NO-GO GLASS WINDOW LOCKS - SIMPLE,
UNIQUE AND HIGHLY EFFECTIVE
The best inventions come from personal experience and it was
through his previous jobs both as a double glazing installer and later
as a “window doctor” that David Murphy, founder of No-Go Security
Products, came up with his simple, unique but highly effective idea.
In the course of his work, David had noticed
how often he was being called out to replace
glazed units that had been removed by
intruders. It wasn’t difficult to see how easy it
was for burglars to gain access to a property
fitted with unsecured externally beaded
PVCu double glazed windows.
David saw how distressing these incidents
were for the householders concerned and gave
the problem some serious thought before he
developed the concept of the No-Go Glass
Lock.
Like most of the best ideas, the concept is
a simple enough one. One of those products
that make you wonder why no-one had
thought of it earlier, in fact.
No-Go Glass Window Locks, which are
manufactured in Oswaldtwistle, Lancashire
and are protected by patent, consist of two
parts. The lower base part is bonded to the
glass using a specially developed bonder.
Once bonded correctly it is impossible to
separate the glass and the metal base. A
second ‘shim’ is screwed to the base which
locks around the window frame. This shim
is designed to fit virtually all window frame
profiles.
With the panel locked to the frame in at
least two corners (but preferably all four) it
is not possible to remove the panel without
breaking the panel. This requires considerable
force, is likely to make noise and shatters
the inner glass pane. To remove the glass
completely the intruder needs to break the
outer pane and climb through – a big
deterrent.
It is important that the correct installation
procedures are closely followed, but Phil
Brown, the company’s technical consultant,
has made this easy with an on-line video
tutorial and an instruction manual
downloadable from the website (www.

For security professionals who have not yet
discovered the advantages of these products,
they are well worth invest Y
