4 Leaf Telescopic Automatic Door

Automatic Telescopic Door Operators

Automatic telescopic door operators provide an effective solution for projects where maximum clear opening width is required but space is limited due to structural or spatial constraints.


By utilising a telescopic configuration, multiple door leaves stack within a reduced pocket, delivering up to 30% greater clear opening compared to conventional automatic sliding systems. This makes them particularly suitable for restricted façades, retrofit applications, and high-traffic environments where accessibility is critical.


Designed for commercial and public access environments, telescopic automatic door operators support smooth, low-noise operation and long-term reliability for both new installations and retrofit projects.


Their compact operation ensures maximum access for wheelchairs, trolleys, and pedestrian traffic makes them ideal for narrow building façades, high footfall entrances, accessibility upgrades and sites with structural limitations.


Telescopic door leafs are supplied in a range of formats to suit project requirements:


  • Single telescopic (2-leaf)
  • Bi-parting telescopic (4-leaf)
  • Extended configurations (3–6 leaves) for wide-span openings
