The MicroCoil Extreme300 Series Grille is ideal for parking garages with limited headroom and ADA compliant facilities.

The SmokeShieldElevator Closure is the most design adaptable hoist way smoke curtain in the industry. By sealing in front of the elevator, the curtain makes it possible to eliminate the IBC elevator lobby requirement, giving the freedom to design an open a space that would otherwise require an elevator lobby.    

The SteelWeaveMetal Mesh Grille complements and enhances any buildings design while still providing security. It features a durable type 316 stainless steel curtain that comes in two standard curtain designs and three special order curtain design. In addition to an aesthetically pleasing security grille, it is also ideal as a room or space divider.
