How do I measure to make sure I get the correct size?

  • You will need the duct size or the size of the air filter.
  • Start by removing your current vent cover. For floor vent covers, this is as simple as lifting the vent cover out of the duct. Wall and Ceiling Vent Covers need to be unscrewed to get this measurement.
  • Order the vent cover by the size of the duct.

Please click on the above image for additional Information.

How do I know what type of vent cover I need?

There are several important considerations when selecting the correct vent cover. What is the function needed? Does it need to be able to close? Where is it located? Will it be walked on or need to support weight? Here are some of our most popular styles.


Surface Mount

Surface Mount (Drop-In Style)

Most common type of floor, wall, and ceiling registers and returns.

Available in wood, metal, and resin.

Often include a damper to control the airflow on/off. To install, simply drop into your vent cover. (Utilize the included screws or wall clips for ceiling or wall installation)

Once installed, you can use foam strips or weather stripping to decrease the movement of your new vent cover fit if desired.

Flush with Frame

Flush No Frame

Flush No Frame

Flush With Frame & Flush No Frame

Flush Mount options look incredible on wood floors. They are typically wood and installed at the time of new flooring being installed or will require cutting of the current floor. We recommend professional for installation.

Measuring for Flush Mount with frame requires you to measure the duct size and order per that measurement. You can confirm the overall size of the vent cover with frame by navigating to the product page.

Measuring for Flush Mount without frame requires you to measure the duct size and the overall size of the floor opening. Order based on duct size but confirm the overall size listed on product page.

Hinged Air Returns & Air Returns

Both are available in wood, resin, and metal are often installed in wall or ceilings.

Hinged Air Returns allow easy access to change air filters and utilize latches or magnets to secure door.

Air Return Grilles are fixed and do not allow easy access to a filter.

Air Return Grilles are ordered by the duct size.

Hinged Returns are ordered by the size of the filter. (i.e. 20" x 20" filter = Order 20" x 20").

Baseboard Register

Baseboard Registers, Returns, and Covers

Available in both steel, aluminum, and wood

Typical measurements include a height of about 5" and depth it projects from the wall of about 3". This is dependent upon which style.

Standard lengths are 15", 18", and 24" and baseboard covers range from 4' - 6'. Custom sizes are available

What is the difference between a register (supply) and Return?

Supply Heat Register

Register or Supply

Registers (also referred to as a supply) are found around the home on floors, walls, and ceilings. They guide the hot or cold air flowing into your rooms. They include a damper that allows the air flow to be cycled on or off. Some dampers are preinstalled on the grille while some are mounted independently into the duct.

Hinged Air Returns

Hinged Air Return

Air returns and hinged air returns circulate the air from your rooms back to you air handler where it is filter and redistributed throughout your house. Filters are typically found in one of two placed. They can be installed at the air handler or at the air return using a hinged door, magnetic door, or a door with thumb screws. The hinged air returns provide easy access to your filter making it easy to change.

Air Return

Air returns or return grilles also circulate the air from your rooms back to your air handler where it is filtered and redistributed throughout your house.

How do I Install mounting clips?

Mounting Clips are typically used to mount the vent covers on the wall. They can also be used on the floor for an extra snug fit. Mounting clips are included with all of our Madelyn Carter™ vent covers.

They are installed by removing the damper screw, adding the mounting clip, and replacing the screw. Please see the video below for more information.

How can I avoid seeing the duct work once my new vent cover is installed?

There are a few different options. Our Steel Designs vent covers offer an optional concealment louver which is designed to hide unsightly duct work. The vent covers with a damper (registers) make it difficult to see the duct work. Many of our contractors and professionals use flat black spray paint to hide the duct work.
