The NOVOFLEX Q=Plate series QPL-LEVELLER quick release plate fits any Arca-type quick release system (except the Arca Swiss Flip-Lock). This plate features a camera mounting screw (1/4”-20), an integrated bubble level and two slots on a 6.1” long plate, allowing a broad placement of the camera screws relative to the plate or one another. The bottom edges are dovetailed for smoother loading and unloading from the clamp, as well as less abrasions. The screws of the NOVOFLEX plates work with both traditional flathead screwdrivers as well as 5/32" Allen wrenches. Note: The NOVOFLEX Arca-type quick release plates are thinner by the slimmest of margins than Arca-Swiss quick release plates. They are not recommended for use in the Arca-Swiss Flip-Lock quick release clamp.
