Ronstan Core Block - Single Stand-Up Swivel Block
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.
- Strong precision cast padeye base.
- Resilient rubber stand-up boot prevents clatter & block falling down when not loaded.
- Central hub hole can be used as a becket take-off or tie-up point.
- Alloy Rope/Wire sheave version also available.
