Ronstan Series Ball Bearing Block Single Loop Top Blocks

Ronstan Series Ball Bearing single loop top blocks are sailing blocks (pulleys) built to cut friction and handle loads smoothly on sailboats, dinghies, and performance yachts. The loop top head gives you a simple way to attach the block to a padeye, strop, or shackle-free lashing point. These blocks suit control lines, sheets, halyards, and other running rigging.

Key Features:

• Ball bearing sheave: Low-friction rotation lets the line run freely, including under load.
• Single sheave design: Works well for redirecting a line or changing its lead.
• Loop top head: Allows direct attachment with a line or a fixed rigging point.
• Marine-grade construction: Built for use in saltwater and in harsh UV and weather conditions.
• Part of the Ronstan Series range: Available in multiple sizes and load ratings, so you can match the block to your line diameter and application.
