Allan Dog Bone

Dog Bones can be used in a variety of applications. Ideal for use with soft shackles as rope stops or spliced to the end of a halyard to make a quick and easy attachment for the sail.

CNC Machined from aluminium, the Allan dog bones are extremely hard-wearing.

Why use a dog bone?

Dog bones are extremely lightweight. Replacing a metal shackle for a dog bone on the end of a jib sheet will help reduce damage when the clew slaps against the mast, deck or sailor! Reducing the weight on the spinnaker or jib clew will also help the sail set more efficiently.

Streamlining any fitting is always a bonus, it will help reduce windage, thus making the boat more efficient. It can also stop snagging.

There’s nothing worse than needing to undo a shackle or knot in a hurry, especially as both can require tools in many situations if over tightened. A dog bone however is usually attached via a simple loop in the rope which is quickly and easily undone by hand.

Allen dog bones are shaped differently to others on the market. Our triple cut-out design allows the rope to be looped perfectly around the dog bone without loosing any strength in the rope. The two protruding edges between each of the three tapered cut-outs act as a barrier which stops the dog bone from being able to slip off of the rope.

Cross holes on each end allow for an attachment of a leash line. The end is also recessed to allow the small knot of the leash line to sit inside the dog bone to keep it flush.

Examples of use:
Main halyard, Jib sheet, Spinnaker sheet, Tack lines, Tie-on blocks, High load thimbles, Cunningham system, Clew tie.
