Harken's 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 blocks have Delrin ball bearings that are UV-stabilized with carbon black for maximum protection. They also have stainless steel sideplates to add strength.
Micro blocks are commonly used for lightly loaded control lines including cunninghams, outhauls, vangs, traveler controls, barber haulers, flag halyards, leech cords and lead car return tackles on dinghies and keelboats ranging from the Naples Sabot, to the Moth, to the Etchells.
This cheek block requires #10 (5mm) RH Fasteners and #8 (4 mm) RH fasteners.
