With any of our large door range here at Prior Products, you get top spec security as standard. With our composite doors, the tried and trusted Yale lock is used, along with multi point locking. For extra peace of mind these can be fitted with spy holes, or electronic door viewers.
Our Patio door range are equipped with claw hook locking which interlock between the opener and fixed sashes, thus making it impossible to lift the sash out with a spade or other similar implement - a common fault with sliding doors.
The French doors we manufacture are also equipped with high security locks, again with multi point locking and shootbolt extensions if you so desire. With key alike locks, only one key is needed to unlock both doors.
Whatever you need, we can provide the door you require.
