The KUPO KCP-838B Handcuff Coupler is a black fast-deploy coupler for 48 to 51 mm pipe. Its triggering mechanical design snaps around the tube in one motion, while the 6061 high tensile aluminum body, M12 x 38 mm bolt, and TÜV APPROVED certified 200 kg Working Load Limit support serious overhead fixture work.
Why It Matters
The standard Handcuff Coupler exists because overhead work rewards speed and control. It drops over the pipe, closes quickly, and keeps the wing nut captive, so the rigger spends less time fighting loose hardware above head height.
Key Features
Triggering close mechanism lets the coupler snap around 48 to 51 mm tube quickly
200 kg Working Load Limit gives the clamp a clear rating for professional fixture hangs
Captive wing nut helps prevent loose hardware from falling during overhead installation
Double-level countersunk seat accepts M10 or M12 hex head bolts on the load side
Black anodized finish keeps the coupler low visibility in stage and broadcast rigs
Additional Technical Notes
Dimensions: 105 mm x 120 mm body, 85 mm jaw, 9 mm slot, 19 mm thick
Applications
Use it for heavy luminaires, touring truss, venue grids, rental packages, studio pipe, and fast overhead fixture hangs where a quick-closing coupler saves time.
