The moulds used in this high precision industrial process are sculpted from blocks of metal weighing several hundred kilos. Quick Release Strap The metal buckle attaches to a high quality safety strap. On the other strap is a ribbed plastic tab. Insert the ribbed plastic tab into the metal buckle. You ll hear a light "clicking" sound. Continue to slide it until you get a comfortable, snug fit. Pull the ribbon on the lever to release. For additional initial adjustment, use the metal slider buckle on the strap with the ribbed plastic tab to take up excess strap.
