Control Single Cheekblock

Structured Line Control

The Lewmar Control Single Cheekblock is designed to provide efficient, low-profile line management where clean lead angles and reliable load control are essential. Fixed directly to a flat surface, it offers a stable, space-efficient solution for guiding control lines across decks, cockpits, and interior structures.

Checkblock Configuration

The single cheekblock format allows lines to be redirected smoothly without introducing unnecessary movement or articulation. This fixed geometry ensures consistent alignment and predictable behaviour under load, making it particularly well suited to control systems where clarity of lead and deck organisation are priorities.

Marine-Grade Construction

Manufactured from durable, marine-grade materials, the Control Single Cheekblock is built to withstand the demanding conditions of the marine environment. Robust side plates and a precision-engineered sheave provide strength, resistance to wear, and long-term dimensional stability under repeated use and exposure to saltwater.

Smooth, Dependable Performance

Designed to minimise friction and promote efficient rope flow, the block delivers consistent, controlled operation during trimming and easing. Its solid mounting and stable help reduce vibration and unnecessary movement, supporting accurate sail control and reduced effort during regular operation.

Installation & Application

Well-suited to control lines, traveller leads, and deck-mounted line routing, the Lewmar Control Single Cheekblock integrates easily into both new builds and professional refit projects. Its compact footprint and reliable performance make it a practical, professional-grade solution backed by Lewmar’s trusted deck-hardware expertise.
