S04 Expanding Security Door System
S04 Expanding Security Door System
The S04 security door system is ideal for keeping your business safe because of its strength and functionality.
Why should I choose the S04 for my business?
- Flexibility
There are S04 steel expanding grilles to fit any size openings. All S04 grilles are up to two and a half metres high, and can lock either left or right. All you need to measure is the width. S04 grilles can be fitted to the inside or outside of existing doors and using adjustable posts at intervals for support means you don't need top supports or tracks. - Unobtrusive
The S04 folds up to only 15 % of its open size, and folds neatly out of the way when not in use. (Unique hinge aside pivoting facility). The S04 does not require a floor track so your customers will not be obstructed. - Cover Large Openings
The S04 grilles will be made to any width by joining various sized grilles together. These can be self-supported (no floor or ceiling track) or hung from a ceiling track. Adjustable posts are available for supporting large S04 grilles when only half the opening is required to be secured. - Long Lasting
The S04 grille has been treated, epoxy powdercoated and galvanised against corrosion. - Unique Hinge Aside Pivoting Facility
