Locks & Latches
When choosing door knobs we would always recommend that the Tubular Latches, Sash Locks or Bathroom Locks that you use in your doors have a big enough backset, (distance between the edge of the door and the spindle hole), so that the door knob is far enough away from the door frame and you don't end up scraping your knuckles when operating the knob. Normally a minimum latch length would be 3" or 76mm giving you a backset of 57mm to the centre of the spindle, however depending on the type of door you have you may prefer an even longer latch.
Sprung or Unsprung
Most of the door knobs which we supply are unsprung, when fitting a pair of unsprung mortice knobs it is important to fit architectural double sprung latches and locks. Sprung door knobs have a spring mechanism incorporated in one side of the rose to assist in returning the knob and the latch or lock to the neutral position when released. All the latches and locks available on our online store are suitable for sprung door knobs however we would still recommend the use of architectural locks and latches.
