TAYMAC MM420C – Frequently Asked Questions

1) Will the TAYMAC MM420 in-use cover fit a standard 1-gang outdoor box?
Yes. The MM420 is built for a standard 1-gang electrical box, and it mounts multi-directionally so you can orient the hood to suit the box position, vertical or horizontal.
2) How deep is the TAYMAC MM420 cover, and will a plug with a bulky cord fit inside with the lid shut?
The hood is 3.05 in. deep, which is what lets a cord-connected plug stay inserted with the cover closed. That depth is the whole point of a while-in-use cover: the device stays energized and protected while a cord is running out of it.
3) Is the TAYMAC MM420 cover listed for wet locations?
The MM420 is cULus Listed and is intended for outdoor and wet-location receptacle installations, which is the application an extra-duty in-use cover is specified for on exterior walls, decks and patios.
4) What does the 16-in-1 configuration on the TAYMAC MM420 actually mean for ordering?
It means one part number covers 16 different device openings, so you don't have to stock a separate cover for duplex, decorator/GFCI, single receptacle and switch layouts. For a contractor or MRO buyer standardizing on one SKU across a building, this cuts the cover count down to a color choice.
5) Will a metal in-use cover be a better choice than the TAYMAC MM420 for a coastal or exterior job?
Polycarbonate works in your favor near salt air. The MM420 is nonmetallic, so there is nothing to corrode, and the polycarbonate resists impact and UV. Metal covers are the pick where physical abuse or a specified metallic finish drives the job; otherwise the nonmetallic version avoids the rust callback.
6) Does the TAYMAC MM420 work over a GFCI receptacle as well as a standard duplex?
Yes. The multi-configurable faceplate adapts to 16 device layouts, which covers decorator-style openings used by GFCI and USB receptacles as well as standard duplex and single-receptacle and toggle configurations.
7) What colors does the TAYMAC MM420 weatherproof cover come in?
Three: clear (MM420C), gray (MM420G) and white (MM420W). Clear is the usual pick when you want to see at a glance whether something is plugged in; gray and white are chosen to blend with the siding or trim.
