This DP-505R Dual Axis 50 x 50mm QR Plate from Desmond is a convenient two-pack of Arca-type, RSS compatible quick release plates. Made of machined aluminum, each plate features four rubberized traction pads to resist camera movement and prevent marring camera body finish. The dual-axis design allows turning a camera 90° and remounting in a plate clamp. Each plate includes a 1/4"-20 mounting screw with a D-ring for tightening.
