This cassette is a practical spare part for sailors who want to replace a worn or damaged sheave in an existing Series 40 system. It gives the block new life and ensures continued reliable line handling on board. The cassette is designed as a complete unit with a 40 mm ratchet sheave, so it works smoothly and with proper grip on the rope. The material selection ensures low friction and efficient load handling in both trim and control systems. It fits Series 40 installations and is used as a direct replacement in models where cassette-based replacement is possible. This solution makes maintenance simple and reduces the need to replace the entire block. The cassette is light and compact, making it relevant on board dinghies, sportsboats, and smaller keelboats. It is particularly suitable in systems where the ratchet function is important for keeping the line under control.

INSTRUCTIONS FOR USE Remove the old cassette according to Ronstan’s instructions and install the new one in the same position. Check that the sheave rotates freely before putting the block into use.
