Harken wire blocks are designed for strength and to carry wire halyards and high-strength control lines on all types of boat.
These Harken blocks have high-load composite bearings with a lube anodised sheave for strength and corrosion resistance.
The wire blocks are available in three different sizes from Harken, the 25mm, 38mm and 51mm. The most common in smaller boats are the 25mm and 38mm.
You'll see the 25mm forkhead wire block at the top of the Laser kicker set up and the larger sizes used on internal mainsheet systems to support thin dyneema running through the blocks in a purchase system.
As an example we use the 38mm versions on our Tornado internal mainsheet system where 3mm dyneema runs through the purchase systems. Running thinner dyneema provides the strength you need but with far less friction making the system run smoothly.
If you have any questions about Harken Wire Blocks then get in touch, we are always happy to discuss your sailing systems and what might work best for you.

Helpful and fast service
Helpful and fast
Really speedy dispatch after easy buying process.
Great to see minimal packaging used to help the environment.
Great price. We'll informed with delivery updates. Once arrived it was better than I expected. Great cover well made
The breathable poly cotton cover is very good quality heavy material. Fits the boat well.
Delivery very prompt.
The twine was exactly as described and perfect for the job.
Responded immediately and with excellent knowledge and customer service. Fast delivery. Can’t recommend enough!
the product is perfect main sail repaired ready to go
Excellent strong lightweight clips ideal for swapping out flags easily
to be used for trapeze lines - hopefully will withstand UV better than other cheaper versions.....
Ordered and it arrived within 2 days.. Superb personalised service. Would highly recommend this website. Thank you.
Super service, dispatched next day and arrived in time... Fantastic service.
These blocks are a nice balance between quality and weight - I needed something light for jib sheet clew blocks as I didn’t want too much weight hanging on the corner, and it needed to run smoothly (and stay running smoothly) - these fit bill nicely. The sheave is also more protected than other blocks where the edges can get chewed up where they hit the mast.
Used the Dyneema to make soft shackles. Spliced easily but was noticeably “tighter” when pulling through the tails than I found for similar 4mm Dyneema. Glad for the set of Fids. However I ordered the black colour and whilst it was easy to mark up white Dyneema for planning the splices I couldn’t see the pen marks I made on the black rope. I suppose I should have thought of this and got a white marker! Overall very happy.
Easy to order and promptly sent. Used the 4mm Dyneema to make soft shackles - my first attempts - found it easy to splice and it has made some useful and strong shackles.
