20 Pack Aluminum Half Conical Coupler with Pins and Clips - Truss Fit

In this review the reviewer looks at a 20 pack of aluminum half conical couplers that target rigging and stage crews who need a reliable set of connectors for truss systems. The bottom line is straightforward: this kit provides a complete set of hardware for quickly connecting half conical fittings to common trussing, and it is most valuable for technicians who want a ready supply of matching bolts and R-clips. The review focuses on fit, included hardware, weight and compatibility so buyers know exactly what to expect.

Key Features

• Complete kit: Each pack includes 20 half conical couplers, 20 M12 bolts and 20 R-clips so crews have matching hardware for multiple connections without scavenging parts.
• Truss compatibility: Designed to fit F31, F32, F33, F34 and F44P trussing models so it covers the common aluminum truss profiles used in live sound and lighting rigs.
• Threaded M12 bolt: The couplers are threaded for M12 bolts which provides a secure fastening method familiar to riggers and stagehands.
• Lightweight construction: Each set is lightweight at about 130 g per piece, keeping added load low while maintaining the strength needed for temporary stage connections.
• Included safety clip: Each bolt ships with an R-clip to prevent accidental disengagement and to speed up setup and teardown operations.

Who It's For

This 20 pack is ideal for small production companies, touring crews and venues that use modular aluminum trussing and need multiple matching couplers at hand. It suits users who prefer to buy a bulk supply to replace lost parts, stock spare connectors or outfit new base and bed plate assemblies.

It is less appropriate for those who need specialized couplers for unusual truss profiles or for permanent welded installations where a different fastening approach would be better. If a single replacement coupler is needed, a full 20 pack may be more than required.

Pros & Cons

Pros

• Includes all hardware needed for each connection so setups are faster and consistent across multiple points.
• Fits a wide range of F-series trussing, making it versatile for live sound and lighting applications.
• Lightweight aluminum construction keeps system weight low while remaining practical for stage use.
• R-clips add a simple safety measure to reduce the chance of bolts backing out during use.

Cons

• Sold only as a 20 pack, which may be more than a hobbyist or single-event user requires.
• Specifications rely on the pictured size reference rather than detailed dimensions in the text, so buyers should confirm fit against their truss before large purchases.

Our Verdict

For production crews and venue technicians who need a reliable supply of matching half conical couplers, this 20 pack is a practical value because it bundles the couplers with M12 bolts and R-clips and fits the common F-series trussing profiles. Buyers who want spare parts or to outfit multiple base plates will appreciate the completeness, while those who need only one or two replacements should consider buying fewer pieces elsewhere.
