selden lock block for furlex 300s/td furling systems

This lock block is an original replacement component engineered for use with Furlex 300S and Furlex 300TD headsail furling systems. It forms part of the lineguard bracket assembly, providing a secure locking point that helps keep the lineguard correctly positioned during sail handling.

Proper function of the lineguard and its lock block supports accurate line routing into the drum and along the foil, reducing the risk of line misalignment, excessive wear, or chatter under load. Durable construction suited to marine conditions ensures that this component withstands rigging loads and environmental exposure.

Replacing worn or damaged lock blocks during routine maintenance contributes to smooth and reliable furling performance, improved line handling and extended hardware life on cruising and coastal sailboats.
