Overview
Screw-knob Clamp, 38mm jaws
Why should you invest in a quick-release system? Because screwing your camera or lens onto a platform with standard ¼"-20 screw is tedious and insecure. Not only is it a hassle to screw your gear onto that platform, but once installed the camera or lens is free to rotate; there's nothing to prevent it from coming loose. Why invest your money in a tripod and tripod head only to compromise your shots with an insecure connection between camera and head? Instead, adopt the Really Right Stuff quick-release system.
The Really Right Stuff quick-release system is based on the Arca-Swiss standard and has two parts: a quick-release clamp and a quick-release plate. You always need both pieces of the system. The clamp will stay on your tripod head/accessory all the time, and the plate will stay on your camera all the time. You will need to purchase a separate quick-release plate for each camera or collared, telephoto lens that you want to mount in the quick-release clamp on your tripod head.
Clamp jaws open and close in one of two ways: by twisting a knurled knob on our tried & true screw-knob clamps; or by flipping a single lever on our innovative, patented lever-release clamps. Traditional screw-knob clamps are tried & true and can deliver slightly greater clamping force than our Lever Release clamps.
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.
Features
- 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 can be mounted back to back with our B2-FAB mini-clamp using a flat head screw when you need a double-sided clamp, such as our Mini Clamp Package. 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.

Recommended Uses
- Any platform or accessory with a 1/4"-20 threaded post or stud. The B2-FAB 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). However, these tabs can prevent the clamp from sitting flush on a flat surface.
