This Stelpro portable heater is equipped with a high-performance nickel-chrome alloy element that provides instant heat at startup. This device is perfect for a construction site that doesn't have a nearby heating source. The 20-gauge steel housing protects the heater from impacts, while the handle makes transportation easy and features a special cable storage design. The 6' 12 AWG cable includes a 250 V/30 A three-prong plug with grounding system. Finally, the motor is entirely enclosed and lubricated, not to mention that it features thermal protection with automatic reset. Backed by a 3-year limited warranty.
