Sea Sure 00.35CRD 25mm Treble Block with V-Jam Cleat

The Sea Sure 00.35CRD is a 25mm treble block with integrated V-jammer from one of Sea Sure's oldest and best-selling block ranges. Manufactured in the UK from 316 stainless steel, this triple-sheave block combines proven engineering with lightweight construction for reliable performance in marine environments.

Key Features:

• Marine-grade stainless steel side plates and rivets with arnite (plastic) sheave for hard-wearing, lightweight operation
• Creates a 6:1 purchase system to aid in lifting heavier objects and decrease rope load
• Integrated V-jammer cleats the rope at any point during lifting or tensioning
• Accepts up to 8mm rope for control lines, halyards, outhauls, kicking straps, and furling lines
• Hollow rivets for lightness with tough plastic sheaves providing excellent bearing surface
• 25mm sheave diameter with 1250 kg breaking load

This classic design has proven virtually indestructible, with many blocks from this range still found on Olympic class masts. The plain bearing construction and tough Arnite sheave means they just keep on going, providing years of trouble-free service for sailors and marine applications.
