- Two brass Slamlocks™. The design patented by Maxidor is more resistant than a classic protective grill.
- In an emergency, the two independent locks can be snapped shut without having to find the key.
- Two 13.0 mm thick uprights for extra solidity.
- Flights (diagonal attachment bars) of a design specific to Maxidor in 5 mm thick stainless steel, with the hinges protected behind the double uprights, increasing resistance to intruders.
- An aluminium track rail with strong connecting components that can better withstand an attack than a U track, as well as a curved bottom rail designed to prevent tripping.
- Powder-coated for a perfect and long-lasting finish (resistant to rust and sunlight).
