The Dot Line GearBox 2 Accessory Cage is for small cameras and DSLRs and can be handheld or tripod mounted. An adapter holds two 15mm rods at the bottom of the cage and features three 1/4" threads underneath for mounting tripods. The adapter attaches to the bottom by four included screws. The rods are 8" long and female-threaded on both ends for further extension. You can attach a follow focus and matte box onto the rods. The cage itself is made up of a cheese plate on top, one on the bottom, and rubber-grip handles on the sides.
The top plate has fourteen 1/4" accessory mounting threads and nine pass-through holes. The bottom plate has five 1/4" threads and also has a cutout for the battery or memory card door that most cameras have on their bottoms -- accordingly, you won't need to remove your camera from the cage to change a battery or card. On the top surface of this bottom plate, where you would attach your camera, you'll find two non-slip pads that will better support the bottom of the camera. A 1/4" screw with a red knob on one end comes included for attaching the camera. The screw fastens from underneath the cage.
