Panduit FT300-L Insulating Tube, Fiberglass, 3" Diameter

When equipment is exposed to high temperatures, reliable cable protection becomes mission-critical. The Panduit FT300-L fiberglass insulating tubing delivers heavy-duty thermal and abrasion protection for security, surveillance and networking installations where heat and mechanical wear threaten uptime. This aluminized fiberglass tubing is rated to withstand temperatures up to 1,200°F (649°C), with a nominal 3" (76.2 mm) inside diameter and a generous 50' (15.2 m) reel to minimize joins and speed deployment.

Engineered for practical use, the reflective surface deflects radiant heat while the flexible fiberglass body conforms to irregular shapes, bundles, and conduit entries — making it ideal for routing camera cabling, access control wiring, power runs, and sensor leads. Continuous abrasion resistance protects cables in ambient and confined spaces, reducing maintenance and prolonging cable life. Trusted Panduit construction ensures consistent performance on commercial, industrial, and critical infrastructure projects. Order the FT300-L insulating tubing today to improve cable reliability and simplify installation on your next security, monitoring, or electrical application.
