2:1 halyard block for Seldén CX45, CXr45 and CXe45 Code Zero furler.

Machined and hard anodized aluminium block with captive pin. Acetal sheave.

To boost the performance when using a Code Zero, the halyard load must be higher than what normal halyard boxes and stoppers can handle. Therefore, a 2:1 purchase needs to be arranged by fixing the dead end of the halyard in the mast and letting it run

This block is also ideal for a 2:1 purchase on the main halyard.

Great quality, great price, and pup approved!
Size: Pack of 100
This is such a good deal for the price!! Our order arrived faster than expected and was packaged securely. These ears are big too, much bigger and more natural looking than the ones I've been buying at the local store. Most importantly, the pups approve! Will definitely order again!

Nice Pig Ears
Size: Pack of 40
Nice sized pig ear, but not as big as some suggested. They are the perfect size, no smell, no grease, pups love them and no unwanted side effects that have happened with other brands. Happy Pups. Will order again. They are a great price for a quality dog treat. Glad I found these.
