GoPro Slim Clamp Mount: Adjust your GoPro by rotating the aluminum adapter 360 degrees on a 1/4-20 threaded stud. Lock in place with the jamb nut using a 7/16" wrench. With the clamp base you can mount your camera to any frame, round tubing, handle, or gear leg. This all metal base clamps around any tubing 1/2" - 1" diameter. Includes thumb screws with hex drives to be installed by hand or with a hex wrench. The aluminum block has countless configurations, such as with a U-bolt clamp for installs with tight clearances, with longer bolts for wide reaches, or simply bolted to a flat surface. It is recommended to use the GoPro safe metal case to eliminate the common problem of plastic cases and mounts breaking.
