Harken Small Boat 57mm & 75mm Flip-Flop Blocks

Harken Small Boat 57mm & 75mm Flip-Flop Blocks
Small Boat Flip-Flop blocks pivot around the line axis to keep line close to the deck. Hinged construction allows for various lead applications.

Lightweight, machined 6061-T6 aluminum cheeks pivot on fiber-reinforced plastic chocks. Free rolling ball bearings, sheave and sideplates are UV stabilized with black additives 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.
