Custom Engraving Fee

1. Remove existing vent covers
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
2. Measure the hole
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.

kül grilles - Technical Specifications

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.

We have two damper options available:

• Slide damper (available for 10x3, 10x4, 12x4)
• 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).

To add dampers to your grille, please contact support.

Slide Damper (Optional)

To maintain a minimalist appearance, kül offers a visually clean, easily accessible residential slide damper as an accessory to our linear grilles to allow for air flow control where necessary. Available for our standard 10x3, 10x4 and 12x4 grille sizes, these dampers are stock items and are available for quick ship.

Opposable Blade Damper (Optional)

kül offers a quality coated steel construction opposed blade damper as a custom accessory to our linear grilles. The gang operated damper blades move simultaneously in opposite directions for smooth volume control from fully open to fully closed and can be manufactured for almost any standard size of kül grille.
