Steinberg14 Beige/Oak Door Vent Cover 17.7x3.6 inch with Screws - Plastic Ventilation Grill - Door Vents for Interior Doors Two Sided - Door Louver Vent - Door Return Air Vent with Screws

Perfect product! I only wish more different colors were available.

One customer asked if it lets light through so i thought a pic might be helpful. We installed this vent on our laundry room door because the HVAC unit was loud but with door closed it was creating a strong vaccume and needed more airflow to not stress unit. We installed 3 of these vents into the door reducing the noise dramatically while still allowing adequate airflow.

They're solid enough and will function as intended, air flows through without looking like a hole in the door. I ended up getting the one without screws and used #6 by 1.5" wood screws. They're easy enough to install if you have any experience with a jigsaw and a drill. It would be nice if they came with a template, but being square its easy enough to just measure and mark up the door that way.I wish they were a little less glossy, but otherwise I'm happy with the way they look and fit my doors.

Manufacturing Defect: One of the bosses for the mounting screws had no hole for the screw. Design Shortcoming: The flange at the edge that best serves as the top extends past the body by only 5 mm, which means you need to be really careful to cut an accurate opening when cutting the hole in the door. The opposite edge and the ends are much better with the flange extending 9 mm past the body.My measurement of the body/minimum opening size is 432 mm by 77 mm. There are three screw lengths provided. The screw head type is #1 posidrive.

This event worked perfect in the door. I needed to put it in. Great quality for the money.

Perfect!!!

Very easy to install. Placed it in a bedroom door that has to stay closed. A/C unit needed to draw air for return. Vent worked very well.

The thickness of my door is 1-5/16" (1.31"), but the screw came with is a bit short that cannot use to hold the air vent grill.
