The CAMVATE Camera Cage Rig with Top Handle, Tripod Plate & Rods is a modular half cage for most DSLRs and mirrorless cameras. It is made from hard anodized aluminum for strength and corrosion resistance. It comes with two different-height side supports, allowing you to adjust the cage's height to best fit your camera. Rubber grip pads on the camera mounting plate provide a tight grip and help prevent your camera from twisting while mounted.
The baseplate mounts onto the tripod mounting plate which features 15mm LWS rod clamps and includes 15mm support rods. The cage not only provides support and protection to your camera but also allows you to use a variety of accessories such as a matte box, follow focus unit, or lens motor. All locking levers are spring-loaded, and the cage abounds with 1/4"-20 and 3/8"-16 threaded accessory mounting holes.
