Each AMPS Plate and 20mm Ball Joint Assembly comes with Heavy Duty Bolts and Nylon Locking Nuts so you get everything required for a rock solid installation.
Hole locations are in the standard AMPS pattern of 30mm x 38mm (1.181” x 1.496”) so this will mount to anything with the AMPS hole configuration.
The ball size is 20mm and is compatible with our Carbon Fiber + Kevlar Mounting Arms and our GoPro Mount.
