How to Check Compatibility

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

    Measure Height from the Floor

    Remove end caps and front panel. Measure from the floor to the top of existing back plate. Measurements 7-1/2"- 8-3/4" require standard height styles. Measurements 9" - 10" require Premium Tall. Note: Standard height endcaps are 7-1/2" tall. Premium Tall endcaps are 9-1/2" tall. Measurements less than 7-1/2" or between 9" - 9-1/4" require wall brackets for installation. Wall brackets will raise the overall installation height by 1-1/4".   
  • Step 2:

    Measure Height of Heater Unit

    Measure from the bottom of finned heating element to the top of existing back plate. This measurement is typically 5" - 6-3/4" with standard installations. With a 7-1/2" overall installation height, there will be a 3/4" space between the floor and bottom of the replacement cover. The space between the floor and bottom of the heating element must be a minimum 3/4" to keep the fins from showing beneath the replacement cover.
  • Step 3:

    Measure Depth

    Measure from the wall out to the front of finned heating element. Measurements deeper than 3" require the new cover to be installed using a piece of wood moulding, along with our wall brackets, to accommodate the heater depth. Max inside depth of Baseboarders™ panels is 3 inches.

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.
