The KUPO C-08B Aluminum Extrusion Clamp is a high-capacity extruded aluminum clamp for conventional fixtures on 30 to 51 mm tube. It combines interior tube-gripping teeth, a 1/2"-13 yoke bolt, and a 275 kg Working Load Limit in a lightweight body.
Why It Matters
The C-08 family gives crews a lot of rated capacity without the weight of a bulky steel clamp. That makes it useful for conventional fixtures where the clamp needs bite, strength, and fast handling in the same part.
Key Features
High tensile extruded aluminum body keeps weight low while maintaining a positive clamp shape
Interior teeth grip 30 to 51 mm tube to resist slipping under load
275 kg Working Load Limit gives a clear rating envelope for the fixture class
1/2"-13 yoke bolt matches the fixture hardware expected for this clamp size
Black anodized finish helps the clamp disappear in dark truss and TV grids
Additional Technical Notes
Dimensions: 101.5 mm height
Applications
Built for Par cans, fresnels, conventional fixtures, studio lights, and stage grids where a lightweight clamp with a high Working Load Limit is preferred.
Compatibility
Fits 30 to 51 mm tube, 1-1/4" to 2". Uses a 1/2"-13 yoke bolt and washer.
Frequently Asked Questions
Why is the Working Load Limit so high for an aluminum clamp?
The extruded aluminum body is engineered for high tensile strength while keeping weight low. The fixture and rig still need to stay within all applicable safety margins.
Will it fit 2" truss?
Yes, if the tube outside diameter is within the 30 to 51 mm range. That covers many 1-1/4" to 2" tubes.
Why choose the black anodized finish?
Black is better when the clamp is visible to audience or camera, especially in dark truss, TV studios, and theater grids.
