The Ball Lock System
This illustrated booklet describes the features, benefits, and value of working with True-Position Ball Lock Punch & Matrix retainers. A comparison of End & Square Retainers with Backing Plates is covered, along with the inherent problems associated with these products.
Through the years ball lock components have been continually refined to improve precision and reliability. The most significant improvement was the introduction of the backing plug with in-line primary dowel. This change eliminated the need for a packing plate. Backing Plugs along with many other features introduced by Dayton Lamina are discussed in the program.
