The KCP-873B 45 °Coupler is a 500 kg Working Load Limit (WLL) tube-to-tube connector for 48-51 mm pipe, made for repeatable angled geometry rather than free-swiveling adjustment. Its 6061 aluminum extrusion body locks in 45° indexing, giving truss corners, bracing, and custom frames a clean fixed-angle connection.
Why It Matters
Swivels are useful during layout, but a repeat build often needs the angle to land in the same place every time. This coupler gives installers a predictable 45° reference point with less guesswork during load-in.
Key Features
45° indexed adjustment gives repeatable angled connections for bracing and geometric truss details.
500 kg Working Load Limit (WLL) supports serious tube-to-tube work on standard 48-51 mm pipe.
Hex-tool locking helps hold the selected angle after the structure is squared and tightened.
Applications
A strong fit for truss corners, angled support runs, exhibition frames, scenic structures, and fixed bracing details in touring, theater, studio, and installation work.
Compatibility
Designed to connect 48-51 mm tube at fixed 45° increments.
Frequently Asked Questions
Why pick this instead of a swivel coupler?
Use it when the build needs a repeatable 45° angle rather than an infinitely adjustable joint. It is easier to duplicate from show to show.
Does it fit standard truss chord tube?
Yes. It is designed for 48-51 mm tube, the common range used on professional truss and pipe systems.
Can the angle be changed on site?
Yes, the coupler indexes every 45° and locks with a hex tool, so crews can set the required angle during assembly.
