3M™ Re-Enterable PST Dome Closure Kit offers a reasonable method of safeguarding butt splices for pedestal and pole-mount applications. The splice is enclosed in a split polypropylene dome, which is clamped together with a steel latch and sealed with an O-ring. The dome closure ensures fast, rugged splice protection with easy re-entry.
3M™ Re-Enterable PST Dome Closure Kit protects the splices from the harmful effects of moisture, insects and UV light. The flexible tubing material adjusts to the shape of the collar, sealing out both water and air. The expanded ethylene propylene rubber tube on the base of the enclosure protects from environmental elements. Pulling a plastic rip cord on the PST allows it to shrink to the minimum outside diameter required to form a tight seal.
