Register Sizes and Installation
Replacing your old floor registers and air returns is easy. All of our registers are listed on our site by air duct size, which is the industry standard. We also provide the overall dimensions for added convenience. These are particularly helpful when measuring for flush mount registers; please consult the product page for exact dimensions.
Register Plate Configurations
Here's how to find the correct register size. Note: Flush-mount registers will fit completely into the floor with no lip. See product page to check duct measurements and overall size.
Step 1: Measure the length and width of the actual opening in the floor. This will determine your register size.
Step 2: Fit the register into your floor. The louver frame or bottom part of the register will fit into the opening, while the lip of the register will sit on top of the floor.
Wall Register and Air Return Directions
Step 1: Measure the length and width of the opening in the wall. This will determine your register size.
Step 2: Mount the wall register either by tension-fitting or by securing provided screws in the front lip. See product pages for details on specific registers.
