The RDSS-CLIP-100 is a mastic sealant-clip designed to be used in combination with the Raychem RDSS-100 inflatable duct seal. It is made from a high-temperature mastic mounted on an installation stick, allowing for easy insertion between cables to seal configurations of three or more. One clip can seal up to four cables, and for each clip used, the maximum cable bundle diameter must be reduced by 5 mm. This system provides a simple and effective method for creating a watertight seal in multi-cable applications within power cable ducts.
