At first glance Prowler Proof’s Diamond designs look similar to other security screens. Have a closer look. You’ll notice there are no visible joints — the door looks and feels like it’s made from one piece.

The Diamond design is secure and economical — and available as SnapLock, a unique production process that lets you pick any frame colour to match a black mesh. Looks fantastic.

A closer look
Quality of manufacture and focus on the small details — that's what sets Diamond apart.

Every corner is fully welded — stronger than screws or rivets, and it looks like the door was cut from one piece.

Traditional diamond-grille pattern — a strong, economical security alternative with the classic look that suits every era of home.

The grille partially obstructs the view but still allows excellent airflow — ventilation without compromising the security envelope.

Australia’s only full 10-year replacement warranty on every product. If it fails, you get a brand new one — no ifs.

Colour range
All Prowler Proof Diamond doors come in 50 standard colours, with another 250 optional colours available. There’s no extra delivery time — and only a small premium — for optional colours.

Australian Standard AS 5039
The Diamond design passes the AS 5039 security test with ease. The 1,000-hour salt-spray tests (AS 2331) aren’t much challenge either — conducted at +35°C, near-100% humidity, in a solution saltier than sea water. You won’t find a stronger diamond-design security screen door on the Australian market.

Six separate tests passed by the same sample: dynamic impact, jemmy, pull, probe, shear and knife shear. Diamond passes with ease.

Bushfire-prone zones need corrosion-resistant mesh with openings under 2×2 mm (AS 3959-2009). The fire-attenuation test (FS 4302/3572) shows the reduction in radiant heat flux.

AS 2331.3.1 (neutral) and AS 2331.3.2 (acetic acid) salt-spray tests, 1000 hours in an enclosed chamber saltier than sea water. Diamond comes out unphased.

The mosquito protection test measures ability to keep mosquitoes out over extended periods. Diamond’s aluminium grille + optional insect gauze passes.

NCC (BCA 2013) requires certain window openings to be screened to prevent child falls. Diamond resists a 250 N outward horizontal action — window restrictors can be removed.

Optional accessories: keying locks alike, pet doors, port holes and hopper hatches. Tested for consistent unassisted access.

We recently had a front security screen door installed by Advanced Security Doors and couldn't be happier with the result. Corey was not only highly professional and knowledgeable, but also one of the friendliest people you could hope to deal with. His genuine, approachable nature made the whole process a pleasure, and his advice helped us choose the perfect product for our home. The installation was smooth and efficient, and the finished door looks fantastic. We wouldn't hesitate to recommend Corey, Jonessa and the team for their exceptional service and quality workmanship.

Corey has been amazing throughout the quotation and install process. With a competitive quote for the product quality, it was installed in under 3 weeks from the initial quote. On the install day, Corey was here for under an hour and even had to grind off some of our molding to enable the door to open. He politely asked and made it look very intentional and part of the initial build. It's changed the aesthetic of the home and allows for so much light into the home, while keeping our loved ones safe. Appreciate it Corey, highly recommend!

Corey was brilliant!! I recently had three security screen doors fitted to my new home. I chose the Prowler Proof doors with Forcefield mesh and they DO look great (the advertising was true - the welded corners look much better than jointed riveted frames). While slightly more expensive than other quotes it really seemed worth it for that difference. As a bonus, Corey was genuinely a pleasure to deal with... Knowledgeable, always friendly and helpful, as well as super fast and efficient when installing the new doors. Besides looking great, the doors also fit perfectly (closers included). I really appreciated his updates on the progress of my order, and the fast turnaround time on manufacturing. I will definitely be ordering more doors in future from Corey (I have two doors on an outbuilding that also need screens). Highly recommended.
