Door handle is an ambiguous term, and includes door latches, bars, and knobs. Depending on the geographical location and its place in time, they vary in design, form and materials. The only constant is its function: an attachment used to open or close a door. The earliest doors extant are approximately 5000 years old. Door handles, as devices to manipulate a gateway, became a necessity shortly after the invention of the pivoting mechanism. To most, pivots are simply known as hinges, however, there are nearly as many hinge designs and configurations as there are handles. The simplest handle is a pull - or push - projection on the side opposite the hinge. The placement of the handle is generally where it will provide an optimal mechanical advantage; most doors operating as second class levers. Doors with centre pulls or rings, or a pivot point in a location other than one edge of the door, use first or third class lever principles.
Styles shapes, materials, and function of door handles have evolved over the years. The types of door handles sold today are high-tech, made to withstand the test of time. Handles are now made with better materials and workmanship so once installed, unless you wanted a different look, the handle would last the life of the home. Some people still prefer the initial type of door handle but a growing number of home and business owners are now turning to unique handles coupled with decorative hardware. With this, the door and all its components actually become a key part of the overall look. Alone with the handle opening the door, security is another key element when buying. Today more than any other time in history, people are taking more intense measures to protect property and families. Because of this, manufacturers have designed a variety of different features for door handles that can provide a much better barrier of protection
Before proceeding with the door handle replacement project, you should collect your tools at one place and open the door slightly. Check the interior sides of the handle to find the screws. If you do not find the screws, then the door handle head should be popped-off using a flathead screwdriver. The screwdriver head should be inserted into the side slot and turned slightly. The cover on the handle will come-off exposing the screw. The screw can be turned and removed. This should be done for both sides of the handle - inside as well as outside. Then the screws on the strike plate are removed from the side of the door and then the latch is removed. In case of screen doors and storm doors, you can skip this step. The next step in door handle replacement is to take a measurement of the distance between the side of the door and the holes. This distance is called 'back set' and it can help you to make sure that the new handles will work properly with the door.
