Product Description
Overview
The KUPO KCP-0401 Mini Coupler 40 is a silver small-tube coupler machined from 6061-T6 extruded aluminum alloy. Sized for 38 to 41 mm outside , it provides M10 x 30 mm bolt and wing nut for a compact fixed tube connection, giving display, scenic, museum, and architectural installers a clean alternative to oversized 2" rigging hardware.
Why It Matters
A fixed mini coupler keeps small-tube rigging compact and properly matched to the pipe. It avoids the bulky look and poor seating that can happen when a full-size coupler is forced onto display tube.
Key Features
- 38 to 41 mm feasible tube size matches the 40 small-tube range instead of oversized 2" hardware
- 100 kg Working Load Limit gives installers a defined rating for lightweight rigging tasks
- M10 x 30 mm bolt and wing nut provides the specific connection style for this coupler format
- 6061-T6 extruded aluminum alloy keeps the body light, strong, and corrosion resistant
- Polished aluminum finish keeps exposed display rigging clean and easy to identify
Applications
Use it for retail displays, exhibition booths, museum casework, shop lighting, compact scenic builds, and architectural mounts using smaller-than-standard tube.
Compatibility
Fits 38 to 41 mm outside . It belongs to KUPOs mini coupler system covering 20 mm through 40 mm small-tube sizes in fixed, swivel, and eye ring formats.
Frequently Asked Questions
Why not use a regular coupler here?
A regular coupler is physically larger and may not seat properly on small tube. This part is sized for the actual tube range, so the contact is cleaner.
Will it fit a 40 mm tube exactly?
Check the actual outside diameter. This SKU is specified for 38 to 41 mm tube, and that range is the fit standard to use when ordering.
Why pick the silver finish?
Silver is useful for exposed industrial-looking displays, shop inventory visibility, and rigs where the hardware does not need to hide.
