04
0.5 m legs on each side
The corner adds half a meter in each direction. Factor that into your overall span math.
Detail 05
2-way, 90 degrees
Two openings only. Adding a third direction at the same point requires a different corner block.
Detail 06
15 unit weight
Heavy for its size because of the steel. Two people is easier for overhead assembly.
Final check
Know before you order
- 01Connection hardware, straight sections, and base plates are separate purchases
- 02The 0.5 m legs count toward your total run length — measure before ordering
- 03Confirm your existing truss shares the 11-7/16 in. profile
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01How many corners do I need for a goalpost?
Two — one at each top corner, joining the uprights to the horizontal span. Four-sided structures need four.
02What size clamps fit this?
Clamps sized for a 2 in. tube, which is the outer diameter of the main chords here.
03Does it come with connection hardware?
Plan on hardware as a separate purchase and confirm it matches the SQ4 series before your assembly date.
04Can I use it with truss from another brand?
Not reliably. The 11-7/16 in. width and connection point spacing have to match exactly, and that varies by brand and series.
