Stainless Steel Ventilation Grilles with Insect-Proof Mesh

Selling brand-new stainless steel ventilation grilles, never installed, featuring stainless steel rivets and insect-proof mesh on the interior side. Selling because they are surplus from a construction project and I currently have no need for them. Dimensions are as follows: - One measuring: 40 x 21 cm — price = €25 - Another measuring: 20 x 20 cm — price = €15 - Two measuring: 19 x 15 cm — price = €25
