TayMac MG420CS Nonmetallic Extra Duty In-Use Cover - Weatherproof

In this review of the TayMac MG420CS nonmetallic extra duty in-use cover, the bottom line is straightforward: it is aimed at homeowners and contractors who need a weatherproof, tamper resistant GFCI solution that installs quickly and includes everything needed. The kit combines a clear/gray heavy-duty polycarbonate cover with a 15 amp weather resistant tamper resistant GFCI receptacle and mounting hardware, so the biggest reason to buy is the convenience of a complete, quick-fit package that protects an outlet while in use.

Key Features

• Patented quick-fit keyhole mounting system: lets a single installer snap the cover into place in under a minute for fast, fuss-free installation on a compatible box.
• Weather resistant tamper resistant GFCI: provides ground-fault protection with tamper resistance built into the receptacle for safer outdoor use.
• Complete kit: includes the box, 15A WR/TR receptacle and cover so there is no need to source additional parts before installation.
• Attached gasket and mounting hardware: the included gasket and screws simplify sealing the cover to keep moisture out when the outlet is in use.
• High-impact polycarbonate construction: an extra duty, nonmetallic housing offers durability and impact resistance while staying lightweight and corrosion resistant.

Who It's For

This kit is a good fit for homeowners who need an outdoor or garage outlet that will be used with appliances, lights or power tools and must remain protected from rain and snow. It is also useful for electricians and contractors who prefer a single SKU that includes a weather resistant GFCI and all mounting components for quick jobs.

Those who should look elsewhere include buyers seeking a metal cover for industrial environments or anyone who wants a different amperage or a non-GFCI receptacle - this package is explicitly a 15A WR/TR GFCI kit in a nonmetallic housing.

Pros & Cons

Pros

• Everything needed is included, making installation straightforward and faster than assembling separate parts.
• The quick-fit keyhole system noticeably reduces installation time for a single installer.
• Extra duty polycarbonate housing is weather resistant and holds up well to outdoor exposure in typical residential use.
• Attached gasket and mounting hardware improve the weather seal right out of the box.

Cons

• Some customers reported mixed functionality with the GFCI receptacle itself, so occasional unit failure is a realistic limitation to consider.
• Nonmetallic construction may not suit heavy industrial sites where a metal cover is preferred.
