TC-ER Rated Cables

Do it without conduit!

Tray App

With LAPP TC-ER rated cables, you can install cable faster and even reduce or eliminate the need for conduit which translate in cost reduction without compromising the installation quality.

UL type TC Tray cables are permitted in cable trays by the NEC. Tray cables with the –ER suffix can extend much further in certain applications if given adequate protection and support.
