This cheek block provides efficient line handling on smaller boats, where light trim lines require low friction and precise control. It is relevant for trimming tasks where fixed mounting and a compact format are an advantage. The block ensures stable operation during active sailing. The construction uses a 2-stage ball bearing system, which provides smooth rotation under load. The sheave is made of acetal with high compressive strength, and the sides are made of reinforced nylon for durable operation. Fastening is done with a 5 mm and a 3 mm bolt, providing solid mounting. The block is used as a fixed lead point on the mast, boom or deck. It is suitable for small lines in systems such as cunningham, leech trim and other control functions. It fits into different rig setups where low weight and stability are important. The compact shape makes it useful where space is limited. It provides smooth line handling during repeated adjustments and is relevant for both cruising and training sailing. The lightweight construction contributes to quick response in the trim.

INSTRUCTIONS FOR USE Mount the block with the specified bolt sizes. Ensure a flat surface and proper tightening. Lead the line through the sheave and check for free movement before loading.
