PTFE Spiral Binding (often referred to as Spiral Wrap), is a versatile cable harnessing product originally developed for the aerospace industry. Unlike spiral cut tube, spiral binding has the unique feature of contoured edges. This provides extra rigidity for a smaller cross-sectional area (as weight is often an important factor in aerospace or automotive applications). The contoured edges also prevent damage to cables during application and in service. Spiral Binding can also be used for colour coding and abrasion resistance.
