Each standard Heat Tape Pro cable has a 4-foot unheated lead.
However we have a new Product that has an Extra-Long 50 foot lead length. It’s call Heat Tape Pro XL.

This lead-length is in addition to the the listed heat tape length, so a 50-foot Heat Tape PRO will actually be 54 feet long with 50 feet of it heated and the remaining 4 is an un-heated cord with plug. A 50-foot Heat Tape PRO XL will actually be 100feet long with 50 feet of it heated and the remaining 50 is an un-heated cord with plug.
