The backset is the distance from the vertical edge of the door to the centre of the hole for the spindle or the lock. It is important to know this measurement when you are lining up an escutcheon or key cover under a pair of knobs or a bathroom lock under a door knob. Sufficient backset is also critical to ensure you do not trap your fingers between the door knob and the door frame when you open and close the door.

Door Handles/Door Knobs Unsprung and Sprung
Sprung door handles or door knobs have a spring built into the backplate which allows them to spring back after turning or pushing down. These tend to be more modern examples. Unsprung door handles and door knobs do not have any springing built in and rely on the spring in the latch mechanism to do all the work. The spring in the latch must be heavy duty if door knobs or handles are unsprung. Most of our range is un-sprung as all period door knobs would have been. If you have door knobs or handles which don’t spring back then the chances are you have a latch with a weak spring which is not up to the job.

All our brass door furniture is just as our forebears produced it, without lacquer. Unlacquered brass will tarnish naturally and assume a natural patina. To keep it shiny it requires polishing regularly with a brass polish.To suit our modern lifestyle most modern brass is coated with a protective layer of clear lacquer after polishing. This is then maintenance free shiny brass. Beware, the catch is that the lacquer will breakdown over time with the effects of weather and handling. If you live by the sea it will perish faster. Once this goes you are left with an item with unsightly black marks which you cannot clean. This is often a sign of cheap brassware. Click on our article Unlacquered or Lacquered Brass?
