Baseboard Heater Corner FAQs
Ready to install your Baseboarders heater covers? There's no need to cut corners!
If you’ve got questions about baseboard heater corner covers, check out the FAQs section below to find the answers.
Can You Explain the Different Corner Components?
Let’s go over a couple of common terms and sizing options:
90-Degree Corners:
A baseboard heater 90-degree corner is the most common corner piece you’ll encounter. That’s because most corners in your home or office intersect at a 90-degree angle. Many 90-degree corner covers are shaped like the letter L with a longer front piece and a shorter piece that meets it at a corner.
135-Degree Corners:
A baseboard heater 135-degree corner is a less-common piece compared to 90-degree corners. You’ll usually need this corner for bay window placements or other specialty areas that aren’t 90 degrees.
Inside Corners:
Inside corners meet at an angle that points AWAY from the room.
Outside Corners:
Outside corners meet at an angle that points TOWARD the room.
Couplers:
Couplers join two panels together for longer lengths. They overlap, and hide, the seam that two panels create when they are butted up together.
Wall Brackets:
Typically used when the original backplate has been removed, when the original backplate is less than 7.5" in height (less than 9.5" for Premium Tall), or in new construction environments.

How Do I Measure for Baseboard Heater Corners?
After you've removed the endcaps and front panel pieces, it’s time to begin the measuring process. Here’s how to measure each corner cover type:
90-Degree Inside Covers:
-
Measure the first unit from the pipe on the far end all the way to the adjacent wall in the corner.
-
Subtract 3 inches from this measurement.
- Measure the unit on the opposite wall using the same instructions in steps 1 and 2.
Do your 90-degree inside corners form a U shape? The measuring process varies depending on the application:
-
Middle Panel Applications: Subtract a total of 6” from the wall-to-wall measurement since this panel will be fitting within an inside corner piece at both ends.
- Applications Where Two Panels Meet: Subtract 3” from each location where the panels meet.
135-Degree Inside Cover Units:
-
Remove the endcaps and front panels of the heaters that are meeting in the bay window corners.
- Once you’ve completed step 1, measure from where the front plates meet, usually located 2.5" - 3" in front of the back plate.
90-Degree and 135-Degree Outside Cover Units:
Measure from the far end of the application to the point where the two walls meet at the outside corner.
Note: There is no need for deducting 3” from the measurement since the outside corner piece attaches differently than the inside corner piece. The outside corner piece will extend beyond where the walls meet and clip to the end of the panels.
How Do I Install My Baseboard Heater Corner Covers?
After you’ve picked out the right covers and completed any measurements, it’s time to install. Here’s how to install each corner type:
90-Degree Inside Cover Units:
-
Install panels on both walls.
-
Starting from the bottom of the panels, place the small metal piece located at the bottom of the inside corner piece underneath where the two panels meet in the corner.
- Move the inside corner piece upward to secure the clip (located on the right side) over the top of the panel.
135-Degree Inside Cover Units:
-
Install panels on the wall.
-
For attaching the corner piece, start at the bottom of the panel and place the angled piece of the shaft underneath where the panels meet in the corner.
- Next, move the inside corner piece upward to secure the clip (located on the right side of the corner piece) over the top of the panel.
90-Degree and 135-Degree Outside Cover Units:
For 90-degree and 135-Degree outside cover units:
-
The outside corner piece will extend beyond where the walls meet and clip to the end of the panels.
- Every other step is the same as the inside cover unit process.

Do I Need to Worry About Backplates or Brackets?
Your backplate is a piece of metal that’s attached to the wall behind your baseboard heating unit. Our Baseboarders® heater covers are designed to slip over your existing backplate, so you don’t need to purchase a new backplate if you already have one installed.
If you don’t have a backplate, you’ll need to purchase a wall bracket for the new cover to sit on.

Does It Matter Which Style of Cover I Get If I Have Corners?
Our Basic, Elliptus, Premium, and Premium Tall styles are equipped to handle corner installations. Just make sure to include any additional corner components (end caps, couplers, brackets, etc.) to fit the panels.
Does My Baseboarders Order Come with Couplers for the Corners?
Couplers are sold separately and can be found at the link below.
Do I Need to Order Special Corner Covers/Couplers?
No special cover is necessary. All you need are the endcaps, couplers, and corner pieces. Just make sure they’re all in the same style and match the layout.
Keep in mind, these items are all sold separately from the cover.
Can I Order the Covers Pre-Cut?
Custom cuts are available on every cover style. You’ll choose your sizing option under the “length” section on the product page.
Should I Cut Both Lengths of the Cover Short Where They Meet in the Corner?
Since the outside corner piece attaches differently than the inside corner piece, you don’t need to cut your corners short. The outside corner piece will extend beyond where the walls meet and clip to the end of the panels.
