Description

The Harken 57 mm Cheek Ratchet Block 2137 is designed to provide controlled load handling where smooth trimming and secure holding power are essential. Ideal for control lines that require intermittent holding, this ratchet block reduces load on the sailor while maintaining precise line control.

Mounted in a fixed cheek configuration, the block offers a low-profile, space-efficient solution for cockpits and deck layouts where swivel blocks are not suitable. The 57 mm sheave size suits medium to high-load applications such as mainsheets, spinnaker controls and trimming systems on performance dinghies and keelboats.

Harken’s reliable ratchet mechanism engages automatically under load, delivering added grip when needed while allowing free-running operation when loads are light. Built with durability and efficiency in mind, the Harken 57 mm Cheek Ratchet Block is a proven choice for sailors seeking dependable performance and clean deck integration.
