The KUPO KCP-831ST Half Coupler with Stainless Steel Parts is a stainless coupler for 48 to 51 mm tube. It uses a 50 mm standard body, high tensile 6061 aluminum extrusion, stainless steel fasteners, and a 500 kg Working Load Limit for professional truss and pipe rigging.
Why It Matters
The stainless version is for outdoor, coastal, festival, and industrial environments where ordinary hardware can become the weak point. The aluminum body carries the load while the stainless fasteners resist corrosion in the places that usually seize first.
Key Features
500 kg Working Load Limit supports professional fixture, truss, and pipe-mounted hardware within spec
50 mm standard depth balances tube space and load requirement
Stainless steel fasteners improve corrosion resistance in outdoor and rust-prone environments
48 to 51 mm tube fit matches common 2" stage pipe and truss tube
Stainless finish suits outdoor and corrosion-conscious installs
Use it for outdoor stages, coastal venues, festival structures, industrial sites, and permanent installs where corrosion resistance matters as much as load rating.
Compatibility
Fits 48 to 51 mm tube. Slim versions save tube width; standard KCP-831 versions provide the 500 kg half coupler body; T-handle versions support tool-free tightening.
Frequently Asked Questions
When is the stainless parts version worth specifying?
Use it outdoors, near salt air, in wet festival conditions, or anywhere corrosion could compromise normal fasteners over time.
What tube size does it fit?
It is specified for 48 to 51 mm tube, which covers common 2" stage pipe and truss tube.
Should I choose slim or standard width?
Choose slim for crowded tube space. Choose the standard KCP-831 family when the job calls for the 500 kg rating and the wider body is acceptable.
