Harken 2144 57mm Carbo Ratchamatic Flip Flop Block

Small Boat Flip-Flop blocks pivot around the line axis to keep the line close to the deck. Hinged construction allows for various lead angles.

Lightweight, machined 6061-T6 aluminum cheeks pivot on fiber-reinforced plastic chocks. 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.

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 accommodation of changing lead angles.
