All door knobs are supplied in pairs and include spindles and fixings. Please note that locks and latches must be ordered separately to suit your door requirements.
Door knobs require a deeper latch than standard handles to ensure comfortable operation and to prevent hands from being caught between the knob and the door frame when closing the door towards you. We recommend using a 102mm (4-inch) latch, provided the door can accommodate this size. A 76mm latch may be suitable for some door knobs; however, we do not advise using a 64mm latch or lock unless fitting knobs to the centre of non-rebated double doors.
For unsprung door knobs, a high-quality latch is essential to ensure smooth and reliable performance.
