The 19BSMP is a Powerblanket® Summerstep 6' long connectable power cord used to power up Powerblanket® stair heater mats that melt snow. It has 120 volts, a maximum 12 amp, and a 5-15 plug. This power unit's connector can connect to the first or last heated stair mat in each system.
If stair mats are being used for more than one location, a separate power unit must be purchased for each location. Up to 12 amps are allowed per single 6 foot Summerstep power unit. If your connected mats go above 12 amps, you must split up the heated mats and get a second power unit for a separate outlet.
