This flush mount wood floor register is designed for installation into hardwood flooring and includes both the frame and removable insert. The listed size (4x10, 4x12, etc.) refers to the floor opening/duct opening size, not the outside dimensions of the frame or insert.
Installation requires routing or cutting the flooring to accept the supplied frame. The frame is intentionally larger than the listed size so it can support the insert and cover the edges of the floor opening. This product is designed to be installed as a complete frame-and-insert assembly and is not intended to be used as a replacement insert for an existing register frame.
Please verify your floor opening dimensions before ordering. Professional installation is recommended.
NO RETURNS - Please read the description and understand the product before purchasing.
Manufacturers register insert and frame sizes are all different and not compatible.
