Harken 57mm Flip-Flop Block w/ Cam Cleat

Harken 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. 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. 

Reversible cam arms adjusts and lock in a wide range of positions for crew accessibility and accommodating of changing lead angles.
