TIMESETL 5Pack Stainless Steel Woven Wire Mesh Screen, Air Vent Mesh, 11.8“ X 8.27“（30 x 21cm) 1mm Hole 20 Mesh, Metal Mesh Sheet, Rodent Mesh Screen for Garden Animal Cage Net Security Cabinets Mesh

We trimmed and used these on our rv water heater to keep bugs out. It was easy to trim with metal cutters.

The holes in these meshes are extremely small, like about the width of a sewing pin or smaller. I wouldnt recommend using it to cover any floor ac vents since it blocks out a lot of air, if the holes were like two times bigger it would be better for home ventilation.

Sturdy stainless wire screen. Used to sift with.

Started to rust after 3 weeks

Strong steal quality seems good but amount given for price is needing improved

These came and worked great for what we needed.

The material is solid and just stiff/flexible to be used in the way we need it. We split the sheet and wrap it on the stack pipe then secure it with a 5” stainless hose clamp. A full sheet works perfectly on the goose neck. We put them on 10 building roofs that has a rat issue and it has resolved the issue in all the buildings.

Sturdy. Excellent quality.

Keeps critters out of the crawlspace!

Absolutely fantastic! I needed something that would hold small items, but let water drain through, this Stainless Steel mesh was just the thing!
