What door knobs are made out of?
The world’s first doors were most likely simple textiles or animal hides used to hang over entrances to houses before wooden doors came into fashion in ancient Egypt and Mesopotamia. At this time, as the swinging door was invented, the door knob was also invented as a simple way to open and close them.
Over the years, the materials used to make door knobs have been varied. Traditionally they were made of wood before glass door knobs, ceramic and china grew in popularity in the 1800’s. Today, metal, and in particular brass, is used to make the majority of door knobs, partly because brass has the ability to disinfect itself so these door knobs don’t carry bacteria in the same way aluminium and steel ones do.
Door Knobs vs Door Handles (Lever furniture)
One of the main considerations for people looking for door furniture is whether to use a door knob or door handle (otherwise known as lever furniture) with plenty of advantages and disadvantages to each.
Door knobs tend to be a favourite for older, period properties as they have a classic look and also many of these doors will have surface mounted rim locks fitted which are perfectly compatible with door knobs. They can also come in an array of styles, colours and finishes such as oval and egg-shaped knobs which can help people who may have issues with dexterity.
On the other hand, door knobs generally tend to be smaller than door handles which means there is less for someone to grip onto when opening and closing the door, even if a slightly different shape is used. Furthermore, though traditionally they tend to be set further into the door than handles so that the user doesn’t hit their knuckles on the door frame, many modern doors do not allow for this meaning injury could occur when people are trying to open the door.
Door handles can be much more convenient for people when opening and closing doors – even if your hands are full, you can easily open the door using your elbow, also they are fitted with a gap protruding away from the door so you are unlikely to catch your knuckles on the door when grabbing the handle.
However, door handles may not suit period properties, both from an aesthetic point of view and also if the door has surface mounted rim locks then they may be incompatible. Furthermore, loose clothing can potentially get caught on the handle as you walk through and they may require more maintenance over time than door knobs as they contain springs to hold the handle lever in position.
Are door knobs “standard size”?
No door knobs are not standard sizes and you will need to measure your door to find the most appropriate size for you. For this you will need to know the diameter of the “bore hole”. This is the hole in the door where the door knob or door handle is fitted to each side. You will also need to know the “backset” which is the distance from the bore hole to the edge of the door as well as your door’s thickness. The cross bore is usually about 2 1/8 inches and door thickness is between 1 and 1/4 and 3 inches.
Note that whilst most door knobs will be able to work with a variety of different measurements, it is a good idea to measure beforehand so you do not waste time and effort fitting a door knob which will not fit the door.
What is the difference between a mortice, rim and centre door knob?
A mortice door knob is designed to be used with a latch or mechanism that is set within the door to lock it. This means for a mortice lock a hole will need to be cut within the door for the latch to be inserted.
However, a rim lock usually is a plate which is mounted onto the door so there is no need to cut a whole within a door. Generally, these types of locks are cheaper as they do not require cutting through the door which needs to be done with a great deal of precision for the mechanism to work.
A centre door knob sits in a completely different place to a rim or mortice lock which usually sits on the side of the door close to one of the edges, whereas a centre door knob (or door pull knob) usually sits dead centre within the door.
The type of door knob which you need to use for your doors depend on this decision as the door knobs are only compatible with one type of latch. However, unless you are replacing your doors at the same time this decision will largely have been made for you by your current doors and what latches they use to open and close the doors but generally rim locks tend to be the most common as they are cheapest and require minimal changes to the door to actually implement.
