Good-quality door furniture is made in satin-anodized aluminium; this is strong and hard-wearing. Various other finishes are available in various makes, including bronzed and black- or white-painted door furniture.
Door furniture is “handed” left or right; this determines its fixing position.
Mortise locks and latches, rim locks and cylinder locks (a form of rim lock), door handles and door pulls are all categorized as door furniture.
For outside and security doors, a mortise lock is best fitted. For other situations, a simple lever handle or door knob can be fitted.
Among the simplest of latches is a spring-roller catch, the pressure of which can be adjusted, to keep a door closed; this is used with a door handle or door pull.
The height of a door handle is a matter of choice but the handle will look best if it has a definite relationship to any glazing bars. A midway position is neatest. Fixing a lock and latch. This is a task requiring some precision.
1 Square a line around the door stile at the desired height. Then gauge the distance of the latch on the stile face.
2 Bore, with a bit and brace, a hole ¾ in. (or 1.6 cm) to accept the latch spindle.
3 Bore and then chisel out a slot in the lock stile to take the body or barrel of the lock. The size of the slot depends on the size and shape of the body. Square lines with a try-square and marking gauge. Use the head of the barrel as a direct template to aid accurate marking.
4 The headplate of the barrel is recessed into the stile, so you should first cut out a shallow slot for this. Drill a series of holes corresponding with, but just less than, the body width and chisel out squarely.
5 Put in the barrel and screw the end plate to the face of the stile.
6 Finally attach the spindle and door handle.
The position of the striking plate can be established by direct transfer from the latch when the door is closed. Then cut a small mortise through the holes in the plate to accept the latch.
The action of closing the door is smoother if the lead-in part of the striking plate is bent back slightly and recessed into the door frame.
