Expanding Security Grilles

Doctor Locks provides purpose built expanding security grilles, manufactured in the United Kingdom, providing security with ventilation. Ideal for use in the home, office or shop environment.

  • Our discreet panels form a neat and unobtrusive ‘curtain’ when not in use.
  • Smooth and quiet operation is facilitated by nylon components which separate all steel moving parts.
  • Each bespoke grille is manufactured to meet size requirements and can be finished in any of our standard colours.
  • Galvanised steel is used to ensure all grilles remain rust-free and only require minimum maintenance.
  • The bottom tracks can be hinged up or made removable to allow easier access for wheelchairs and pushchairs.
  • Planning permission is rarely required.
  • A Multipoint locking system is designed with the user’s protection in mind, offering maximum security, including an anti-lift hook bolt which is housed in an aluminaceramic core for protection against saw attack.
  • The grilles are manufactured from an extruded aluminium framework with galvanised steel uprights and cross members, meaning they are both strong and attractive in appearance.
  • Grilles can be powder coated in various colours, allowing the grilles to blend in or stand out from the environment.

Variable Options

  • Curtains can be folded to either side (Single Stack) or both sides (Double Stack).
  • Fixed Panel: Panels can be manufactured in a fixed framework, with no lock.
  • Flexible Stack: The grille can be opened from either side and can be moved to the left or right as required.
  • Whole Stack to Hinge Aside: The curtain can be made to hinge 90 degrees, in order to allow maximum visibility and access.
