Selden Block R60+ Single, AL Sheave

The R60 60 mm Manual Ratchet Block – Single Swivel (Aluminium Sheave) is a high-performance rigging block designed to offer controlled line handling and reliable ratchet action aboard sailboats. Featuring a robust aluminium sheave and precision ratchet mechanism, this block provides positive engagement — holding line position under load while allowing controlled rotation when trimming or easing.

The 60 mm sheave is equipped with a ratchet mechanism that produces audible and tactile feedback as the line moves, giving sailors confidence in sheet control during manoeuvres, reefing or sail adjustments. The single swivel head allows flexible alignment with changing load directions, and the durable construction stands up to demanding marine conditions.

This block is ideal for applications where secure movement and adjustment of sheets or control lines is required — especially on cruising yachts, performance boats and anywhere ease of handling is paramount.
