Description

30mm Single Block With 90° Fixed Head

The 30mm Single Block With 90° Fixed Head has been specifically developed for the Topper traveller system. Featuring a fixed stainless-steel eye, it allows the traveller line to run directly through the block for exceptionally smooth, low-friction movement from side to side.

A protective sheave skirt surrounds the pulley, helping to reduce the risk of impact damage from the tiller during manoeuvres. While optimised for Topper travellers, this block is equally suited to a wide range of control line applications where smooth, reliable performance is essential.

Key Features

  • 90° Fixed Head with stainless-steel eye for direct line routing
  • Developed specifically for the Topper traveller system
  • Protective sheave skirt helps prevent damage from impact
  • Low-friction, smooth-running performance
  • Suitable for a wide range of traveller and control line applications
  • Patented Dynamic Bearing System featuring twin rows of stainless-steel ball bearings running on a stainless-steel race for superior load capacity, durability, and efficiency
  • Integrated Becket via a large central rivet, providing a lightweight and rope-friendly attachment point for cascade systems
  • Robust, marine-grade construction for long-term reliability in demanding environments
