Types of UPVC Door Handles If your upvc door handle is in need of replacement, it's important to choose the correct replacement for your home. Locksmiths can provide and install high-security uPVC handles with added security features. The most important measurements to consider are the measurement A (also called PZ) along with the length of the backplate. Take these measurements to make sure that your new uPVC handle will fit. Lever/Lever A lever is a solid bar pivoted around a point (known as a the fulcrum). When you apply force to the end of the lever it tends to rotate the fulcrum to the direction of the force. This rotates the fulcrum, increasing the force applied and allows you to lift or move something that would require a greater amount of force if you were to apply directly to the load. The distance between the fulcrum to the point where you apply the force determines the distance the lever can move. This is known as the mechanical advantage. The greater the length of the lever, the larger the mechanical advantage. You can calculate the advantage of mechanical by dividing distance from the fulcrum point to the point at which you are applying force by the distance between fulcrum point and the end of lever. Levers can have a variety of effects based on the method by which the force is applied. For instance a lever of class 2 tends to rotate in the opposite direction when the force of effort is applied (like a totter-totter). The forces produced when you push on the handle of a front door will create rotational effects similar to those. However, levers don't create energy. Levers increase the force by converting small amounts of effort applied over a lengthy distance into greater amounts of force that are applied over shorter distances. This is what enables you to do more work in a shorter period of time, and that is why levers are commonly used for lifting heavy objects or moving large amounts of cargo. This is also the principle behind the levers that are found in many everyday tools such as crowbars and fishing rods, claws for hammers, and even your legs when you sit on the hand brake of your car. Lever/Pad Lever pad handles are a kind of upvc door handle that has levers on both sides that operate the multipoint lock. They are available in a variety of finishes & variations and can be installed on a variety of materials such as UPVC doors, Aluminium doors & Timber Doors. They are sold in pairs for the inner and outer door with spindles & screws included. They are also available in handed and unhandled versions to suit different types of users. They are typically used for new constructions and can be installed to replace existing doors made of upvc. The levers are lifted to open the multipoint locks and the key is turned to lock or close the door. They provide additional security compared to standard lever door handles because the locking function can only be accessed via the inside using an open key, unless the door is deadlocked. They are not as secure as a cylinder bolt but are a cost-effective alternative to add security. The only disadvantage is that they do not provide the same level protection as a cylinder lock and they don't restrict access to the home when the door is left open. We stock a large number of lever pad upvc handles that are manufactured by leading manufacturers in the market. They are made from high-quality components. They also come with a manufacturer's guarantee. They usually are designed to work with the 92mm lock or a replacement version called the Paddock Lock. They will feature an 82mm cylinder centre on the inside, and 62mm outside. They also come with two spindle followers. Some come with the backplate, and others are movable to accommodate different fixing centers. Lever/Snib Lever latches are the simplest kind of door handles. By pressing down on the lever, it is a simple mechanism that opens inside the door to keep it closed, which can be locked with a key. The levers for privacy are in the same way however, with the addition of a lock snib (like a doorknob). A snib button is very beneficial, especially for homes where it's crucial to maintain privacy or security. If your partner is arriving home late from work, you can apply the snib to ensure they can't get in until they're ready in. This kind of handle can also be put in on interior doors such as those in bedrooms, where you wish to limit access from outside. In certain situations the snib button can cause issues, especially in the case of doors and locks that are warped. If the snib switch is accidentally pressed, or by a person who isn't familiar with it, your door may shut and lock you out. Most of the time, you can gain entry by knocking on the door frame or letterbox, but this isn't the best option. If your uPVC door has a snib button it is recommended to replace the handle with a contemporary E-LOK 7-Series smart lock. These can be retrofitted over pull handle kits that double turn and come with cover plates to conceal the holes that are already present, allowing to ensure a seamless installation. The E-LOK app can be used to open doors with RFID cards or mechanical keys. Passcodes are also offered for convenience and security. The system has been tested to 200k cycles to ensure durability. The handles are made from solid metal and meet BS EN 1670 Grade 5 for corrosion resistance. Lever/Moveable Pad This popular handle design is used for front doors. It offers the benefit of preventing the door from being opened without the key from 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 kind of handle is designed to fit uPVC doors fitted with multipoint locks that operate with a split spindle operation. This type of operation requires that the internal lever handle and the external pad handle be attached to the same lock case. This could be a straightforward replacement for the current uPVC handle, however it may also require a new lock case or a brand new set to handle furniture.

They also come with fixing lugs spring cassettes and a non-stick slide bearing. They have a euro profile cut out and can be fitted to a wide range of uPVC and timber doors. The lever-movable pad is available in many finishes to suit a wide range of multipoint locks. They are designed to work with split spindle multipoint locks which have a 92mm cylinder and require a specific split spindle set that is provided by the lock manufacturer.

Lever/Moveable Snib The lever/lever handle is one of the most well-known types of upvc door handles and is available in a variety of styles.
