Ronstan Series 60 Core Block™, Single with Becket and Cleat

18 in stock

Ronstan Core Blocks™ are high-strength blocks built for high static loads. Self-lubricating composite bearings give durability and minimal maintenance under extreme tension – ideal for halyards, vangs and backstays, where structural reliability is critical. An integrated cam cleat locks the line instantly and releases it with a flick of the wrist – no separate cleat needed. The integral becket gives the line a secure dead-end, so the tackle can be rove to an odd-numbered purchase.

At Saildeck Gear we specialise in technical rigging, blocks, winches and deck hardware for yachts from 30 to 60 feet – and we know that every boat is different. Working loads, mast dimensions, deck layout and how you sail (cruising, racing or charter) all change what you really need.

That’s why we don’t publish a fixed price on the product page: we’d rather talk to you first.

Tell us which product you’re interested in and which boat it’s going on, and we’ll prepare a quote tailored to your set-up, with technical advice included and no obligation.

If you have any questions about compatibility, dimensions or which part is right for your rig, you can also get in touch here. We normally reply within 24–48 hours.

The information you provide will be used solely to deal with your enquiry. Please see our privacy policy for more information.
