Quick Release Plate designed for the B1 & B2 Ball Head.
The PU-60 Arca-Type Quick Release Plate from Benro has a dovetail mount compatible with select Benro heads and other third-party heads and clamps.
Cameras mount to the plate via its 1/4"-20 threaded camera mount, and the anti-twist padding on the top of the plate prevents the camera from moving while mounted to the plate.
