Stainless Steel Half Coupler

Made from high-strength 6061-T6 aluminum alloy with a lightweight extruded body, the KUPO KCP-831ST 2" Stainless Steel Half Coupler is engineered for both performance and durability. All fixing parts—including the M10 countersunk head screw and anti-slip nylon locknut—are made of stainless steel, ensuring excellent corrosion resistance for long-term outdoor use. The coupler supports loads up to 500kg (WLL2) while weighing only 520g, and fits pipe diameters from 48mm to 51mm. A unique broken-tooth feature at the end of the screw prevents the hex nut from loosening, while the smooth, curved inner wall helps protect truss surfaces from scratches.
