The Kirk PZ-154 Camera Plate for Canon 6D Body with BG-E13 is an Arca-style quick-release plate made of 6061T6 aluminum alloy for the Canon 6D body with the BG-E13 battery grip. The PZ-154 screws into the camera's tripod mount with a stainless steel Allen screw. Two additional Allen screws provide safety stops so the plate can slide across the QR clamp without sliding off.
