Quick release long plate. Gitzo quick release plates come in three different profiles (A, B, and C). Each profile is offered in different lengths (short or square, medium, and long) and with different features (graduated, anti-rotation pin) and attachments (1/4 inch - 3/8 inch). In the new collection, Gitzo unified some 1/4 inch and 3/8 inch attachment plates into a unique new code that includes two screws for both sizes. Having two screws available for each attachment size is ideal, especially for long plates when heavy equipment or long lenses are used. As a general rule, it is preferable to always use the largest possible attachment. In any case, even when the smaller screw needs to be used, it always guarantees a high safety standard. In fact, all Gitzo bolts and screws are made of high-quality steel.
