What is "Door Furniture"?
It is a generic term describing any fittings that attach to a door or drawer, including handles, knobs, hinges, keyholes, locks, latches, hooks, letter boxes and door bells. If you are looking to buy doors, then click here.
How do I fit door furniture?
Hinges are usually fitted in pairs, or sometimes three's, depending upon the weight of the door, as a heavy door will require heavier duty hinges. Hinges come in many types, including steel, brass and electroplated steel - where the steel has a shiny, protective coating to prevent rusting.
Hinges can be the standard "cheap" units that just have a pin through the joint, or they can be more expensive, incorporating ball bearings into the hinge joint itself, making them easier to open.
Hinges are fitted by lying the door on its side and measuring in from the edge about a quarter of the height of the door to get the hinge position. Then, by placing the hinge on the side of the door with the hinge in a 90° position, you can draw round it to mark the area that will need to be cut out. This area is cut out with a chisel, or using a router first, then a chisel just to cut the corners out.
Having fitted the hinge, the door is then lifted up into position, held against the frame and the position of the hinge is marked across onto the frame and a similar procedure is used to cut the recesses for the hinges.
The locking mechanism consists mainly of two types:
The mortice locks have the traditional long key with a shank, the shaped part of the key, at one end. They have either three or five levers on them for operating the lock. The 5 lever mortice locks offer the highest level of security.
Yale locks fitted on the inside of the door all offer a similar level of security. This unit uses a smaller type of key with complex serrations and operates a lock through the door rather than the lock iself being in the door. The disadvantage of Yale type locks is that anybody breaking into the house can open the lock from the inside, simply by clicking off the switch or opening the button. The only exception to this is a High Security Yale lock, which requires the key to unlock it from either side.
Fitting of the internal door type locks is probably not something that should be tackled by the average DIYer unless very competent - it's not an easy job and requires the cutting of a very deep hole in the door, the drilling of holes 10-11 cm deep without any deviation from the centre line to get the lock straight, and then chiselling out so that the hole is square to fit the lock mechanism.
Knobs and Handles
There are many types of knobs and handles, although the most common types are a single knob that just fits over the operating mechanism for the door latch, or a combined version that fits over the operating mechanism and provides a hole for the key to slot through.
All of these units are relatively easy to fit, requiring, 3 ,4 or 6 screws. Care needs to be taken when fitting the screws as doors can be made of fairly hard wood. The screws tend to be made from brass or electroplated brass. Being quite soft, it's easy to break them off whilst fitting them in - a tip is to drill a small prehole first.
Letterboxes often come with a separate template to mark the area to be cut out and thus aid installation. The template needs to be positioned carefully on the door so that it will not interfere with any of the joints in the wood. The hole is cut by using a drill and a jigsaw, the drill drilling a hole in each of the four corners and a jigsaw to join them up.
Hooks are usually fitted at the top of the door, but sometimes half way down, particularly in children's rooms.
Bells are normally fitted to door frame. Before fitting the bell, one usually needs to drill a hole right the way through from the outside of the frame to the inside, in order to push the bell wire itself through. The bell push is normally fitted with just two very small screws to the outside of the frame.
