3/8-inch deep wall plates with beveled edges are specialty switch and outlet covers designed for installations where an electrical box or device extends beyond the finished wall surface. Their deeper profile helps conceal exposed sides and visible gaps that an ordinary wall plate may not cover properly.
Unlike 9/16-inch deep plates with a straight 90-degree return, these covers have a broad beveled edge that slopes smoothly from the face of the plate back toward the wall. This creates a cleaner, more decorative transition while still providing additional depth.
3/8-Inch Deep Wall Plates with Beveled Edges
Our 3/8-inch deep wall plates combine additional clearance with a smooth, pronounced beveled profile. They are intended for installations where a conventional switch plate or outlet cover cannot sit neatly against the finished wall because the electrical box or wiring device extends outward.
The face of the plate projects approximately 3/8 inch and then slopes back toward the wall through a broad bevel. This deeper bevel helps cover the exposed sides of the installation while giving the plate a finished and intentional appearance.
What Is a Beveled Deep Wall Plate?
A beveled deep wall plate does not use a straight vertical side around its perimeter. Instead, the outer edge slopes gradually from the raised face of the plate back toward the finished wall surface.
This angled transition is what distinguishes the 3/8-inch style from our deeper 9/16-inch wall plates. The 3/8-inch plate provides meaningful additional depth without the box-like appearance of a straight 90-degree return.
When Should You Use a 3/8-Inch Deep Wall Plate?
A 3/8-inch beveled switch plate or outlet cover may be useful when:
- An electrical box or wiring device extends beyond the finished wall
- A standard wall plate leaves a visible gap behind the cover
- A smoother transition back toward the wall is preferred
- A kitchen backsplash or tile installation creates an unusual wall-to-box relationship
- Stone, marble, paneling, or another wall treatment changes the finished surface depth
- An existing electrical box is not perfectly aligned with a renovated wall surface
- Additional clearance is needed without using a straight-sided 9/16-inch plate
These conditions are often encountered during remodeling projects, especially when an existing electrical box remains in place while the surrounding wall, backsplash, tile, or paneling is changed.
Ideal for Backsplash, Tile, and Remodeling Applications
A 3/8-inch deep outlet cover or switch plate can be especially helpful in kitchens, bathrooms, and other remodeled spaces where tile, stone, paneling, or another finished surface affects how the electrical box and device meet the wall.
When the box or device remains slightly proud of the finished surface, a conventional plate may leave an unattractive gap. The deeper beveled profile helps conceal that space while creating a smooth transition around the plate.
The broad bevel also gives this style a more decorative appearance than a straight-sided deep plate, making it well suited for visible residential and commercial installations where both function and appearance matter.
3/8-Inch Beveled vs. 9/16-Inch 90-Degree Return
Wallplate.store offers two distinct styles of deep wall plates. Both provide additional depth, but their profiles and applications are different.
| Deep Plate Style | Depth | Edge Profile | Best Suited For |
|---|---|---|---|
| Beveled Deep Plate | 3/8" | Broad, smooth beveled edge | Moderate additional depth with a smoother, more decorative transition |
| 90-Degree Return Deep Plate | 9/16" | Straight side with no bevel | Installations requiring greater depth and a straight-sided profile |
Choose the 3/8-inch beveled style when moderate additional depth is needed and you prefer a smooth transition back toward the wall.
Choose our 9/16-inch deep wall plates with a 90-degree return when the electrical box extends farther outward and greater clearance is required.
Available for Multiple Wall Plate Configurations
The 3/8-inch deep beveled construction is not limited to one device type. Depending on availability, deep wall plates may be offered for configurations such as:
- Toggle switches
- Duplex receptacles
- Single receptacles
- Blank electrical boxes
- Block, rocker, or GFCI-style devices
- Selected multi-gang and combination configurations
Products in this collection are grouped by their 3/8-inch deep beveled construction. The same products may also appear in the appropriate toggle, duplex, blank, rocker, gang-size, material, or finish collections to make them easier to locate.
Deep Wall Plates vs. Standard Beveled Wall Plates
Many ordinary wall plates have a shallow bevel around their edges, but that does not make them deep wall plates.
A standard beveled wall plate is intended to sit close to the finished wall. A 3/8-inch deep beveled wall plate has a substantially more pronounced profile that extends farther outward before sloping back toward the wall.
This additional depth is what allows the plate to help cover a protruding electrical box, device, or visible gap that a conventional plate may leave exposed.

Frequently Asked Questions
How deep is a 3/8-inch deep wall plate?
The plate has an approximately 3/8-inch, or 0.375-inch, deep profile. Its broad beveled edge slopes from the raised face of the plate back toward the finished wall.
Does a 3/8-inch deep plate have a 90-degree return?
No. The 3/8-inch style has a beveled edge. The straight 90-degree return is used on the deeper 9/16-inch wall plate style.
What does the beveled edge do?
The bevel creates a smooth transition from the raised face of the wall plate back toward the wall. It also helps conceal the sides of a protruding electrical box or device without creating the box-like profile of a straight return.
Can a 3/8-inch deep wall plate be used around a backsplash?
Yes. It may be useful in certain backsplash, tile, stone, paneling, and remodeling installations where the electrical box or device extends beyond the finished wall surface.
Should I choose a 3/8-inch or 9/16-inch deep wall plate?
Choose the 3/8-inch style when moderate additional depth and a smooth beveled appearance are preferred. Choose the 9/16-inch style when greater depth is needed and a straight 90-degree return is more appropriate.
Is a deep beveled plate the same as an oversized wall plate?
No. A deep plate provides additional depth away from the wall. An oversized wall plate provides additional height and width to cover a larger area surrounding the electrical box.
