The Quick-Lock system isn’t just a single product. It’s a one-of-a-kind workout system centered on a common proprietary plate and locking screw, and exercise equipment. The system is comprised of multiple products, which allows for a more enhanced and complete workout experience. Like the patented plate, the locking screw is a unique screw design that quickly inserts and locks (“Quick-Lock”) to hold the weight plates in place. There are three screw lengths that each accommodate a different weight range.
