While-In-Use Cover · 1-Gang Extra Duty White Polycarbonate · Horizontal or Vertical Mount · Eaton WIUX-1W
1-gang extra duty while-in-use weather protective cover for outdoor receptacles. White polycarbonate construction with horizontal or vertical mounting, self-closing lid, lockable clasp, and pre-mounted gasket for wet or damp location protection while a cord is plugged in.
What this product is for
This 1-gang while-in-use cover is used to protect an outdoor receptacle while a cord cap remains connected. It is intended for wet or damp location installations where the receptacle needs a cover that stays protective during use.
Use for
Use for exterior receptacles on homes, light commercial buildings, service areas, patios, decks, and similar locations where a weather protective cover is required. Suitable where installers need either horizontal or vertical mounting flexibility on a standard 1-gang device.
Avoid for
Avoid using this cover where a 2-gang layout, low-profile cover, or metal cover is required. Do not assume receptacle compatibility beyond standard 1-gang while-in-use applications without confirming device and box layout.
Best for
Best for electricians replacing a broken outdoor in-use cover or upgrading an existing exterior receptacle to an extra duty cover. The polycarbonate body suits typical residential and light commercial outdoor exposure where corrosion resistance matters.
Installed in
Typically installed on exterior walls, garages, porches, decks, service entrances, and other outdoor receptacle points. Overall size is approximately 5.88 in x 3.93 in x 3.48 in (149 x 100 x 88 mm), so confirm clearance where plugs or transformer-style cord ends may project outward.
Why this product exists
While-in-use covers help maintain protection when equipment remains plugged in outdoors. This extra duty design adds a self-closing lid, lockable clasp, and pre-mounted gasket to help protect the receptacle and cord connection in service.
Compared with similar products
Compared with a standard weatherproof cover, a while-in-use cover protects the receptacle while a cord is connected. Compared with low-profile versions, this style provides more interior space for common cord caps and offers horizontal or vertical mounting flexibility.
