Outdoor cable tray sealing
Waterproof tape is a quick and temporary solution for sealing small gaps or reinforcing connections. Butyl rubber tape is a top choice—it's flexible, sticks to most surfaces even when wet, and resists UV rays. WSP weatherstops are designed to seal penetrations of any type in walls or floors by cable tray, cable conduit, pipe and/or bus duct. The WSP system utilizes a powder coated or galvanized steel frame that encompasses the entire tray or duct at the point of penetration. Working in inaccessible openings is often cumbersome. The effective weatherproofing of cable trays helps to keep weather out, preventing damage to the building envelope, avoiding thermal breaks, maintaining the indoor environment and helping to keep the various cables and wires protected.
