Ronstan Core Blocks

Incredibly smooth running, long lasting block thanks to the aluminium cheek plates and the Ronstan Universal Bearing 2-stage bearing system. An acetal sheave and stainless fixings complete the durable package.

For reliability and a long service life, these blocks are recommended for mainsheet, halyard, vang and spinnaker sheet applications on boats up to 16m (60ft) and general / control line applications on larger yachts. The 45 mm block is great for furling lines, and other control lines where strength and durability are required.

Features:

  • Class leading performance and sleek, contemporary styling.
  • Excellent dynamic and high static load performance.
  • Less than half the friction of the nearest competitor.
  • Universal head can be fixed at 0° or 90° or left free to swivel.
  • Head posts can be locked at 0 or 90 degrees, by using a 2.5mm Hex/Allen Key.
  • Central hub hole can be used as a becket take-off or tie-up point.
  • Alloy Rope/Wire sheave version also available.
