The SmallRig Tilt Monitor Mount 1842 is designed to attach to a cage or any type of mounting plate that has two 1/4?-20 threaded holes. The mount's two 1/4'-20 screws sit in a slot where they can be moved sideways as needed to match your cage/plate. When you remove the monitor mount, the screws don?t come out, so as soon as you remove it, you can just throw it into your bag; the screws will stay in place. On top, the monitor mount provides a 1/4'-20 mounting screw on a padded platform. And in a simple design, the monitor mount tilts your monitor forward and backward 90° each way with enough tension that nothing needs to be screwed in or tightened. It holds 5 and 7'' monitors up to 3.3 lb in weight. The 1/4''-20 screw on top is secured by a thumbwheel. To tighten the thumbwheel, an Allen key is included that inserts into a slot on the thumbwheel from the front.
