57 mm Aluminum Flip-Flop Block - Lockoff

The low-profile Flip-Flop blocks are lightweight and can be used for various leads on your boat including halyard leads, mainsheet leads and spinnaker sheet leads. The Flip-Flop block has aluminum hardcoat-anodized side plates and features Hard Lube-anodized aluminum sheaves for strength and corrosion resistance. The high-load flip-flop blocks pivot around the line axis to keep line close to the deck. Hinged construction allows variable leads. Lockoff provides a temporary stop to free up winches.
