The stainless steel proofing grilles have a mesh size of 2 mm and a central bar for strength. With the GevelFix, you can fit insect mesh separately, so insects stay out too.\u003c\/p\u003e\u003cp\u003eStainless steel is the standard here: rodents chew through plastic grilles and foam, stainless steel much less easily.
