Diamond Grille

At first glance Prowler Proof’s Diamond designs look similar to other security screens.

But have a closer look. You’ll soon notice that there are no visible joints – it looks and feels like the security screen is made in one piece. Which is not far from the truth. Prowler Proof’s security screens are not held together by screws or rivets, they are welded. This adds strength… and good looks.

You can choose between the Small Diamond and the Large Diamond designs. Both are secure and economical – Small Diamond marginally more secure, Large Diamond marginally more economical. Both options are available as SnapLock – a unique production process that makes it possible to choose any colour frame to match a black mesh. Looks fantastic!

Welded Diamond - Small

With smaller openings in the mesh, Welded Small Diamond is even more secure than Welded Large Diamond. Apart from that the two styles are identical. The frame and the mesh are both the same colour...you have 300 to choose from.

SnapLock Diamond - Large

With the same performance as Welded Large Diamond, the SnapLock Large Diamond is a unique product that allows you to match any colour frame to its black mesh. Black mesh is more transparent and blends in better with the look of most homes.

SnapLock Diamond - Small
