Optional Underside Lip

When do you need an underside lip?

If the grille is being used for a floor installation, then you may choose an Underside Lip to hold the grille in place. If you choose it without an Underside Lip for floor installation, then you need to either (1) recess the grille into the floor so it’s flush with the floor or (2) get the grille with mounting holes to hold it in place.

If you choose an Underside Lip for a floor installation, do you still need mounting holes?

If you choose a grille with an Underside Lip, you may still want mounting holes. In high traffic areas, mounting holes keep the grille securely in place. Mounting holes also deter children from lifting or removing the grille from its opening. Mounting holes are not required for grilles with an Underside Lip (for floor installation), but may be preferred.

When is an Underside Lip for floor installation not recommended?

An Underside Lip is not recommended when your opening is not evenly cut, as an Underside Lip may not fit

3/4" Underside Lip
No Underside Lip - Flat

Optional Louver - Air Control

Air Control - Louver Basics:

These louver assemblies are designed to fit behind our grilles to control air flow and increase heating and cooling efficiency. Mounted independently of the grille, they are opened and closed with a flathead screwdriver, provided by the customer. In some cases, you may have to remove the grille to adjust louvers. Allow 2 5/16" clearance for louvers behind grille. Foam strips for installation are included with each louver.

  • Louver Installs Directly in Air Duct
  • Open & Close Louver Using Included Key or flathead screwdriver.
  • Does not direct air flow
  • Includes Foam Strip for a snug fit
  • Does NOT Attach to Grille

    Imperial Design Vent Covers

    Published by Joseph Engum on Nov 10, 2020

    I was surprised how heavy they are. I could have ordered a less robust size as it is being used as a ceiling vent, but now we will be ordering vent covers for our floor registers.

    Mostly nice

    Published by Nancy on Sep 08, 2020

    The design and weight of the cover is great. It is heavy duty and well made and it fit perfectly in my duct vent hole. I ordered the silver and was expecting a shiny silver color, however the color is more of a bluish grayish color and the finish is not shiny at all. There is also a little blemish in the finish. I thought it might have one of those transparent blue films that you often find on appliances to protect the finish in shipping, but neither my husband or I could see where there was a film that needed removed. It still works in my bathroom, but I was really looking for a shiny, not matte, finish. I guess that's one of the challenges of buying things online.
