Quality all metal construction with a low profile design for great Garmin or GoPro footage. The Slim mounts are slimmed down to a basic GoPro adapter and base. Adjust your camera 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. This surface base allows you to turn any two existing fasteners into a secure and stable platform. You can attach your camer to any 2 fasteners 2″-5″ apart such as a wingtip or an inspection cover. A rubber gasket is included to protect your painted surface. Two included flush centering washers fit the base plates slots and accept most #6 – #10 size screws. The surface base has been tested up to 250 kts.
