Get the perfect shot from your action camera when you're out on the water with the Tough-Pole. This kit consists of a 1.5" Track Ball™ with a short double socket arm, 12" PVC pipe, B size short arm at the top and a universal action camera adapter. The various ball and socket components allow you to adjust your mount at virtually any angle, and offer the ability to collapse and stow away when not in use. Any action camera with a two-pronged attachment (including GoPro) will work with the action camera adapter, and the Track Ball will connect to any track mounting system including the RAM Tough-Track. The T-bolt is 0.48" by 0.95"
