Cobalt Cage for GoPro Hero 3/3+/4

Cobalt Cage for GoPro Hero 3/3+/4

SKU: 3-137-0001

Liberate your GoPro Hero 3/3+/4 with the protection and performance of the Cobalt Cage.

Use Excessive Force

Use your GoPro Hero3 or Hero3+ or Hero4* the way it is meant to be used: extreme POV, risky camera setups, insane camera mounts. Make it all happen while keeping your camera secure and your shots rock-solid and stable.

Capture unique images like never before thanks to the reinforced high tensile design of the Cobalt Cage. Unburden your GoPro from the plastic stock GoPro housing and its single point of contact, and expand your capabilities with nearly twenty times the mounting points of the Cobalt Cage. The Cobalt Cage is impact-proof, crash-proof, crush-proof, and bullet proof, all while weighing only 3oz more then the plastic GoPro Housing.

Mount Without Fear

The Cobalt Cage is made of precision-machined military-grade aluminum, and features integrated ¼”-20 threads that surround the camera in 360 degrees. Attach support rails and knuckles directly to the cage to create as many points of contact as necessary. Now, have the ability to mount the GoPro using a true triangulation method, which minimizes vibrations and provides a more stable and secure mounting apparatus to your subject. Expand your arsenal of mounting options with suction cups, Cardellini clamps, speed rail, or mafer clamps.

Free yourself from proprietary, difficult to position, and prone to wear accessories. Under-sling or side-sling the GoPro to achieve perspectives that are otherwise impossible to capture with just the GoPro stock housing.

By giving you the option to bypass the GoPro Housing with the Cobalt Cage’s open-air design, you eliminate fogging that can plague otherwise gorgeous shots, while still keeping the camera and its optics protected.


With 18 industry standard ¼”-20 mounts, not only can you mount your GoPro Hero3/4 to everything, you can mount everything to your GoPro Hero3/4. Add accessories such as LED lights, microphones, or other hot shoe accessories directly to the GoPro and create a self-contained setup ready to move from location to location. By attaching accessories directly to the cage, you minimize the chances of them creeping into frame, and it allows you to fit into even tighter locations. Utilizing articulating ball heads allow for quick and accurate framing, without the need to fiddle with difficult-to tighten-knobs and unreliable joints.

The Only Cage You’ll Ever Need

The Redrock Cobalt cage is simply the best value for the most versatile cage. Nothing compares to the value, incredible features and support the Cobalt cage delivers.

Hero 3/3+/4 supported in Cobalt Cage only as naked GoPro camera (with addition of the deluxe accessory kit) or with the GoPro BacPac Compatible Housing or Original Skeleton housing. PLEASE NOTE: as of July 2014 the Cobalt Cage no longer ships with the finger mount plate.
