Slipping, shoveling and salting when it snows are now a thing of the past. Keep outdoor stairs safe and snow-free with this innovative set of heating stair mats designed to be left outside all winter long. These electric mats work to melt snow on contact at a rate of two inches per hour in order to prevent snow and ice from accumulating. Featuring built-in watertight connectors, they're designed to interconnect with other HeatTrak stair mats and walkways. See how it works!
