How to Check Compatibility

This is an important step to confirm that your existing finned tube element will fit our baseboard cover.
  • Step 1:

    Measure Height from the Floor

    Remove end caps and front panel. Measure between the finished floor and top of the baseboard heater. Baseboarders® products fit measurements between 7 1/2" to 10".

    For measurements between 9"-10", use the Premium Tall style. Height measurements of less than 7-½” will require mounting brackets. Mounting brackets will add 1-¼” to overall installation height.
  • Step 2:

    Measure Height of Heater Unit

    Measure from the bottom of the finned heating element to the top of the unit. Baseboarders® standard products fit measurements between 5" and 6 3/4". Less than 5" requires a mounting bracket. If greater than 6 3/4" and the height from the floor to the top of the unit is 9-10" use Premium Tall.
  • Step 3:

    Measure Depth

    Measure from the back plate to the front of the finned heating element. Measurements larger than 3" will require the new cover to be mounted using a piece of wood moulding along with our wall brackets, to give greater depth.

How to Measure Panel Length

Measure each length you need. Every time your heater turns, take a new measurement. See configuration measurement instructions next.

Measuring Notes

Here are a few tips and tricks to help your measuring come off without a hitch.
Measuring Without a Back Plate
Standard straight lengths are measured from one end of the back plate to the other. If a straight section is missing the back plate, measure from one extreme end of desired coverage to the other extreme end of coverage. Then subtract 1″.

Lengths Longer than 7'
Baseboard heaters longer than 7′ (6′ for Basic series) will require the use of multiple panels and couplers to achieve full length. We recommend that you split the length evenly between multiple panels.

For instance, an 8′ length requires two 4′ panels and a coupler. A 15′ length requires three 5′ panels and two couplers. A length of 9′-7″ requires one 5′ panel and one 5′ panel CUSTOM CUT to 55″, or two 5’ panels both cut to 57-½” for a balanced look. We will custom cut down to your specifications at no charge.

When You Need to Cover a Couple of Extra Inches
Baseboarders® are designed to yield an incredible amount of flexibility. Each endcap can be slid out up to 1-¾” to cover extra space beyond the regular length of the panel on a typical straight heater.
