The Velbon QB-635L Quick Release Plate fits the QRA-635 and QRA-667 quick release systems, and the PH-163Q, 173Q, 263, PHD-51Q, 61Q, and QHD-61Q tripod heads. This plate features a long platform with adjustable 1/4"-20 camera screw and two pop-up anti-twist pins.
A quick release plate can be kept attached to the camera's base and allows the user to quickly and easily attach or remove the camera from the tripod without having to waste time fumbling with the threaded mount.
Two pop-up anti-twist pins help the camera to stay in place on the plate.
