60mm Screw-Knob Pro Clamp | B2-Pro-II
Overview
The B2-PRO II by Really Right Stuff is a screw-knob clamp, with 60mm jaws. It features an integrated spirit level, as well as laser engraved scale markings for mounting your Really Right Stuff or Arca-Swiss style quick release plate. The clamp jaws open and close by twisting an ergonomic knurled knob and deliver slightly greater clamping force than our Lever Release clamps.
This clamp has a threaded 3/8"-16 center socket with countersink; as well as two countersunk holes spaced at 30mm apart to attach to our PG-02 or FH-02 gimbal heads, MPR rails, and some legacy ballheads such as the FOBA Superball ballhead.
Why should you invest in a quick-release system? Because screwing your camera or lens onto a platform with standard 1/4"-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. Our RRS traditional screw-knob clamps are put through rigorous testing and can deliver slightly greater clamping force than our Lever Release clamps
