Vent Systems 8" x 4" Inch Black Metal Vent Cover - 2 Pack - Louvered Duct Grille with Mesh Screen - Heavy-Duty Wall or Ceiling Ventilation Grill for HVAC Exhaust in Bathroom, Garage - Home Improvement

These worked well where they were small such a better quality than bought local. Thank you.

These work perfectly on our shed. We found we needed the air exchanged below our shed to keep it from molding from the ground. We didn’t have a lot of room and these are small. They have bug and mouse proof screens so they work perfectly. We appreciated that they came in brown and matched the aluminum flashing and we didn’t need to paint them.

Smaller than I thought. Although they give the dementions I imagined them larger

The small lip makes this much more rigid versus the flat stamp sheet metal ones. and it comes with a bug screen too.

I usually expect a few crews with any fixture I purchase.

easy to put up

Just what I needed. Worked out well

Does what it's made to do.
