Standard Face-Fix AKA Vertical Bracket


The newest version of our “Standard Face-Fix” option is our fully tested vertical bracket fixing: a sleek colour-coded solution for window security, giving a matching colour product for your home or office.

There are three standard colours available: white, brown and black. Our “Elite” colour range is detailed further down this page.


Cable colours come in black or white: white cables as standard with white restrictors and black for the brown and black options. The standard (and recommended) restrictor length is 200mm, but other lengths can be provided on request.


There are key-plugs available in white, black and green for a small additional charge should it be necessary to make the restrictor "non-lockable". Or we have a new dedicated "Non-lockable" option now available. Contact us for more details or to discuss your requirements.


The cable can be disconnected by "push-button" and can also be totally deadlocked to stop removal by key-locking the button.


Two keys are provided with each unit.

Window Handle Fixing


This version consists of a handle base plate (2mm) to secure below the handle base covered with sheathed steel cable (5mm o/d) fixed to the handle base. The cable will allow a 100mm opening of the sash and is connected to a frame block. The cable can be disconnected from the frame block by "push-button" and can be totally secured to stop removal by key-locking the button.

Any handle backplate can be provided subject to decent order sizes and will be priced as necessary.


Door Version


Consists of similar parts to the above and operates in a similar fashion but with a backplate to suit the door handle. Standard backplates include Hoppe 3070 Handle B/plate, backplate to suit Trojan 210mm and 240mm long handles and Fab and Fix handle backplates. However any handle can be accommodated if required, subject to decent order levels. The standard cable will allow 150mm opening but can be lessened if required.


"Elite" Finish
