Expanding Security Grilles

The A1S Groups’ expanding gates are for higher security domestic use and medium security for commercial, retail and counter/cabinet applications. ‘X’ and ‘S’ lattice designs are optional at no additional cost.

Elegant good looks with a heart of steel – expanding gates combine a classic appearance with the highest level of protection, ideal for your home or workplace.

Designed to keep intruders out while letting maximum light in, they are perfect for patio doors and French windows and any other vulnerable ground floor doors or windows.

When not in use, these retractable gates are surprisingly unobtrusive. Fitted to the door or window surround, they can disappear neatly behind curtains and a pelmet can conceal the top track.

The A1s Groups’ expanding gates are exceptionally safe and easy to handle with a smooth, quiet operation. They hang from a top track with a guide track at the base, which can be supplied as an optional extra to quickly fold away when not required.

The opportunity to remove the bottom guide track from the opening (an optional extra) leaves domestic French windows, doorways and shop entrances free from obstruction.

Because they are fully retractable, each sash can be stacked neatly in the open position away from the door or window openings when not required, and may be hinged to swing away from the opening at 90 degrees or 180 degrees to provide a completely clear opening as an optional extra.

Installed inside a window, retractable gates deliver an exceptionally strong yet aesthetically appealing barrier against intruders, which allows merchandise to be displayed safely, 24 hours a day.
