The KUPO C-01QB is the quick release version of the C-01B iron casting hook clamp, made for faster fixture changes on 30 to 51 mm tube. A spring-loaded latch holds the 17.5 mm spigot automatically once engaged, while the black iron casting body and 40 kg Working Load Limit suit road-tested stage and TV inventories.
Why It Matters
Quick release hardware matters when fixtures move during focus, changeover, or strike. The C-01QB keeps the durable iron body of the C-01B but removes some of the fiddling from repeated fixture swaps, which is exactly where crews start to notice the difference.

Frequently Asked Questions
Does the latch replace the need to tighten the clamp on the pipe?
No. The quick release latch captures the fixture spigot. The clamp still needs to be properly tightened to the tube before the fixture is considered secure.
When should I choose this over C-01B?
Choose C-01QB when speed matters, especially in rental, focus, or strike workflows. Choose C-01B when a simple standard clamp is enough.
Is the load rating different from the standard version?
No. The specification lists the same 40 kg Working Load Limit for C-01QB and C-01B.
