Harken block
Bought when I changed the wheels - arrived well wrapped with the wheels and on time. Easy to fit quality product. Good service
Easy to fit and seem to be robust as a replacement for my Trolley wheels. Arrived as promised very well wrapped. Worth checking if you need new washers and clips to add to your order.
Though not cheap this control line swivel block is just the job. Well worth the money imho.

Slides easily through the blocks whilst providing firm grip

Quality material and design enables my lug sail to be stowed securely on it's spars
Great wide and grippy tyres for a shingle/sharp launching area and compound for an RS400.
Receive fantastic service couldn’t help any more if they tried. Arranged for me to collect my order at a time that suited even when it was outside of working hours. Much appreciated, thank you sailing Chandlery.
Excellent gloves, perhaps the best I have used. The fingers are long enough to provide protection from sheets/halyards and fit nicely so that ropes cannot get between the glove and finger. If the winter gloves are any guide they should also be very durable.
