Harken 57 mm and 75
mm Flip-Flop Blocks pivot around the line axis to keep line
close to the deck. Hinged construction allows for various lead angles.
Lightweight, machined 6061-T6 aluminum cheeks pivot on fiber-reinforced
plastic chocks. The sheave runs exclusively on a ball bearing system for
fast trim and release under any load. Ball bearings, sheave, and sideplates
are UV-stabilized with carbon black for maximum protection.
The Ratchamatic versions roll freely in both directions under low loads
and automatically engage a ratchet mechanism as loads increase, giving
sailors a holding power of up to 15:1. The ratchet engagement can be adjusted
to a higher or lower load depending on the sailor's strength, sailing style
and system usage.
Reversible cam arms adjust and lock in a wide range of positions for crew
accessibility and to accommodation of changing lead angles. |
