Review on 🔌 Leviton 5981-UCL Clear Horizontal While-in-Use Cover for GFCI/Decora Duplex and Single Outlet by Keith Howe

Metal or vinyl siding, sheathing, plywood, etc.) AVOID installing on surface irregularities (joints, gaps, ledges, etc.) , which could affect the tightness. NOT smooth, use silicone sealant to ensure a proper seal. Area under the exhaust cover gasket. I had to wait another day for the cement to set before installing the exhaust cap and silicone gasket. The lid comes with two small plastic inserts that fill in the holes that the power cord goes through after installation which is nice but as my application was a horizontal install I doubt how well the inserts will hold up over time, when removed for use. and not held either - as this is a horizontal application, unless they are firmly attached they can fall out (and disappear under my deck in my case) when the lid is opened. I think we'll see. Otherwise, it appears to be a good, heavy, weatherproof case.
