Types of UPVC Door Handles It's important to choose the correct replacement upvc handle for your home when your upvc handles need replacing. Locksmiths can supply and install high-security uPVC door handles with extra security features. The most important measurements are measurement A (known as PZ) and the length of the backplate (measurement F). Make sure to check these measurements to ensure your new uPVC handle will fit. Lever/Lever A lever is a rigid rod that pivots around a point. When you apply force to the end, the fulcrum is likely to move in the direction of the force is applied. This rotation multiplies your force and lets you lift or move things that would otherwise require more force to lift. The distance between the fulcrum of the lever and the point at which you apply force determines the most effective movement. This is referred to as the mechanical advantage. The more the lever extends, the larger the advantage in terms of mechanical. You can determine the mechanical advantage by dividing the distance from the fulcrum until the point at which you're applying the force by the distance between the fulcrum and the end of the lever. Levers can also have a variety of effects based on the way in which forces are applied. A lever in class 2 for instance, has a tendency of rotating in the opposite direction when the effort force is applied. If you press on the door handle the force will create rotational effects similar to this. However, levers don't create energy. Levers multiply the force by making small amounts of effort applied over a longer distance into greater amounts of force that are applied over shorter distances. Levers are used to lift heavy objects and move massive quantities of cargo. This is also the principle behind the levers you find in a variety of everyday tools such as crowbars, fishing rods, hammer claws and even your own legs when you stand on the hand brake of your car. Lever/Pad Lever pad handles, also known as upvc door handles, feature levers on both sides to operate the multipoint locks. Lever pad handles are available in various finishes and variations and can be installed on a variety of materials, including UPVC doors, Aluminium doors & Timber Doors. They are sold in pairs for the inner and outer door, with screws and spindles included. They are available in both hand- and non-handled versions to meet the needs of different users. They can be used to replace existing doors made of upvc. The levers are raised to open all the multipoint locks, and the key is turned to close or unlock the door. They offer some extra security compared to traditional lever door handles as the locking operation is only accessible from the inside with an open key, unless the door is locked. They are not as secure as a cylinder bolt however they are a cost-effective option to provide extra home security. The only downside is that they don't offer the same level of security like a cylinder bolt and consequently don't block access to outside in the event that the door has been left open. The majority of the lever pad door handles made of upvc that we stock are made by the industry's leading manufacturers and therefore are made from high quality components. They also come with a manufacturer's warranty. These are usually designed to work with the 92mm lock or a replacement model called the Paddock Lock. They will have a 92mm centre cylinder on the inside and 62mm on the exterior and come with two spindle followers. Some come with the backplate inserted, while others are movable to accommodate different fixing centers. Lever/Snib Lever latches are by far the most simple kind of door handles. The lever is pulled down to activate a simple latch inside the door. It can be locked using a key. Some lever privacy handles work similar to the doorknob, but with a second snib, similar to a doorknob. A snib can be a very useful tool, especially in homes where security and privacy are essential. You can use the snib button to prevent your guest from entering until they are ready. This type handle is also used in interior doors like bedrooms, where you might require a lock to prevent access from the outside. In upvc replacement door handles there are instances where snib buttons could cause problems, particularly in the case of older locks or doors that are bent. If the snib button was accidentally pressed by someone who isn't familiar with it, your door may be slammed and you locked out. In most cases, you can get in by knocking on the door's frame or letterbox, however this isn't a good idea. If your uPVC has an snib, we suggest replacing it with an electronic lock from the E-LOK 7 Series. These locks can be retrofitted on pull handle kits with double turns and come with cover plates to conceal existing holes, to ensure a seamless installation. The E-LOK app can be used to open doors using RFID cards or a mechanical keys. Passcodes are also available to ensure security and convenience. The system has been tested to 200 000 cycles to ensure long-term durability. The handles are constructed of solid metal and meet BS EN 1670 Grade 5 for resistance to corrosion. Lever/Moveable Pad This is a popular handle design for front doors. It has the advantage of stopping the door from opening by the outside without a key if the lock is not deadlocked. This is accomplished by the 'pad'-shaped external handle which locks in the gap between the handles and the lock case to prevent the latch from being pulled back or the door opened. This type of handle is designed for uPVC doors with multipoint locks that operate using a split spindle operation. This kind of operation requires the lever handle and the external pad handle to be fitted to the same lock case. This could be a straightforward replacement for the current uPVC handle, however it may also require a change in the lock case or a new set to handle furniture. These aluminum lever/movable pads door handles are able for use on uPVC and come with an unmaintained slide bearing. They also include fixing lugs, spring cassettes and a non-stick slide bearing. They feature a euro-style cut out and are installed to a variety of uPVC and timber doors. Lever moveable pads are available in a variety of finishes and can be used with a variety of multipoint locks. They are designed to work with split spindle multipoint locks which have a 92mm cylinder and require a special split spindle set, as provided by the lock manufacturer.

It is made up of two inline handles that can be moved and locked by a thumbturn cylinder, or the use of a key.
