Frequently Asked Questions & Answers

A register is a complete unit with a cast iron louver attached to allow control over the flow of air. If you don't see a register in the size you need simply combine a louver assembly and grille to create your own custom register.
The reference to holes refers to the screw holes for mounting the grille. When installing into a wall or ceiling you need screw holes, while with a floor application it's your preference. Many customers use screw holes when installing on carpet because the carpet is often too thick and the lip of the grille doesn't catch in the opening. Other customers use screw holes to prevent children from lifting the grille out of the opening.
Yes. If the inside measurement on the grille you're looking at is listed as 10"x 4" you can cut your hole 10"x 4" and the lip will fit into your opening. For more information about measuring please see our How to Measure page.
Aluminum grilles are most often used in wall or ceiling applications because they are lighter in weight. Aluminum grilles are also rustproof and therefore perform better in moist locations.

Our grilles are manufactured in different ways. All of our scroll designs and some of our square designs are castings made with a lip on the back that ranges between approx. ¼" to ½" deep which fits into the ductwork. The border that runs around that lip and sits on top of your opening is approx. 3/16" thick. Many of our square design grilles are made from 3/16" sheet aluminum or steel with no lip on the back.
Yes. All cast iron, brass, aluminum and steel grilles can be recessed into the floor but only during a new construction or modification of an existing hole. We recommend you wait to receive the grille then use it as its own template.
We can and do make custom sizes especially in wood and in our square design steel grilles. Please contact us for a quote and production schedule.

Approximate delivery time for custom wood orders is 4-6 weeks. Please contact customer service at 1-800-880-3090 to tell us what size you need and what type of wood you are interested in.
Louvers do not attach directly to the grille. All louvers tension fit into your opening and come with a foam outer strip to prevent damage and ensure fit. You just push the louver into the boot of the duct and place the grille on top. The grille will sit on top of the opening but not connect to the louver. A key is included that fits through the face of the grille and allows flow adjustments.
Yes, our grilles can be used outside. We recommend the aluminum grilles for outdoor use because they are rustproof and fare better in moist environments.
