Practical diamond grille style, custom made for your windows

Diamond is best suited to homeowners who want a dependable window screen with a more traditional grille appearance. It offers a strong, economical alternative to premium mesh products while still being custom made, security tested and professionally installed.

The difference is in the construction. Prowler Proof Diamond screens are welded, helping reduce visible joints and creating a cleaner finish than many conventional diamond grille products.

Strength begins at the corners

One of Prowler Proof’s strongest points of difference is the way the frame is built. Diamond frames are welded before powder coating, helping create a cleaner finish and a stronger, more durable window screen.

Toughened Welded Corners

Unlike conventional mitred frames secured with screws or rivets, Prowler Proof frames are welded into a seamless structure before powder coating. The result is a stronger, cleaner-looking frame designed for lasting performance.

  • Welded rather than assembled with screws or rivets.
  • Joined into one continuous frame structure.
  • Powder coated after welding for a seamless finish.
  • Fewer potential weak points and corrosion risks.
  • Cleaner appearance across different window styles.
