Raychem Gardian pre-assembled self-regulating heat trace cables are designed for pipe freeze protection of residential water pipes and small roof and gutter de-icing applications. They are available for 120 V and 240 V applications. Raychem Gardian 120 V cables are ideal for smaller jobs such as roof and gutter de-icing on porches and overhangs, as well as for pipe freeze protection on pipes up to 2-1/2 inches in diameter. Raychem Gardian 120 V cables are available in 6, 12, 18, 24, 50, 75 and 100 foot lengths, and each comes assembled with a 30-inch power cord and plug. Due to their short lengths, Raychem Gardian 240 V cables are designed only for pipe freeze protection applications on pipes up to 2-1/2 inches in diameter. Raychem Gardian 240 V heating cables are available in 6, 12, 18, and 24 foot lengths and each come assembled with a 30-inch power cord for terminating in a junction box.
