This Anti-Twist Cold Shoe Mount Support two-pack from SmallRig is designed for camera cages, top handles, and other supports that offer a 1/4"-20 thread. Two shoe mounts are included for expanding your rig to support additional accessories. The shoe mounts feature the same threaded holes and matching screws are supplied to attach them to your rig.
Arrow markers on each one indicate which side your accessory should be mounted from. Each mount also includes a removable positioning pin to prevent the mounts from twisting, and it can be stored in the thread on the side when not in use. Silicone padding on the bottom prevents the mount from scratching your gear and prevents slipping.
