Manufacturer part #: HSB411
Nylon resin sideplates are densely packed with long-glass fibers for a compact block with a high strength-to-weight ratio. Machined aluminum sheaves are Hardkote anodized for strength and corrosion resistance. Eight facets hold line securely. Ball bearings, sheave, and sideplates are UV-stabilized with carbon black for maximum protection.
The 40 mm ratchets are ideal for jib sheets and spinnakers where size and weight are critical. The HSB411 has on/off switch in one of the sheaves and a regular rolling sheave ; other 40 mm ratchets are always in ratchet mode.
