It’s almost invisible, still it’s near impossible to get past. Like all other Prowler Proof products, ForceField® is welded instead of being held together by screws or rivets. A weld is stronger than any screw or rivet…and it looks better too. With its seamless corners, ForceField® is the best looking security screen on the market. The assembly system is patented and unique to ForceField®. The heavy duty aluminium frame and the marine grade stainless steel mesh are joined together in a mechanical and chemical bond. It is virtually unbreakable and provides complete insulation of the two metals…eliminating a major cause of corrosion. ForceField® has passed every imaginable test – and a few you would never imagine.

Prowler Proof ForceField® has passed every imaginable test…and a few you would never imagine. The standard security tests almost seem trivial compared to being hit by 5 steel balls less than a centimeter in diameter at 170 km/h plus. Or by a 4 kg timber block at more than 100 km/h. You are safe behind a ForceField® security screen.


All Protec products come in 50 standard colours and another 250 optional colours.
