Mulberry 99111 – Frequently Asked Questions

1) What should I use if the device in the box is a standard duplex receptacle and not a twist-lock?
Use a duplex-cut plate rather than the Mulberry 99111, whose opening is sized for a single 20-Amp TL twist-lock receptacle. The Bryant P8 Series 1-Gang Duplex Wallplate is cut for a standard duplex receptacle, and the Cooper Wiring Devices 2138WBOX from the 21 Series is a thermoset combination wallplate in white. Confirm the device face before ordering, since a twist-lock opening will not frame a duplex.
2) Can a Leviton 80704 1-gang wallplate be used in place of the Mulberry 99111?
No, not for a twist-lock opening. The Mulberry 99111 has a pre-cut opening dimensioned for a single 20-Amp TL (twist-lock) receptacle, so the hole matches the round locking device face. The Leviton 80704 is a thermoplastic nylon device-mount commercial grade 1-gang wallplate in gray, so it is a different opening and a different material. Both are single-gang and fit standard single-gang boxes, but the 99111 is the one cut for a twist-lock receptacle.
3) The twist-lock receptacle was removed and the box is being abandoned - what plate covers it?
A blank plate is the right part there, not the Mulberry 99111, which has an open 20-Amp TL cutout. The Pass and Seymour WPB Series blank wallplate comes in brushed aluminum for a metal finish, and the Leviton PJ23-E is a thermoplastic nylon blank in 2-gang midway box mount. Match gang count to the box: the 99111 is a 1-gang plate.
4) What size box does the Mulberry 99111 twist-lock plate mount to?
It is a 1-gang plate sized for standard single-gang wall and device boxes, so it drops onto the same openings you already have throughout a building. Nothing special is needed on the box side; the only fit question is that the device behind it is a 20-amp twist-lock receptacle.
5) Is the Mulberry 99111 wallplate metal or plastic?
Steel. That is the main difference between the 99111 and the nylon or thermoset plates common in this category, and it is why it holds its shape in shops, mechanical rooms, and other spots where a plate takes knocks. If you want a non-metallic plate in the same single-gang footprint, the Leviton 80704 thermoplastic nylon commercial grade 1-gang plate is the alternative.
6) What part number do I order for the Mulberry ivory steel twist-lock plate?
Order Mulberry 99111. It ships as a single 1-gang steel plate with one 20-amp TL opening in ivory, and there are no finish or size options to specify on it.
7) I am replacing a damaged cover on a twist-lock outlet in a shop. Do I need to pull the receptacle out?
No. The 99111 is a cover plate only, so you kill the circuit, remove the old plate screws, and set the steel plate over the existing 20-amp twist-lock device. The receptacle, box, and wiring stay as they are. The plate covers and protects the device from dust and incidental contact; it does not include the receptacle itself.
8) Is there a non-metallic alternative to the steel Mulberry 99111 wallplate?
For plastic plates, the Cantex 5133330 is a PVC single toggle switch wallplate and the Leviton PJ23-E is a thermoplastic nylon 2-gang blank in commercial grade midway size. Both are non-metallic, but neither carries a 20-Amp twist-lock opening the way the Mulberry 99111 steel plate does, and the Cantex is cut for a toggle switch while the Leviton is blank. Choose by the device in the box first, then by material.
9) What is the equivalent if the twist-lock device sits in a two-gang box?
The Mulberry 99111 is a 1-gang plate sized for standard single-gang wall boxes, so a wider box needs a 2-gang plate. In 2-gang, the Pass and Seymour TP703LA is a TradeMaster nylon plate in light almond, the Leviton PJ2-E is thermoplastic nylon midway in commercial grade, and the Eaton 7729V-SP is a decorator plate in triple-gang if the box is wider still. Those are not cut for a 20-Amp twist-lock face, so verify the device opening before you order.
10) Will a Bryant NP26W or Bryant PJ plate fit the same twist-lock receptacle as the Mulberry 99111?
Treat them as different parts. The Bryant NP26W is an HWS Series P26W 1-gang wallplate and the Bryant PJ Series is an M-size plate for wiring devices, so the PJ is a midway-size body rather than a standard 1-gang face. The Mulberry 99111 is steel in ivory with a pre-cut 20-Amp TL twist-lock opening, so match the plate opening to the exact receptacle configuration rather than assuming any 1-gang plate drops on.
11) Will Ivory match the plates already installed in my building?
Ivory is one of the two most widely used neutral device colors in both commercial and residential trim packages, so the 99111 generally blends with existing ivory switch and outlet plates. If your building standard is the warmer light almond rather than ivory, they will read slightly different side by side; a Pass & Seymour TradeMaster plate in Light Almond is the match in that case.
12) Can I use the Mulberry 99111 as a blank cover over an unused single-gang box?
Not really. The 99111 has a pre-cut twist-lock opening, so used over an empty box it would leave a hole. For a true blank on a single-gang box, go to a blank plate such as the Pass and Seymour WPB Series blank wallplate.
13) I need a matching plate for a phone or data jack in the same room - what pairs with the Mulberry 99111?
The Mulberry 99111 covers a 20-Amp twist-lock receptacle only, so communications outlets take a separate plate. The Eaton 35324W is a wallplate with a 4-conductor data/voice modular jack, Type 625B4, and the Eaton 3533-4W is a surface mount telephone jack wallplate in white thermoplastic for RJ11/RJ14. Note the 99111 is finished in ivory while those Eaton plates are white, so the trim colors will not match exactly.
14) Is there a bulk option if I am standardizing plates across a building rather than replacing one twist-lock cover?
The Mulberry 99111 is ordered as a single steel 1-gang plate with a 20-Amp TL opening, which suits a one-for-one device replacement. For volume standardizing on a decorator-style opening, the Leviton 16252 Decora single-gang device wallplate ships as a pack of 100. That is a Decora opening, not a twist-lock cutout, so it will not serve the twist-lock positions.
