SRA protective tube seals are used at intersections and on unassigned (i.e. empty) protective cable tubes to protect them against sand. Through the pre-stamped sealing bodies, tubes containing cables are protected against the ingress of fine sand. These high-quality shaped parts fit inside cable duct tube sleeves and plug-in tips. They are quick and easy to install and eliminate the need for unsafe makeshift solutions. No tools are required for removal and subsequent reuse.
