3.Pre-Purchase Checklist

Take down your existing vent cover and measure your duct opening.Confirm the duct cavity fits the insert neck (9-13/16"W x 3-15/16"H x 1-3/4"D). Watch out for blocking wall studs or sharp tapers that prevent full insertion.

Double-check the 11-13/16"W x 5-7/8"H faceplate can fully conceal your duct opening.If old mounting marks exceed the faceplate,use touch-up paint.Make sure mounting screws fasten firmly to the duct's inner edge.

4.Our product features concealed screw mounting, supplied with 4.5×50mm self-drilling screws. We recommend using an extended Phillips bit for installation.

5.Install screws at ≥45° away from duct openings to fasten into walls instead of duct edges. Pre-drill holes then use a long drillbit simplifies installation.

6.Air flowing through ductwork naturally creates soft low humming sounds.A loud whistling noise signals airflow issues:

(1)Confirm your HVAC unit operates within standard working parameters. (2)Open additional vents to balance system airflow. (3)Use the adjuster to fully fold this grille's adjustment blades for maximum air passage.
