The KUPO KCP-857 Mighty Swivel Coupler connects one 48 to 51 mm tube to one 51 to 60 mm tube with full 360° swivel movement. Its high-tensile aluminum extrusion body carries a 500 kg WLL for heavy-duty mixed- connections.
Why It Matters
Mixed-diameter structures are common, but fixed couplers can force the geometry before the rig is ready. KCP-857 gives crews angle control between two tube sizes, and the supplied drift pin can lock the assembly into a fixed 90° configuration when that is the correct setup.
