Two Main Truss Connection Systems
When building stage and event structures, the choice between spigot truss and bolt truss can significantly impact your workflow, costs, and structural capabilities. Here’s a comprehensive comparison.
After manufacturing both spigot and bolt truss systems for over a decade, we’ve seen firsthand which applications each type excels in. This comparison draws from real customer feedback and years of field testing.
Spigot Truss: Speed and Convenience
Spigot truss uses a conical connector (spigot) that slides into the chord tube, secured with a pin. This design enables:
- Fast Assembly: Typically 40-60% faster than bolt truss setup
- No Tools Required: Pins and R-clips are all you need
- Lighter Weight: Ideal for mobile DJs and rental companies
- Flexibility: Easy to create custom angles and configurations
Glory Truss offers spigot truss in 100mm, 220mm, 290mm, 400mm, and 520mm sizes to accommodate any event scale.
Bolt Truss: Strength and Stability
Bolt truss connections use high-tensile bolts to join sections, providing superior rigidity:
- Higher Load Capacity: Bolted connections distribute weight more evenly
- Better for Permanent Installations: Once assembled, bolt truss stays rock-solid
- Less Vibration: Ideal for nightclubs and permanent venues
- Larger Spans: Can span greater distances without intermediate support
Cost Comparison
Spigot truss generally costs 10-15% less than equivalent bolt truss, but the real savings come from reduced labor time during setup and teardown. For rental companies doing 100+ events per year, spigot truss can save thousands in labor costs annually.
Our Recommendation
- Rental Companies & Mobile DJs: Spigot Truss
- Permanent Venues & Theaters: Bolt Truss
- Heavy Rigging (LED Walls, Line Arrays): Bolt Truss or 400mm+ Spigot
