125mm & 150mm

125mm and 150mm AirBlocks feature Torlon rollers in a self-contained center cage. Rollers stay parallel for low-friction efficiency. UV-resistant, carbon-black Delrin balls carry sideloads.

Used on offshore boats, these blocks offer a no "climb-out" deep groove sheave with radiused edges to protect line. Sculpted aluminum sideplates and thin-profile sheaves make these blocks very lighweight. No stainless-to-aluminum contact prevents corrosion. The 3201 soft attatchment Loop block has a removable dead end post for attatchment to a padeye. Lashings can also be used.
