The 40mm Single block is our go-to dinghy mainsheet block. Also ideal for dinghy jib and spinnaker sheeting systems as well as keelboat control lines.

Built with a lightweight composite cheek, rope friendly Ultra-Strap and Dynamic bearings

Bearings – Dynamic Blocks feature our patented bearing system which uses twin rows of stainless-steel ball bearings running on a stainless-steel rail. This provides a superior load-carrying ability and longevity when compared to other bearing systems which run on a plastic rail.

Ultra-Strap – Our patented Ultra-Strap is used in our 20, 30 & 40mm Dynamic blocks. The Ultra-Strap is unique when compared to other designs because of its coining process. This process strengthens the strap, making it more reliable and hard-wearing as well as making it much more rope friendly than other designs. The Ultra-Strap was the first marine industry block designed to work specifically with a rope attachment.

Becket – The 40mm range features a large central hole, which is designed to be used as becket (tying off point).

    Smells like rubber.
    Flavor Name: Bacon, Size: Medium
    I bought this flavored nylabone for my dog because he had one that he just loved and it finally had to be thrown out. So I bought him this one and he won't even chew on it. All it smells like is rubber. No flavor smell AT ALL. But our other dog chews anything and he chews this so I kept it. I won't buy nylabone again.

    Super chewer approved
    Flavor Name: Peanut Butter, Size: Large
    One of the few safe chewy bones for a super chewer. Very durable, an appropriate price, and a good size for our 70lb pitty.

    The best toys for dogs I could ever find
    Size: X Large
    I have bull terriers. They chew wood for fun... But this brand in the appropiate size and in any shape has been the best thing for them! They last for a very long time (they have not even dented them and they've had one (another shape) for the last two years. Now I bought these bones so that they can play together, each graving one side of it. They have so much fun! They are worth every penny.

    Best chew toy
    Size: Medium (Pack of 1)
    Kong toys are the best. They hold up through the heavy chewing stage. Definitely recommend if you have a heavy chewer.

    Not for aggressive chewers
    Size: Medium (Pack of 1)
    My dog absolutely loved this Kong Goodie Bone at first and was super excited about it. Unfortunately, it didn’t hold up nearly as long as I expected. Within just a few hours she had already torn pieces off of it, and I ended up finding little red rubber pieces all over the house. I wouldn’t recommend this for aggressive chewers at all. It may work better for lighter chewers or dogs that are gentler with toys, but mine destroyed it way too quickly. Disappointing because she really did enjoy it while it lasted.
