Types of UPVC Door Handles When your upvc door handle requires replacement, it is essential to choose the correct replacement for your home. Locksmiths can supply and install high-security uPVC door handles that have additional security features. The most important measurements are measurement A (known as PZ) and the length of the backplate (measurement F). Check these measurements to ensure the new uPVC handle will fit. Lever/Lever A lever is a rigid bar that pivots around a central point (known as a Fulcrum). When you apply force to the end of the lever it will tend to rotate the fulcrum to the direction of the force. This rotation multiplies the force applied which allows 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 known as the mechanical advantage. The advantage of mechanical force increases when the lever is extended. You can calculate the advantage of mechanical by dividing distance from the fulcrum point to the point you apply force by the distance between fulcrum point and the end of the lever. Levers can produce different effects based on how forces are applied. For example, a class 2 lever has a tendency to turn in the opposite direction when the force of effort is applied (like a teeter-totter). The forces produced by pushing the handle of a front door can result in rotational effects similar to these. However, levers don't create energy. Levers multiply the force by converting small amounts of effort applied over a lengthy distance into greater amounts of force applied over smaller distances. upvc replacement door handles are used to lift heavy objects and move large quantities of cargo. The lever principle is also utilized in everyday tools like crowbars. Hammer claws fishing rods, hammer claws, and your own legs, when you stand on your car's hand brake. Lever/Pad Lever pad handles, also known 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 used on a wide range of materials that include UPVC doors, Aluminium doors & Timber Doors. They are sold as a pair for the outer and inner door, with screws and spindles included. They are also available in handed and unhandled versions to suit different users. These can be used to replace the existing upvc door. The levers are raised to open all multipoint locks and the key is turned to lock or close the door. They provide a bit more security than traditional lever door handles since locking is only done from the inside using a key. They are not as secure as a cylinder bolt, but are a cost-effective alternative to add security. The only downside is that they don't provide the same level of security as a cylinder lock and so don't prevent external access to the home if the door is left open. We have a wide selection of lever pad upvc handles manufactured by leading manufacturers in the industry. They will therefore be made with high quality components. In general, they come with a manufacturer's guarantee. They are typically designed to work with the 92mm lock, or a substitute version known as a Paddock Lock. They will have a 92mm cylinder centre on the inside and 62mm on the exterior and be equipped with two spindle followers. Some are fitted with the back plate whilst others are movable to enable different fixing centres. Lever/Snib Lever latches are by far the most simple type of door handles. The lever is pulled down to operate a simple latch inside the door, which can be locked with a key. Certain lever privacy handles work using the same principle however, with the addition of an Snib (like knobs for doors). A snib button is very useful, especially in homes where it's essential to protect privacy or ensure security. You can use the snib feature to stop your guest from entering until they are prepared. This kind handle is also used in interior doors like bedrooms, where you may need to restrict access from the outside. In some cases, snib buttons can cause issues, especially when you have older locks and doors that are warped. If the snib button is used in a mistake or by a person who isn't quite used to it, the door may close and shut you out. Usually, you can still gain entry by knocking on the door frame or letterbox, but this isn't the best option. If your uPVC door has a snib lock, we recommend replacing the handle with an modern E-LOK 7-Series smart lock. These locks can be retrofitted on double turn pull handle kits and are available with cover plates that hide existing holes to make it a seamless installation.

The system is tested to 200k cycles to ensure durability. The handles are made of solid metal and are in compliance with BS EN 1670 Grade 5 for resistance to corrosion. Lever/Moveable Pad This popular handle style is typically used for front doors. It has the advantage of preventing the door from being opened without a key from the outside if the lock has not been deadlocked. This is achieved by using the 'pad-shaped' handle that locks into the gap between the handle and lock case. This type of handle is designed for uPVC doors fitted with multipoint locks which operate via split spindle operations. This kind of operation requires the internal lever handle as well as the external pad handle to be installed within the same lock case. It could be a simple replacement of the current uPVC handle, however it may also require a new lock case or a brand new set to handle furniture. These aluminium lever/movable pads door handles are able for use on uPVC and feature an easy-to-maintain slide bearing. They also include fixing lugs, spring cassettes and an unstick slide bearing.
