Professional truss and rigging guide
Spigoted vs Bolted Truss Connections.
How conical spigots, pins and bolt-together connections differ—and why compatible truss systems must never be mixed by appearance.
Plain-language definition
Understand the role before selecting equipment.
Professional truss series use connection systems defined by their manufacturer. Conical couplers or spigots and bolt-based systems have different components, assembly details and inspection points.
This page explains the setup logic so organisers, agencies, venues and production suppliers can exchange a complete brief. It is educational guidance—not a capacity chart, installation instruction or approval for a real structure.
The practical decision
What must be resolved.
Identify the exact manufacturer and series before choosing couplers, pins, clips, bolts, nuts, washers or corners. Dimensions that look similar do not prove compatibility.
Names used in rental catalogues are useful for discovery, but the exact model, connection path, installation method and responsibility still need to be written into the project scope.

What a useful technical brief contains.
Always identify
- Exact equipment and manufacturer series where applicable
- Verified weights, dimensions and operating positions
- Support, suspension and complete load path
- Venue or site rules and current technical drawings
- Access, lifting, work-at-height and exclusion zones
- Installation, inspection, show and dismantling responsibilities
Setup process
Eight checks from brief to handover.
01Define the event and technical outcome
02Obtain the venue or site information
03Identify the exact compatible system
04Verify equipment data and positions
05Map supports, suspension and clearances
06Agree lifting, access and build sequence
07Record responsibility and change control
08Inspect and hand over the completed setup
How CK approaches it
Truss expertise in the context of the full event.
The structure is coordinated with the stage, LED, lighting, sound, branding, scenic surfaces, guest routes, venue access and operating schedule.
Real inputs
Start with dimensions, equipment, weights, positions and site facts.
Supplier scopes
Define who supplies, installs, connects, operates, inspects and removes each element.
Build sequence
Plan crew, transport, lifting access, exclusion zones, testing and rehearsal.
Controlled changes
Inspect the final setup and review any later equipment or surface change.
Technical boundary
A guide explains; the project team approves.
Never improvise connector hardware, force misaligned joints or combine unrelated truss series. The complete assembled system follows the relevant manufacturer information.
Published equipment ratings apply only under their stated conditions. The assembled structure, supported loads, geometry, connections, venue or ground, environmental effects and operating method must be considered together.

Spigoted vs Bolted Truss Connections questions.
What does spigoted vs bolted truss connections mean in event production?
Professional truss series use connection systems defined by their manufacturer. Conical couplers or spigots and bolt-based systems have different components, assembly details and inspection points.
What information should I provide about spigoted vs bolted truss connections?
Manufacturer, model or series, section photos and identification, connection components, erection orientation, missing or replacement hardware and any damage history.
Can the final rigging arrangement be selected from this page?
No. Never improvise connector hardware, force misaligned joints or combine unrelated truss series. The complete assembled system follows the relevant manufacturer information. The final method follows the exact equipment, manufacturer information, venue or site conditions and assigned competent people.
Who confirms the final truss and rigging method?
Responsibility depends on the project, venue and contract. The supplier, production team, venue or local rigger, competent inspector and engineer where required must have their scopes and approval route identified before installation.
