The KUPO C-01B Steel Iron Casting Clamp is a black hook clamp for 30 to 51 mm tube, built for crews who want the familiar C-05 style geometry in a heavier-duty iron casting body. It carries a 40 kg Working Load Limit, weighs 640 g, and uses a 3/8"-16 yoke bolt for fixture attachment.
Why It Matters
Some clamps live in rental stock for years of fast hangs, hard strikes, and imperfect storage. The C-01B is aimed at that kind of service life: stronger body material than an aluminum hook clamp, a subdued black finish, and a simple bolt connection that crews already understand.

Frequently Asked Questions
How is this different from the quick release C-01QB?
The C-01B is the standard bolt version. Choose it when you want a simple fixed yoke-bolt clamp; choose C-01QB when fixtures are changed often and the spring latch saves time.
Will it fit standard 2" tube?
Yes. Its 30 to 51 mm range covers common 2" tube and many lighting bars, provided the tube is within the specified outside diameter.
Why choose iron casting instead of aluminum?
Iron casting is heavier, but it gives the clamp a more durable feel for repeated road use and rental inventory handling.
