Reliable air distribution starts with the right hardware
Air distribution components like grilles, registers, and related hardware are among the most visible parts of an HVAC system — but they also play an important role in airflow delivery, aesthetics, and system performance. F & L® aluminum products are engineered for durability, clean lines, and professional-grade installs that stand up to daily use.
Whether you need supply registers, return grilles, adjustable louvers, or mounting hardware, selecting the correct size and style helps ensure balanced air distribution and a finish the homeowner notices for all the right reasons.
If you’re unsure about sizing (especially in multi-room systems), we can help confirm measurements so you get the right fit the first time.

F & L Grilles & Hardware — FAQs
How do I size supply registers?
Match the rough opening size and ensure the register’s free area aligns with system CFM recommendations for balanced airflow.
What’s the difference between supply and return grilles?
Supply registers direct conditioned air into spaces and often have adjustable louvers; return grilles cover the return opening and may include filters.
Can you help match hardware?
Yes—share rough openings, application (supply/return), and style preference so we can recommend the correct grilles and registers.
