Wiremold WMFB1DRB – Frequently Asked Questions

1) What size opening do I need to cut for the Wiremold WMFB floor box?
The WMFB single-gang floor box measures 5.0 in deep, 3.13 in wide, and 4.0 in high, so plan your floor penetration and the cavity below around those numbers. The 4.0 in height is the figure to check first on a wood floor with limited joist depth or a shallow slab pour.
2) Will a standard single-gang receptacle and cover fit the Wiremold WMFB floor box?
Yes. The WMFB is a single-gang box, so it takes common single-gang devices and covers. The assembly is supplied as a complete floor box with the components needed for floor-level electrical access, and the version with the brass cover comes with a tamper-resistant duplex receptacle already configured for two plugs.
3) Does the Wiremold WMFB floor box come with a receptacle, or do I buy that separately?
The brass-cover WMFB1DRB ships as a complete assembly with a tamper-resistant receptacle giving two plug positions, plus the cover. You are not sourcing the device or the plate separately for that configuration.
4) Is the Wiremold WMFB floor box metal or plastic?
PVC. That keeps the box light, 1.05 lb, and gives it resistance to moisture at floor level. If your job spec calls out a cast iron or stamped steel floor box for concrete pour, this PVC assembly is not that product.
5) Can I use the Wiremold WMFB floor box in a retrofit over an existing floor?
It is built for renovation and retrofit work as well as new installs, and at 1.05 lb with a 5.0 x 3.13 x 4.0 in body it drops into tight cavities. The controlling number on a retrofit is the 4.0 in height, so confirm you have that much clear depth below the finished floor before you cut.
6) What is the exact part number for the Wiremold single-gang floor box with the brass cover?
WMFB1DRB is the Wiremold catalog number for the single-gang floor box assembly with the brass cover and the tamper-resistant two-plug receptacle. Use that number when matching a submittal or reordering to keep the floor plates consistent across a building.
7) Why does the WMFB floor box use a tamper-resistant receptacle, and where does that matter?
Tamper-resistant outlets have internal shutters that block foreign objects from a single blade slot, which is why they get specified in schools, healthcare, and public areas. Since a floor outlet sits where feet, mop water, and curious hands reach it, that shutter is worth having. The WMFB is used in office buildings, retail, educational and healthcare facilities, conference rooms, and open plan work areas.
8) What finish is the cover on the Wiremold WMFB floor box?
Brass. That is the finish to pick when you are matching existing brass floor outlets in a lobby, conference room, or older office fit-out. If the rest of the floor plates on the job are nickel or aluminum, this one will read differently.
