Ronstan Core BlocksRonstan Core Blocks™ offer a true all round solution. Thanks to the 2-stage bearing system, stainless steel fixings, aluminium side plates and acetal sheaves, Core Blocks are ideal for both high dynamic and static loads. Cost effective, reliable and with a long service life, these blocks are the right choice for sheets, halyards and control line applications for both cruising and racing.

Features:

  • The Ronstan Universal Bearing 2-stage bearing system - Combines high compression strength carbon black acetal ball bearings for minimum friction under moderate loads with a sliding acetal bearing on a polished stainless steel race for low friction under heavy loads.
  • Aluminium Cheek Plates - Block side plates are manufactured from highest quality alloy for maximum strength. The flared cut-away design minimises weight, allows easy rinsing with fresh water and minimises rope wear.
  • U.V. stabilised Acetal Sheaves (Alloy sheaves available for use with wire)
