Harken 57mm Ratchamatic Flip 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. Sheave X: 57 mm Length: 110 mm Width: 50 mm Height: 67 mm Weight: 156 g Maximum line X: 10 mm Maximum working load: 227 kg
