Low-friction Microblocks are compact and lightweight, providing fast trim and release under high or low loads. They are ideal for sailboards, smaller dinghies, and lightly loaded control lines on boats of all sizes.
Their free-rolling Delrin® ball bearings, sheave, and sideplates are UV-stabilized with carbon-black additive 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.)
