Nautos Micro Footblock Double is a compact, low-friction, lightweight block system with a smaller sheave diameter of 3/4" (20mm). Designed for all control applications on smaller boats where up to 1/4" (6mm) line is used, this block has a fast trim and releases under both high and low loads. Rollers over a hard axle handle a greater load than ball bearings. 

Easy maintenance: Just flush with mild soap and fresh water. They are ideal for use on sailboards, smaller dinghies, and lightly loaded control lines on boats of all sizes. Use for traveler controls, cunninghams and outhauls, vangs, barber haulers, flag halyards, lead car return tackles and leech cords.
