What We Carry

Our inventory includes supply registers with adjustable dampers, sidewall and ceiling diffusers, return air grilles, floor registers, and baseboard registers. We stock common sizes from standard residential dimensions to larger commercial openings. White is our most popular finish, but ask us about additional color and material options.

Getting the Right Size

Register and grille sizes are measured by the duct opening, not the outer frame. Measure the opening in your wall, floor, or ceiling where the duct connects and bring those dimensions in. Our team will match you with the correct register or grille. If you are building new or adding a vent, we can also help you select the right size based on your duct layout.

Frequently Asked Questions

What is the difference between a register, a grille, and a vent?

A register has an adjustable damper that lets you control airflow. A grille is a fixed cover without a damper, typically used on return air openings. “Vent” is a general term that can refer to either. When in doubt, bring in the old one or a photo and we will help you find the right match.

Do you carry custom sizes?

We stock all standard residential sizes. For unusual dimensions, give us a call at 214-340-9421 and we can check availability or discuss special-order options.
