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.

Use Excessive Force.

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.

Attach the Hero3/4 Camera inside of the Cobalt Cage with the GoPro Housing without needing tools for additional protection from the surrounding elements, or purchase the Deluxe Accessory Bundle to mount the GoPro Hero3 or Hero 3+ or Hero 4 Camera naked within the cage.

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 the 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.
