The QUATTUOR is a 4-way leveling Mitchell plate mounted on an 8" x 10" 2020 cheese plate — giving you a low-profile leveling solution at just 2-3/4" total height. The 1" on-center hole pattern accommodates 1-1/4" or 1-1/2" slider brackets, making it a natural fit for Dana Dolly setups and other slider configurations. Anodized flat black, machined aluminum.
