MY MIRONEY 10PCS Air Vents 2Inch(53mm) Black Circular Soffit Vent Stainless Steel Round Mesh Hole Louver Vent for Kitchen,Bathroom,Cabinet,Wardrobe and Shoe Cabinet

These are 1000% metric. Don’t drill your holes before getting these. These are too small to properly fit in 1 inch holes. Use a 25mm or 15/16’s bit instead.We had to line these with about 4 passes of duct tape strips to get them to fit into one inch holes.Good looking sturdy items, but don’t advertise them as fitting in one inch holes, they are too small.

I am extremely disappointed in this product, I was expecting the product to be a tight fit inside a 2 inches hole saw hole but they are way larger than 2 inches.Update 10 Mar. 2021: I found a 53mm hole saw and it fits perfectly in very thin materials, do not expect it to stay put in thicker than a 1/4 inch due to the limited height of the lip.

We have a 1995 Starcraft Islander and popped holes for these in our cuddy cabin storage and bait storage. We used to jave to constantly prop these areas open for ventilation, now with these vents we can close the lids and it still is aired out! If you have the round hole cutting attachments for your drill, these are easy to install.

Ordered a pack of 10- 1" vents.Received 1 vent in an envelope.Drilled a 1 " hole to install.This vent is smaller and does not secure in 1" hole.

Perfect for my application. Making a drying cabinet for sonic cleaned reloading brass cartridges. These are exhaust vents for hair dryer powered dryer. Look cool too.

2 of these back to back will fill a 1/2" Gives a finished look.

These parts give ventilation holes a nice finished look at low cost and are easily installed.

Nice fit as advertised
