The HeatTrak Stair Mats are designed for industrial use. Built with non-slip, UV-protected rubber, they can endure harsh weather and be left outside for the entire winter season. The mats plug into standard 120V or 240V outlet, generating heat to melt snow at a rate of 2" per hour. Mats can either come as a single mat or linked together in a set of multiple stair mats, connecting up to 10 on a single outlet.
