The Intermatic WP1250MXD is an extra-duty die-cast aluminum in-use weatherproof cover for double-gang boxes, built for exposed commercial and industrial receptacles. Its 4.625 in deep lid hinges vertically, closes over two plugged-in cords up to #12 AWG, and stands up to impact and hinge abuse that would crack a plastic cover.

Pro tip from the counter
Where two vehicles share a post, such as fleet yards or double parking stalls, this cover lets both block heater cords (up to #12 AWG each) stay plugged in under one closed lid, instead of mounting two single-gang covers side by side.
Best for: fleet yards and shared block heater posts, loading docks, walk-in cooler and freezer receptacles, municipal and industrial sites
