ABSTRACT:
A rugged and durable cover (22) for a wire rope sling (10) that encloses the length of the sling (10) and prevents particulates from being scraped from a soft nylon coating (20) of the sling (10) and enter the clean room environment of a spacecraft assembly high bay. The cover (22) is readily removable to allow the sling (10) to be visually inspected, such as is necessary during a proof load test. The cover (22) is secured to the sling (10) by a zipper type connection (48) running the length of the cover (22), and is connected to the sling (10) at both ends by straps (24), such as tie wraps. In a particular embodiment, the cover (22) is Zippertubing made of a VNH material and including a Z-track connection.
