Parts of a Door Handle


    Most people turn [url=http://www.pullhandlefactory.com/door-handle/]door handles [/url]every day and never even give a second thought to the parts of a door handle until they need or choose to replace part or all of the handle. If you're going to DIY your door hardware, it can be useful to know more about door handle components first. The parts of a door handle include knobs/levers, latch mechanisms, strike plates, boxes and cylinder locks.


    The most obviously noticeable part of the door handle is the  knob  or  lever  that actually allows the door to open. Knobs are generally round, although they may come in other shapes, and they open the door by turning, whereas levers (also called lever handles) open the door by pushing down. While it's pretty hard to  install a door handle  in the wrong direction, it's important to pay attention to the direction of a lever when installing one.


    While not the most important of door knob parts, a  rosette  is the plate behind the door handle or lever. While the rosettes in most homes are simple metal pieces, they can be elegantly detailed, and some door handles, particularly those with vintage designs, don't have a rosette at all.


    The Latch Mechanism


    Perhaps the most important of all door handle parts is the latch mechanism. This is the spring-loaded piece that protrudes past the door, keeping the door closed. While most latch mechanisms use a retracting  tubular latch  mechanism that goes in when the handle is turned, some doors, like closets, use a  ball latch. A ball latch doesn't retract when the handle is turned but instead is simply pushed open or closed in order to catch it on the specially indented strike plate.


    The latch itself is generally fitted to the door with a mortise plate, which provides additional security and makes installation more easy so the latch is properly situated in the door in order to catch on the  door frame  when the door is closed. Additionally, the mortise plate makes the latch mechanism look much more attractive than simply having a floating latch stick out the side of the door.


    When the door is pushed closed, the  strike plate  is the metal piece that the latch is pushed into on the door jam. The box is the hole where the latch fits in, which may or may not be fitted with a strike plate.


    Ball latches require a special, shallow strike plate, but most retracting tubular latches don't require a strike plate because they will still retract and go into the box when pushed against a door frame. That being said, strike plates make the door function more smoothly, look more attractive and protect the door frame from damage caused by repeatedly being pressed on by the latch.
