The KCP-860B Nugget Coupler is a compact 350 kg Working Load Limit (WLL) clamp for 32-38 mm tube, built for smaller pipe where a full-size 48-51 mm coupler would be oversized. Its 6061-T6 aluminum extrusion body keeps the fitting light in the hand while the captive wing nut and double-level countersunk bolt seat make it practical for daily rigging work.
Why It Matters
Small tube rigs still need serious hardware. This coupler gives scenic shops, display installers, and compact lighting grids a properly rated clamp that does not feel adapted from a larger pipe size.
Key Features
350 kg Working Load Limit (WLL) supports demanding loads on 32-38 mm tube without stepping up to a larger coupler body.
Captive wing nut and safety-wire access windows reduce dropped-hardware anxiety when the clamp is handled above the deck.
Double-level countersunk seat accepts M10 or 3/8" hex hardware, giving the shop useful flexibility with existing bolts.
Applications
A reliable fit for small truss chords, display pipe, compact lighting bars, architectural installations, and specialty frames where 32-38 mm tube is the working standard.
Compatibility
Designed for 32-38 mm tube with an M10 x 38 mm bolt seat and a compact 113 mm overall body length.
Frequently Asked Questions
Is this the right size for 1.25" to 1.5" tube?
Yes. It is made for 32-38 mm tube, which covers the common 1.25" to 1.5" range used on compact frames and specialty pipe.
Why use the Nugget instead of a standard 48-51 mm coupler?
The Nugget is sized around smaller pipe, so the clamp closes properly and keeps the rig cleaner instead of forcing a large coupler onto undersized tube.
Can the bolt hardware be matched to shop stock?
The double-level countersunk seat is designed for M10 or 3/8" hex hardware, which helps when different departments standardize on different fasteners.
