Before you Begin:

Flush mount registers require a certain skill level to install and are targeted towards contractors and skilled

DIY enthusiasts. Please consult a professional if you are unfamiliar with installing hardwood fixtures.

Decor Grates is not responsible for damage to your home, product or person.

Staining Unfinished Flush mounts:

If you have an unfinished flush mount, ensure that you are not applying stain, paint or lacquer to the

plastic damper box. The damper box can be taken off by removing the screws. When replacing the screws

do not over tighten as it can cause damage to the damper box and/or grate.

Step 1: Position the entire flush mount (frame with

the grille and damper box) over the opening to ensure

that the damper box will slide freely into ductwork

opening once completed. Ensure your flooring and

frame are the same depth. If not, shim the frame

accordingly to match your flooring. Tack it into place

using nails or glue.

Step 2: Once the frame is affixed to the sub floor,

measure and lay flooring around the frame work. If

the flooring installed is tongue and groove, the tongue of

the flooring will fit into the groove of the frame. Please

note that Decor Grate flush mounts are designed to fit

with a standard ¾” flooring tongue. If flooring installed

is not tongue and groove, butt the flooring directly

against the side of the frame and tack it into place with

nails on an angle to not interfere with the vent opening.

Step 3: Insert the grille into the frame.

Step 1: Place the entire flush mount (frame with the grille

and damper box) over the opening to ensure that the

damper box will slide freely into ductwork opening once

completed. Trace the outside of the frame to your floor.

Note: improperly sized duct openings may require resizing

to accommodate damper box.

Step 2: Drill pilot holes into each of the four corners of the

flooring that you will be removing. Do not cut or drill outside

of the traced area. Cut out the floor using a router or other

appropriate cutting tool along the lines. Remove any lose

pieces of wood, debris or obstructions to ensure the frame

sits flush on your sub floor. Underpadding or shims may be

required to match your floor level.

For installation while laying out an existing floor

Step 3: Once the frame is flush, affix the frame to the sub

floor using one of the following fasteners:

• Glue: Ensure that the glue used is compatible to the

material of your sub floor

• Nails: At an angle, drill pilot holes in the inside of the

frame, then insert nails through both frame and sub floor.

Ensure nails are long enough to penetrate the sub floor.

Step 4: Insert the grille into the frame.
