Custom Capabilities — Make Your Vision a Reality
Jun 10, 2026
Custom grilles are a key part of our product offering. Beautiful spaces often require custom designs. Our custom quoting and sizing offers Builders, Architects and Designers the ability to make the grilles work within the design, not the other way around. Our custom air vent covers align perfectly with your vision.

Solutions for Every Challenge
Whether you have a fireplace installation, a long, linear architectural installation or a custom size you just can’t find – we would love to work with you on your next custom challenge!
Proper measurement is crucial for the perfect fit for your new kül grille. Our vent cover measuring guide is designed to assist you in this process and make it as straightforward as possible. First, you’ll want to remove the old vent cover or return cover and secondly, measure the height and width of the duct opening twice to ensure accuracy.
Once you have your measurements, you can select a standard vent cover size or try our online quote tool for custom sizes and/or larger projects to get everything you need all in one convenient place.
For any specific question or challenges, contact one of our product specialists. We will guide you through the process, ensuring that your size, design and color preferences are met with precision and attention to detail.
Designed to blend functionality with modern elegance, kül grilles provides a reliable custom solution for homeowners and designers seeking the perfect air vent covers to suit any architectural need.
