Security Bars & Grilles for Windows and Doors
Boorer Lock & Safe supply and fit security bars and grilles to windows and doors — collapsible where you need the opening back, fixed where you do not — finished in white, black or a colour to match the building.

Collapsible or fixed
Collapsible grilles fold back to the side of the opening, so a shop can be shut behind a grille at night and open normally in the morning, and a domestic window keeps its light and its fire escape route. Fixed bars and grilles are the stronger option where an opening never needs to be used — cellar lights, plant rooms, rear windows, storage.
Where they are usually wanted
- Ground floor and basement windows, particularly to the rear or a side alley
- Shop and commercial premises, behind the glazing line
- Flat roof access windows and anything reachable from an outbuilding
- Store rooms, plant rooms, stock rooms and cash offices
- Garage and workshop windows and side doors
- Empty or holiday properties
Fire escape
Anything fitted to a window that forms an escape route has to open from the inside without a key. That is a hard constraint on the design, not an optional extra, and it is dealt with at the survey rather than discovered afterwards.
Also fitted
- Frame and lock guards, and London bars, to reinforce doors rather than block windows
- Window bars made to a non-standard opening
- Hasps and staples, and closing shackle padlocks, for gates and outbuildings
Common questions
Will a grille stop me getting out in a fire?
Not if it is specified properly. Any grille on an escape window is fitted so it releases from the inside without a key. That requirement is settled at the survey, before anything is made.
Do they have to look institutional?
No. Finishes come in white, black or a colour to match the frames, and a collapsible grille sits folded to the side of the reveal when it is open. On period buildings the profile and colour can be chosen to disappear rather than announce itself.
Can you make one for an odd-shaped opening?
Yes — bespoke fabrication is done in-house, so an arched, tapered or non-standard opening is not a problem. See bespoke security and steel fabrication.
Will my insurer reduce the premium?
Some will, some will not, and some require bars on specific openings before they will cover the property at all. Worth asking them directly before you commit — and worth getting the requirement in writing.
