Check Out: How Upvc Door Handles Is Taking Over And What Can We Do About It
Types of UPVC Door Handles
When your upvc door handle needs replacing it's essential to choose the correct replacement for your home. Locksmiths can provide and fit high-security uPVC handles with added security features.
The most important measurements are measurement A (known as PZ) and the length of the backplate (measurement F). Take these measurements to make sure your new uPVC handle will fit.
Lever/Lever
A lever is a rigid bar that pivots around a central point (known as a the fulcrum). When you apply force towards the end, the fulcrum will turn in the direction the force is applied. This rotates the fulcrum, increasing the applied force and allows you to lift or move something that would require a greater amount of force if you were to apply it directly to the load.
The distance between the fulcrum of the lever and the point where you apply force determines the maximum amount of movement. This is known as the mechanical advantage. The greater the length of the lever the greater the mechanical advantage. You can calculate the advantage by dividing the distance from the fulcrum until the point at which you are applying the force by the distance between the fulcrum and the end of the lever.
Levers can also have different effects based on the way in which forces are applied. For instance, a class 2 lever is inclined to turn in the opposite direction when the effort force is applied (like a totter-totter). If you push the door handle, the forces will produce similar rotational effects to this.
However, levers don't create energy. They just multiply the force you exert by changing a small amount of effort over a large distance into a larger amount of force applied over a shorter distance. Levers are used to lift heavy objects and transport huge quantities of cargo. This is also the reason behind the levers that are found in many everyday tools like crowbars and fishing rods, claws for hammers and even your legs when you sit on the hand brakes of your car.
Lever/Pad
Lever pad handles, also referred to as upvc door handles, have levers on each side to operate the multipoint locks. They are available in a variety of finishes & variations and can be installed on a wide range of materials, including UPVC doors, Aluminium doors & Timber Doors.

They provide a bit more security than the standard lever handles for doors because locking is only done through the inside with a key.
They're not as secure as a cylinder lock, but they're a cost-effective way to increase the security of your home. The only drawback is that they don't offer the same level of protection like a cylinder bolt and therefore won't prevent access from outside if the door has been left open.

Lever/Moveable Pad
