In most applications, a through deck bush is used to guide rope or wire through a surface, such as the deck of a boat. The deck bush offers protection to the surface it is fitted to, stopping the rope or wire from rubbing and cutting through the surface.
Deck bushes feature radiused corners to minimise wear on the rope/ wire passing through.
Aluminium deck bushes are lightweight and long lasting. Available in a variety of anodised colours. Allen recommend using an isolating agent when fitting aluminium deck bushes to a carbon surface to stop electrolysis.
