FAQs

What size rail does the large Tough-Claw fit?

Round or square rails and bars from 25mm to 56mm (1" to 2.2") outer diameter, plus flat edges up to 56mm (2.2"). For thinner bars, the medium (RAP-B-404U) or small (RAP-B-400U) claw will hold tighter.

What is the difference between the B and C ball versions?

Same clamp body, different ball. This B version finishes in a 1" ball for B size arms and cradles; the C version (RAP-401U) finishes in a 1.5" ball for C size components. Match the ball to the arm you already run.

Do I need tools to fit it?

No. Place the clamp over the bar and tighten the knob by hand. It comes off just as quickly when you need to move it.
