| When
it comes to front and back doors,
door security is paramount –
which is why all our Patio Doors
incorporate a range of security
features. The
locking lever throws a high
shear strength metal shoot bolt
deep into the surrounding frame.
A
strong metal keep is fixed securely
into the frame head.
The
door locks into the frame jamb
via four steel mushroom-headed
bolts to prevent the door being
lifted off its tracks.
