The 29mm block from Harken, also known as the Carbo block is a lightweight, strong, reliable and affordable pulley block.
Harken 29mm blocks are popular on many sailing dinghies. 29mm carbo blocks are made with lightweight nylon resin side plates which replace the stainless steel straps found in other Harken blocks. Densely packed glass fibers reinforce the resin for strength.
The Harken 29mm block comes in various designs with these compact blocks having very high working loads for safe, easy trimming. You can expect breaking loads of up to 907kgs on some of these blocks.

Amazing service, the staff got our order in with no issue and quick delivery. The replica mast are a perfect alternative.
Excellent service. Arrived very quickly. Highly recommend, have used Sailing Chandlery several times - always quick and efficient.
I have the 270 boots 2020, But these 170 boots are great, much easier to get on and off and very grippy and comfortable
Great range of products, very efficient service, item arrived well packed and on time
Really strong, does what it needs to!
Great product, does the job for a good price
Perfect product at good price and fast delivery. Thank you.
Best spring/summer hiking wetsuit.
As per usual the Sailing Chandlery team got these to me in a flash! Amazing service!!!
I have previously used the Superwarm version of this hiker and it was brilliant!
I purchased these as I get far too hot in my winter hikers during the sweaty summer months!
Only used once so far, but were warm enough in 15 degrees C and worked exactly as expected!
Good size handle, comfortable grip. I find I have to go down a size in needle than that advised for the rope I’m splicing.
Fantastic service and reasonable prices
Excellent service product delivered very quickly and exactly the item I required.
These were fine. But what was an issue was the number of emails I received after.
This is my most used item in my sailing bag. Keeps me warm on colder days underneath layers and I also wear it on top in the summer. The fleece lining inside is very comfortable.
These are brilliant socks. I tuck them inside my Superwarm wetsuit and because the seems are sealed it stops any water getting to my feet.
Small and springy - exactly what I needed !
But usual great service from Sailing Chandlery !!
