Parking-lot block heater receptacles take a beating from ice, snow clearing and drivers yanking cords. The Intermatic WP1250MVXD is an extra-duty die-cast aluminum in-use weatherproof cover for a single-gang box, with a deep 4.625 in lid that hinges vertically and closes over a plugged-in cord. Intermatic lists engine block heaters and walk-in cooler and freezer receptacles among its applications.

Pro tip from the counter
In apartment and workplace parking lots, padlock the hasp (it takes a 1/4 in shank) so plug-in spots can't be used by whoever parks there. A locked die-cast lid also stops the cover being left open and packed with snow.
Best for: block heater receptacles in parking lots, commercial and municipal lots, walk-in cooler and freezer receptacles, industrial exteriors
