Moeller Precision Tool’s exclusive and innovative, true one piece construction retainer was developed using intensive market research and user input. True-Set® retainers are the only products manufactured from a through-hardened single piece of high quality alloy tool steel. The design eliminates stacking tolerance errors, allowing better punch positioning. The integrated design provides an end to the aggravation of lost plugs, or the separation of welded backing plates. True-Set® retainers disperse the stamping force over the entire retainer surface, protecting die shoes.
