Locking
For the purpose of added security we recommend fitting doors and windows
with 3 point locking mechanisms.the lock we fit has a geared locking action
which allows it to operate smoothly.this gearing makes it almost impossible
for would be intruders to drive a locking point out of location, and all
3 locking points are independent of each other; therefore if one point
fails the other two remain located.on sliding windows and doors a centre
lock is available for extra security. A centre lock consists of a hardened
steel pin which neatly loates within the two meeting styles of the sliders.they
are key locking and cannot be breached by would be intruders.
Options:
Crystal now offers a range of security options to upgrade your window
and door security including concealed key barrel/ lock cores as well as
the very highest security locking barrels (drilling of key barrels by
World be intruders is becoming more common place).
All Crystal doors in aluminium or PVC come with high security hinges and
high security lock barrels as standard. An upgrade is available on barrel
locks which by use of hardened steel prevents barrels from aging, drilled
out or knocked out.
On side hung windows in aluminium and PVC an option of hardened steel
cam locking points can be added to the standard multi point locking system
On sliding doors in aluminium and PVC a steel pin centre lock is availabe which renders the sliding leaves unmoveable when attacked or jemmied from any direction.
All Crystal windows persianas
come with security bolts in the final or terminal slat, with the option
of a lockable hardened steel drive in the terminal slat .
Crystal can offer a vast range of traditional rejas ( traditional spanish
style wrought iron security grills) which are galvanized dipped and often
painted for long life as standard.
An option in grills is extendable rejas which can open completely back and swing out and against house wall with fold away head and bottom guides when not required and lock with concealed drive when closed.
