Types of UPVC Door Handles If your door handle made of uPVC requires replacement, it is essential to choose the correct replacement for your home. A locksmith can supply and fit high-security uPVC handles with extra security features. The most important measurements are measurement A (known as PZ) and the length of the backplate (measurement F). Make door handles repairmywindowsanddoors to check these measurements to ensure the new uPVC handle will fit. Lever/Lever A lever is a rigid bar that is pivotally positioned around a point (known as a the fulcrum). When you apply a force at the end of the lever, it will tend to rotate the fulcrum in the direction of the applied force. This motion increases the applied force which allows you to lift or move something that would require more force if you tried to apply it directly to the load. The distance between the fulcrum to the point where you apply the force determines how far the lever can move. This is referred to as the mechanical advantage. The greater the length of the lever the greater the mechanical advantage. You can calculate the advantage of mechanical by dividing the distance from fulcrum point to the place where you are applying force by the distance between the fulcrum point and end of the lever. Levers can have a variety of effects depending on the way forces are applied. For instance a lever of class 2 tends to rotate in the opposite direction as the force of effort is applied (like a T-totter). If you push on the handle of a door and force it to open, the forces will cause similar rotational effects to this. However, levers don't create energy. They simply multiply the force you exert by converting a small amount of effort applied over a long distance into a greater amount of force applied over a shorter distance. Levers are used to lift heavy objects and move massive quantities of cargo. The lever principle is used in everyday tools like crowbars. Hammer claws, fishing rods and your own legs when you stand on the hand brake of your car. Lever/Pad Lever pad handles are a type of upvc door handle that has levers on both sides to operate the multipoint lock. These are available in various finishes and variations and can be used on a wide range of materials that include UPVC doors, Aluminium doors & Timber Doors. They are sold in pairs for the inner and exterior door, with spindles and screws included. They are also available in both handed and unhanded versions for different users. They are commonly used in new builds and can be fitted to replace existing doors made of upvc. The levers are lowered to open all the multipoint locks and the key is turned to close or unlock the door. They provide a bit more security than traditional lever door handles because locking can only be done through the inside with the key. They are not as safe as a cylinder lock however they are an affordable way to add extra security to your home. The only drawback is that they don't have the same level of security as a cylinder bolt and therefore don't stop external access in the event that the door has been left open. The majority of the lever pad upvc door handles we offer are manufactured by industry's leading manufacturers and therefore are constructed using high quality components. They are also generally supplied with a manufacturer's warranty. Typically, they are designed to be compatible with a 92mm lock or the replacement version of this called a Paddock lock. They will have a 92mm centre cylinder on the inside and 62mm on the outside. They will also be fitted with 2 spindle followers. Some are supplied with the backplate inserted, while others are movable to accommodate different fixing centers. Lever/Snib Lever latches, the simplest of all door handles, are used. The lever is pushed down to operate a simple latch inside the door that can be locked using a key. Certain lever privacy handles operate on the same principle but with a second snib, similar to the doorknob. A snib can be extremely useful tool, particularly in homes where privacy and security are important. If your partner arrives at home late from work, you can use the snib button to ensure that they aren't allowed in until they're ready to move in. This type handle is also used in interior doors, such as bedrooms, where you might need to restrict access from outside. Snib buttons can cause issues in certain circumstances, especially when you have old locks and doors that are warped. If the snib button is accidentally pressed or by someone who is not familiar with it, the door could slam and lock you out. You can usually gain entry by knocking on the door frame or letterbox. But, this is not ideal. If your uPVC door is equipped with a snib-button it is recommended to replace the handle with a modern E-LOK 7-Series smart lock. These smart locks can be retrofitted to double-turn pull handle kits. They are available with coverplates that hide existing holes to ensure an easy installation. The E-LOK uses a smart app to enable you to unlock the door with mechanical keys or RFID cards, and can be set up with passcodes to ensure security and convenience. The system has been tested for 200,000 cycles to ensure long-lasting durability. The handles themselves are made with a solid metal construction and are BS EN 1670:2007 Grade 5 for corrosion resistance. Lever/Moveable Pad This is a very popular handle style for front doors that has the benefit of stopping the door from opening by the outside without a key, if the lock isn't deadlocked. This is achieved by using a 'pad-shaped' external handle that locks into the gap between the handle and the lock case. This kind of handle is designed to fit uPVC doors fitted with multipoint locks which operate via split spindle technology. This type of operation requires the internal lever handle and the external pad handle to be fitted to the same lock case. This can be a simple replacement for the current uPVC handle, however it may also require a lock case change or a new set to handle furniture. These levers/movable pad door handles are ideal for uPVC doors and come with a maintenance free slide bearing as well as fixing lugs and spring cassettes included. These handles have an euro-profile cut out and can be fitted to many uPVC or doors made of timber. Lever-movable pads are available in a variety of finishes and suit many different multipoint locks.
