Heavy Weight Champ. The Proaim Big Multi-Angle Levelling Wedge Plate guarantees a steady shot with extreme tilt angles for heavier cameras. This plate safely holds up to 44 pounds and features a bubble level to ensure a uniform balance. You’ll find locking mechanisms on both sides that unlock to enable the extreme tilt function up to 90°, and will securely relock at any tilt angle you choose. You’ll mount your camera via the 1/4"-20 and 3/8"-16 screws, but there’s multiple non-threaded mounting points located on this plate.
