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.
