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 Hardkoteanodized side plates and features Hardkoteanodized, Teflon-impregnated 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.
