Ratchamatic® Flip-Flop Block - 57mm
Small Boat 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 side plates 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.
