Kupo Super Knuckle Square AMPS Mounting Plate

Part of a modular system that uses a shell that accepts two ball joints, the Super Knuckle Square AMPS Mounting Plate from Kupo features a ball that fits in one side of the knuckle and allows it to rotate 360 degrees, while holding an accessory with its opposing side. The plate beneath the ball has seven holes to attach it to walls or apple boxes with nails or screws.
