Tip: Do NOT measure the old vent cover. Every vent cover has a different size of outside frame so we cannot use the old/existing vent cover as a guide
Tip: For custom sizes, please send us the exact dimensions of the hole. This helps us determine which size works best. (do not undersize the dimensions)

*Requiring mounting holes for ceiling and wall applications? Check out our more detailed measurement guide here.

Powder Coat Finish
- Glacier Frost, Black Monolith, and Wenge Brown
Powder coat is an applied powdered form of paint that is baked onto the vent cover for an extremely durable, yet attractive finish. Common applications of powder coat include coating of cars, gym equipment, and even aircraft components.
Anodized Finish
- Anodized Clear and Anodized Light Bronze
Anodizing is a process that forms a protective layer from the original metal resulting in its matte appearance. Example applications of anodizing are in common electronics within microchips.
Brushed Chrome Finish
The brushed chrome process consists of raw aluminum being carefully brushed and slightly buffed to create a linear metallic finish across the face of the vent cover.

Question: Do you have dampers or a way to regulate airflow?
Answer: Yes, we have two damper options available, a slide damper (available for 10x3, 10x4, 12x4) and an opposable blade damper (can be manufactured for any size). We do not ship our standard vent covers with dampers (Maximum airflow is important, so we only provide dampers on request for rooms where airflow control is required).
Question: When are dampers required?
Answer: Dampers are typically required to close off airflow to specific areas. (Bathrooms, bedrooms), depending on the climate. Some of the newer and higher end HVAC units have damper mechanisms inside the duct work that can be controlled from the HVAC unit
Question: What is the depth of your grilles?
Answer: Our grilles recess 1” into the duct/hole opening
Question: How large can custom grilles be made?
Answer: The maximum height we can make is 24” and the maximum length in a single piece construction is 72” (6ft) we can make unlimited lengths, however anything over 72” will be provided in multiple sections with supplied alignment plates to join the sections with a continuous appearance with mitered corners on the outside sections.
Question: How durable are your grilles?
Answer: Our grilles are manufactured from extruded aluminum and re-enforced tig welded, so they are durable, but they are not rated for heavy traffic applications. The powder coat finishes are more durable than the anodized finishes and are more scratch resistant for floor applications
Question: What materials are kul grilles made of?
Answer: kul grilles are made of quality aluminum, all metal construction and are manufactured in North America
Question: How are the grilles installed for a sidewall/ceiling application?
Answer: Mounting holes are required for side wall and ceiling applications. Countersunk screw holes are predrilled into the frame of the grille and matching finish, flush mount screws are provided with each order.
