Abstract
An article such as a conduit or cable, or a splice closure for a cable, is provided with improved resistance to animal damage by applying a layer of abrasive material to the article. The abrasive material is not only sufficiently hard and thick to act as a physical barrier, but its abrasive nature creates such a harsh, unpleasant grating effect that the animal tends to not attack it at all. The preferred embodiments of the article use either a plurality of granules to form the abrasive material, or a mesh substrate having an abrasive coating thereon. The material should have an effective grit value of no more than 325, and preferably no more than 100. The abrasive material may be applied using an adhesive or, where the conduit/closure is a thermoplastic polymer, various methods are provided for embedding the abrasive material in the polymeric wall.
