A tough, open style shutter that provides a high level of security while keeping a sense of open space.
The Vison Air sliding folding grille combines good airflow and visibility with excellent security. The panels in the curtain have evenly spaced holes 5mm in diameter (oblong holes available as an alternative). When lit from behind these create an attractive transparent effect.

Horizontally operated top hung sliding folding shutter.
Constructed from 152mm wide x 1.8mm thick full height aluminium panels. The panels are framed by full height butt hinges at 178mm centres. The panels are perforated by 5mm diameter holes in a 4.76mm staggered pattern and fitted with 102mm high solid aluminium plates at the top and bottom of the closure. Alternatively, they can be by 6mm x 32mm rectangular slots in evenly spaced columns and staggered rows.
The overhead track is 33mm wide x 46mm high and takes 29mm diameter roller trolleys. The rollers bear on a 7mm thick aluminium surface within the track.
Track curves, where indicated, have a 254mm or 356mm radius.
A custom radius track is also available as an option.
Optional painting to any RAL colour possible.
Push or pull, manual operation.
The grill incorporates 62mm x 33mm aluminium rectangular locking posts that are placed at regular intervals along the length of the curtain.
Posts fitted with floor bolts include a spring capped floor socket.
Lead and trailing end posts are fitted with cylinder controlled lock stiles with self-adjusting cold rolled steel floor and top track bolts.
Intermediate locking posts are generally fitted for every 3048mm of curtain.
Bi-parting curtain assemblies are supplied with a hook-bolt deadlock activated by keyed or thumb-turn cylinders. The associated slam-post is fitted with a steel floor bolt and includes a full height channel to accept the hook-bolt deadlock.
10.7 kg/square metre.
Minimum stacking is 87.5mm/metre of opening plus 89mm per locking member.
Please note: the shutter support must be able to carry the weight of a fully stacked door at any point along its length.
