ENERLITES Blank Adapter Insert for Decorator Wall Plates, Unbreakable Polycarbonate Thermoplastic, ETL Listed, 6001-W, White, Standard/Regular

What it is and why I reached for it

I spend a surprising amount of time finishing little details that make a renovation look intentional, and few details stand out like a missing device in a multi-gang plate. The Enerlites blank decorator insert is a small, snap-in filler for a standard Decora/GFCI opening. I used it in two contexts: consolidating a three-gang box down to two active devices during a smart switch upgrade, and covering the spot where a hardwired fan controller used to live. In both cases, I wanted the plate to look like it was designed that way—not patched.

This insert isn’t a device that screws into the box; it’s a cosmetic snap-in that lives inside a decorator-style wall plate opening. If you’re keeping a multi-gang plate and just need one opening cleanly filled, it’s exactly the right tool.

Build quality and materials

The insert is molded from polycarbonate thermoplastic, the same class of “unbreakable” material used in many heavy-duty plates. In hand, it feels rigid with just a touch of flex—enough to resist cracking during installation but not so floppy that it bows when you press on it. Pressing firmly with a thumb didn’t produce noticeable flex once installed, which matters if you’re a fidgeter or have the insert at kid height.

Enerlites rates it heat- and fade-resistant above 100°F and cites a UL94 V-2 flammability rating, plus ETL listing. For a passive insert, that’s what I want to see: it’s not adding any meaningful risk to the box, and it should hold its color reasonably well over time in sun-prone rooms. I’ve had mine in a bright kitchen and a hallway with afternoon sun for months with no yellowing.

Dimensions are standard for a decorator opening—roughly 4.0" tall by 1.4" wide—so it should “read” as a normal Decora device to the eye.

Installation and compatibility

Installation is as easy as it gets:
- Remove the wall plate.
- Pop the insert into the decorator opening from the front (you’ll feel it snap past the internal tabs).
- Reinstall the plate.

On a screwless plate with a subframe, I found it best to snap the insert into the subframe first, then clip on the cover. That kept the lines tight around the insert.

I tried it with a few different plates:
- An Enerlites multi-gang screwless plate: perfect, tight fit.
- A basic Leviton Decora plate: snug with an audible click, no rattle.
- A generic builder-grade plate: slightly looser but still seated cleanly with no gaps.

It’s worth noting that plate tolerances vary by brand. If you want a guaranteed perfect match, pairing Enerlites insert and plate is the safest route. That said, I had no functional issues mixing brands.

One practical reminder: this is a finish piece. If you’re abandoning a device in the box, make sure the conductors are properly capped and tucked per code. The insert doesn’t replace the need to secure the wiring; it just finishes the opening.

Fit and finish

The profile is flat and consistent with a standard Decora device, so it disappears alongside a paddle switch or GFCI outlet. The front face is smooth with a subtle sheen—less glossy than some high-polish plates, more polished than matte. In most lighting, it looks clean rather than shiny.

Color is white. Not warm white, not ivory—true-ish white. In my setups:
- Against an Enerlites plate, the color matched near-perfectly.
- Against a Leviton white plate, I could see a slight shift under bright, cool lighting (the insert read a touch cooler). Most people won’t notice unless they’re looking for it.
- It will not match ivory plates. If your plates are ivory/almond, get the matching color insert or change the plates.

Once installed, the seams were even all around. I didn’t see shadowing or misalignment, and the face sat flush with neighboring devices.

Everyday use

A blank insert doesn’t “do” anything day to day, and that’s kind of the point. In a busy hallway, I watched multiple people reach for the old third switch out of habit, give it a press, and then move on because nothing flexed or wobbled. That’s the test: the insert shouldn’t advertise that you’ve filled a hole.

I also repurposed one by attaching a slim remote cradle using a small piece of hook-and-loop tape. The insert surface is flat and forgiving, so it’s an easy anchor for lightweight accessories. If you ever change your mind, adhesive cleanup is simpler on a removable insert than on painted wall.

Cleaning is a wipe with a damp cloth. The polycarbonate takes fingerprints less readily than high-gloss plates, and it didn’t scuff during a few weeks of active move-in.

Where it makes sense—and where it doesn’t

This insert is the right choice if:
- You’re keeping a multi-gang decorator plate but retiring one device.
- You want a uniform look with adjacent Decora switches/outlets.
- You prefer a snap-in solution over installing a full “blank device” that screws to the box.

Consider a different approach if:
- You’re covering a single-gang box with no active devices. In that case, a dedicated blank wall plate is cleaner and fewer parts.
- You need a more robust physical barrier inside the box (for example, to secure wires mechanically). Use a proper blank device or junction box cover and then a plate.
- Your aesthetic is ivory/almond or a specialty finish. This listing is white; color matching matters.

Value and alternatives

As a single piece, the price per unit is fine for finishing a room or two. If you’re blanking several openings across a renovation, look for multipacks to bring the cost down, or consider buying matching plates and inserts from the same brand for consistency.

Compared with a full blank “device” (a Decora-shaped block that screws into the box), this snap-in insert is faster to install and gives you better alignment with screwless plates. The screw-in blank device is a touch more secure mechanically, but you’ll rarely notice the difference once the faceplate is on.

Small gripes

• Shade of white: It’s close to most mainstream “white” plates but not identical. If you’re sensitive to color differences, match brand to brand.
• Availability of other colors: For projects standardized on ivory or almond, I’d like to see the same part available in those finishes. If you only work in white, this is moot.

Neither of these is a dealbreaker, and the install experience and final look were consistently good.

Safety and code notes

ETL listing and a UL94 V-2 flammability rating are appropriate for a trim accessory. The insert doesn’t substitute for proper box fill, wire capping, or splicing enclosures. If you’re removing a switch, cap the conductors with listed wire connectors and ensure the box remains accessible behind the plate. The insert completes the aesthetic, not the electrical work.

The bottom line

The Enerlites blank decorator insert does exactly what I want from a finish piece: it disappears. It installs in under a minute, feels solid, sits flush in multiple plates I tried, and looks like it belongs next to Decora switches and GFCIs. The materials and safety listings are in line with quality trim, and the surface cleans up easily.

I would recommend this tool. It’s a simple, reliable way to finish a multi-gang plate when one opening no longer needs a device. If you pair it with a matching plate—ideally from the same brand—you’ll get a seamless, professional look. For single-gang abandoned boxes, go with a full blank plate; for anything inside a multi-gang decorator setup, this insert earns its keep.
