Mini-clamp with ¼"-20 threaded socket and anti-twist tabs, 38mm jaws. The B2-FAB mini-clamp has one 1/4"-20 threaded socket for screwing onto a 1/4"-20 threaded post or stud. It has two small tabs that extend from the bottom that can drop into a slot to prevent the clamp from twisting when mounted on a rail or back to back with another of our clamps (such as B2-mAS).
Made for minimal clearance and minimal weight and compact size, the knob of the B2-FAB mini clamp bears directly against the clamp jaw and is "captive" – can't be lost in the field.
Need a sliding clamp platform? The B2-mAS (as in mini-AS clamp) can be mounted with a flat head screw back to back with our B2-FAB mini-clamp when you need a double-sided clamp (as when using our camera bars). The tabs on the bottom of the B2-FAB allow it mount in the recessed "cross" on the bottom of the B2-mAS without twisting.
