Kirk has teamed with ODI, the top manufacturer in the U.S of performance grips, to bring you the Kirk Support Grip Products series. Kirk mounted their quick release clamp on top of a NEW ODI rubberized handle with bottom receptacle, for mounting on 1/4in 20 stud, to create the SG-QR. Kirk's QR Grip can be used with any arca-style camera plate or L-bracket. Kirk's quick release system lets you dismount one camera and secure another in a third of the time of the conventional tripod fingertip screws. Requires a camera plate, lens plate, l-bracket or a long rail plate.
