Low-friction Micro blocks are compact and lightweight. They are ideal for sailboards, smaller dinghies, and lightly loaded control lines on boats of all sizes. Micro block sheaves run exclusively on ball bearing systems for fast trim and release under any load. Delrin® ball bearings are UV stabilized with carbon black for maximum protection. Stainless steel sideplates add strength. Delrin® is a registered trademark of E. I. du Pont de Nemours and Company or its affiliates.
