Everest GrabLock windows

Introducing new GrabLock

We're pleased to announce the launch of GrabLock, our most innovative and secure uPVC window lock yet, developed exclusively with leading lock manufacturer, Yale, the home security specialists. Made of highly durable and non-corrosive aluminium, the window lock not only offers you the best in home security, it's also been designed to be stylish and discreet.

Keeping you safe & secure

GrabLock has three times the locking surface area of a standard, multi-point or shoot-bolt window lock, making it our most secure lock ever. Formed of a sleek rotating cylinder that quite literally 'grabs' a specially designed 60mm long 'keep' on the window frame, makes it one of the most secure double glazing window locks because of the highly effective bond.

Rigorously tested

As with everything at Everest, we don't just like to say it's the best, we wanted to prove it too, and show you GrabLock's strength. So, with the help of Wintech, an independent testing laboratory and certification body, we put our new latches through some pretty extensive and rigorous tests for strength and security.

It's safe to say, GrabLock passed the test

GrabLock surpassed all of our expectations, taking everything that was thrown, dropped, rammed and hung off it in its stride.

Strength test

GrabLock is super strong

The window security lock passed the strength test, by hanging the weight of a 600kg grand piano from it.

Weather and corrosion test

GrabLock is highly durable

Passing weather and corrosion tests using salt spray and freezing temperatures.

Security test

GrabLock stops intruders

Exceeding the British security standard test PAS 24 where Dave tried to break into the window for more than 15 minutes.

Endurance test

Grablock passed the endurance test

Billy the robot opened and closed the window and lock a whopping 30,000 times, the equivalent of 41 years of daily use.

Force test

GrabLock is virtually impenetrable

Withstanding 4500 newtons of force making it virtually impossible to pass through or enter.

Secured by Design

GrabLock qualifies for 'Secured by Design'

A seal of approval which is a police initiative to design out crime through better product design.

Watch our TV advert

For our TV advert, we suspended a 600kg (0.6 tonne) grand piano from a GrabLock and stood presenter Craig Doyle under it, to show its strength. The new GrabLock surpassed all our expectations, without opening, breaking or cracking. We're pleased to show you it's one of the strongest window safety catches available.
