The sheave block is designed for control lines that need to be led safely through a deck, bulkhead, or spar, and it is suitable for both dinghies and smaller keelboats. It provides smooth line lead under high loads. The sheave is made from acid-resistant Grade 2205 stainless steel and runs on a precision bearing that reduces friction under heavy load. The body is made from Grade 316 stainless steel, providing high corrosion resistance and operational reliability. The block is used in systems where lines change direction through fixed structures, e.g. halyard exits, boom outhauls, or pass-throughs in the mast and deck. It works with strong control lines on small and medium-sized rigs. Its robust construction makes it suitable for installations where both high strength and minimal friction are required. Its compact size makes it easy to install in tight spaces.

INSTRUCTIONS FOR USE Install in a suitable pass-through. Use correctly sized line and inspect regularly for wear. Replace the line if there are signs of damage.
