EZ4 and EZ5 brackets have a clean, uncluttered look, whether you're towing or driving. A spring-loaded locking system allows the brackets to be recessed even farther than earlier models. Both locks 'click' as each of the front arms are rotated into position; pull a ring and twist the front arms 90 Degrees to remove them. These brackets also have a convenient, built-in mounting point for the electrical socket.
