Product Description
Overview
The KUPO KCP-0201B Mini Coupler 20 is a black 6061-T6 aluminum coupler for small-tube rigging on 18 to 21 mm outside . It provides compact fixed coupler connection using an M6 x 25 mm bolt and wing nut, giving display, museum, scenic, and architectural installers a properly sized alternative to oversized 2" rigging hardware.
Why It Matters
Using a full-size coupler on small tube looks clumsy and can fit poorly. This mini coupler gives the installer the right contact size, a compact profile, and a rated aluminum body for smaller display and scenic structures.
Key Features

- 6061-T6 extruded aluminum alloy keeps the body light, strong, and corrosion resistant
- Matte black anodized finish helps the coupler disappear into scenery and dark display frames
Applications
Use it for retail displays, museum casework, exhibition booths, small architectural mounts, scenic structures, and lightweight fixtures on compact tube.
Compatibility
Fits 18 to 21 mm outside . It belongs to KUPOs mini coupler family covering small-tube sizes from 20 mm through 40 mm in fixed, swivel, and eye ring formats.
Frequently Asked Questions
Why use a mini coupler instead of a normal 2" coupler?
A mini coupler fits the smaller tube properly and keeps the assembly compact. Full-size couplers are often bulky or poorly matched on display and scenic tube.
Will it fit 20 tube exactly?
Check the outside diameter, not just the name. This SKU is specified for 18 to 21 mm tube, which is the measurement that matters for fit.
Why choose the black version?
Black is the better choice when the hardware should disappear into scenery, black tube, museum casework, or shadow-line installations.
