Roller Pull Down Window Mesh

This system rolls up and down into an aluminum section when operated. It can be pulled down and locked at the bottom end. It can be rolled up to the top conveniently.In short, you should use knotted netting for windows if you are trying to protect yourself from mosquitoes. For all other types of bugs use braided netting if you are trying to protect yourself from either of the two. For the tightest weave and best protection against all types of bugs, choose continuous filament mesh.
