Sierra Grates Floor Registers & Grilles

Sierra Grates is a partner brand offered by FLI Products for floor register and grille options. Compare the selected product’s style, material, finish, dimensions, and installation requirements to choose a cover for your opening.

Measure the Opening First

Measure the duct opening, not just the outside of the existing cover. Compare those measurements with the listing’s specified opening size and overall cover dimensions. Check insertion depth and clearance around trim, flooring, furniture, and any controls.

Confirm Register or Grille Requirements

Check whether the selected product is a register with airflow controls or a grille without them. Choose the appropriate type for your system and location. A new cover does not guarantee improved airflow or resolve an HVAC problem; consult an HVAC professional when system suitability is unclear.

Compare Styles & Materials

View Sierra Grates Contemporary and Sierra Grates Metro. Review each listing for its actual material, finish, available sizes, and installation details. Do not assume every product shares the same construction or exposure suitability.

Installation & Care

Follow the selected product’s instructions and verify fit before installation. Do not assume every opening accepts a drop-in replacement without adjustments. Check the product’s intended location and load guidance rather than treating a vent cover as suitable for unrestricted foot traffic.

Follow the finish-specific cleaning instructions. Do not assume a finish is rust-proof or suitable for wet locations.
