Types of UPVC Door Handles
If your door handle made of uPVC needs replacing it's essential to choose the correct replacement for your home. A locksmith can provide and install high-security uPVC door handles with extra security features.
The most important measurements you should take are the measurement A (also called PZ) and the length of the backplate. Check these measurements to ensure that your new uPVC handles will fit.
Lever/Lever
A lever is a rod that pivots around an object. When you apply force to the end, the fulcrum will move in the direction of the force is applied. This motion increases the force applied, allowing you to lift or move something that would require more force if you tried to apply directly to the load.
The distance between the fulcrum of the lever and the point where you apply force determines the maximum movement. This is referred to as the mechanical advantage. The more the lever is extended more, the greater the mechanical advantage. You can calculate mechanical advantage by dividing distance from fulcrum point to the place where you apply force by the distance between the fulcrum point and end of the lever.
Levers can have different effects depending on the way forces are applied. A class 2 lever, for example is prone to turning in the opposite direction when the force of the effort is applied. If you push on the door handle and force it to open, the forces will cause similar rotational effects to this.
However, levers don't create energy. Levers multiply the force by changing small amounts of effort applied over a long distance into greater amounts of force applied over smaller distances. Levers are used to lift heavy objects and transport large amounts of cargo. The lever principle is also employed in everyday tools such as crowbars. Hammer claws fishing rods, hammer claws and even your own legs, when you are standing on your car's hand brake.

Lever/Snib

Snib buttons can cause problems in some cases, especially when you have old locks and warped doors. If the snib switch is accidentally pressed or by someone who isn't familiar with it, your door may slam and lock you out.
