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 were having roach and bug problems and had a feeling it was coming from the air vents so we ordered these and wow, they’re so cool! I have already recommended it to my friends and family. My boyfriend installed them and while it wasn’t the fastest or easiest thing ever because you have to shape them to your air vent, they are super customizable, bendable, easy to cut and once installed it does not affect airflow at all. My boyfriend actually enjoyed installing them and we’re extremely impressed by the quality. Best of all, the bug problem is gone!

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.

These came and worked great for what we needed.

Sturdy. Excellent quality.
