Getting the right size is simple. Measure your duct opening and match it to our chart below.
Carefully lift and remove your existing floor register from the duct opening.
Using a tape measure, measure the width and length of the duct opening in your floor. Measure the hole itself, not the old register faceplate. Record as Width x Length (e.g., 4" x 10").
Find your duct opening dimensions in the size chart below. The faceplate will be slightly larger to overlap the opening and sit flush on your floor.
All dimensions are in inches. The faceplate is the visible portion that sits on top of your floor.
