Allen 20mm Pulley Blocks

We've been big fans of Allen sailing kit for a number of years and have now expanded the range of Allen blocks on offer, in this article we look at the range of Allen 20mm blocks. Small, compact, lightweight and enough selection for most jobs on your sailing dinghy.

Allen 20mm Blocks Available

The 20mm blocks we have available are a selection of the most popular:

  • Allen 20mm Dynamic Block
  • Allen 20mm Single Block with Swivel Head
  • Allen 20mm Single Stand Up Block
  • Allen 20mm Single Fork Head Block with Hook
  • Allen 20mm Dynamic High Load Block
  • Allen 20mm Double Block
  • Allen 20mm Double Block with Becket
  • Allen 20mm Triple Blocks
  • Allen 20mm Single Tii on Block
  • Allen 20mm Double Tii on Block

20mm Dynamic Blocks

Allen 20mm dynamic blocks are made from a mixture of polymers with high strength 316 stainless steel. The ball bearings inside are also made from stainless steel.

20mm Tii Blocks

Lightweight blocks which you can attached to your boat using the soft shackle that comes with the block. These blocks are reinforced with stainless steel in the right areas.

20mm High Load Block

Upgraded from the standard dynamic block with a stainless steel sheave for the rope to run around. This adds extra strength and doubles the working load of the pulley to an amazing 250kgs.

Tiller joint

Fitted perfectly very quick to arrive

Gill Aqua Parka Blue Jay Dark Navy

Was looking for one of these type of coats not for sailing but for dog walking and came across the Gill site. Coat exactly what I wanted, loving the inside pocket, warm, weatherproof and comfortable. Also looks stylish in the two-tone blues and well priced too. Thumbs up all round

Great service

The handle was out of stock so i used the 'notify me when available' button. I was duly notified, I ordered and it was delivered swiftly.

Does the job

I brought this for some running rigging on the boat, it arrived quickly and appears to be really good quality rope. It was a good price, I shopped around a bit and it was delivered very quickly. I would definitely buy from sailingchandlery.com again.

Catz balloon tube

Quick delivery, the inner tube looks good quality, time will tell its durability
Helpful staff which was a blessing as their tube is only shown as fitting the 16” tyre, whereas my ballon wheel was 20”,…..but fits both !
It fits OK and under pressure it seems to expand to fit the Catz bigger tyre

I think Sailing Chandlery could probably pick up a few more tube sales if they advertised it as fitting BOTH size tyres…l almost bought my tube from Germany !

Good General Rope

This rope is great to use to tie small fenders, which I use on my sports boat when needed.
Sailing Chandlery have a great range of ropes and a really quick online service so all good from me.

4mm 8 Plait Standard Polyester Rope
A thoroughly good level of service

I recentiy made a purchase from this company and I was incredibly satisfied with the high level of customer service from the ease of purchase, follow up communication and devilry. 10/10

RWO Bung and Socket x2 - Black
Simple, good quality hatch

I bought two of these to cover holes in the deck where previously had had compasses on my 505.
No problems to fit and after sailing in strong winds where the deck is covered in spray, no leaks at all.
Wouldn't hesitate to order again.

This is a good thing

Really handy to have this one instead of the standard fiddly ring.

Did not stick to the lower part of ILCA mast

Wanted to use it on the lower part of ILCA mast. Unfortunately it did want to stay and come off after the first sail.
