Types of UPVC Door Handles If your upvc door handle requires replacement, it is essential to choose the correct replacement for your home. A locksmith can offer 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 the new uPVC handle will fit. Lever/Lever A lever is a rigid bar that is pivotally positioned around a point (known as a Fulcrum). When you apply force towards the end, the fulcrum will rotate in the direction that the force is applied. This rotates the fulcrum, increasing the force applied which allows you to lift or move something that would require a greater amount of force if you attempted to apply directly to the load. The distance between the fulcrum and the point where you apply the force determines the distance the lever can be moved. This is known as the mechanical advantage. The mechanical advantage increases as the lever is extended. You can calculate the mechanical advantage by dividing the distance from the fulcrum to the point at which you are applying the force by the distance between the fulcrum and the point at which you are applying the force. the lever. Levers can produce different effects based on the method by which the force is applied. A lever of class 2, for example, has a tendency of rotating in the opposite direction when the force of the effort is applied. If you push the handle of a door the force will create similar rotational effects to this. However, levers don't create energy. They simply multiply the force you exert by making a small amount effort over a large distance into a larger amount of force applied over a smaller distance. Levers are used to lift heavy objects and move huge quantities of cargo. The principle of the lever is also employed in everyday tools such as crowbars. Hammer claws, fishing rods and your own legs, as you stand on the hand brake of your vehicle. Lever/Pad Lever pad handles, also known as upvc door handles feature levers on both sides to operate the multipoint locks. These come in many variations and finishes, and can be used with a variety of materials including UPVC, Aluminium & Timber doors. They are sold in pairs for the inner and exterior door with screws and spindles included. They are available in hand- and non-handled versions to suit different users. These are often used for new builds and can be used to replace the existing upvc doors. They are usually operated by lifting the levers to throw out all of the multipoint locks, and turning the key to close and unlock. They offer a little more security than traditional lever door handles because locking is only done from the inside using the key. They're not as secure as a cylinder lock but they are a cost-effective way to add extra security to 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. We have a wide selection of lever pad upvc handles that are made by top manufacturers in the market. They will therefore be constructed with top quality components. They also come with a manufacturer's warranty. They are typically designed to work with the 92mm lock, or a replacement version called a Paddock Lock. They will feature an 82mm cylinder centre on the inside, and 62mm on the outside. They also come with two spindle followers. Some are supplied with the backplate, and others are removable for different fixing centers. Lever/Snib Lever latches, the simplest of door handles are utilized. By pressing down on the lever, it triggers a simple latch mechanism inside the door to keep it closed, which can be locked using the use of a key. Certain lever privacy handles operate in the same way, but with an additional snib, similar to the doorknob. A snib button is very useful, especially in homes where it's essential to maintain privacy or security. You can use the snib handle to prevent your partner from entering until they are prepared. This type handle can also be used on doors inside, such as those in bedrooms, where you wish to limit access from outside. In certain situations, snib buttons can cause problems, particularly if you have older locks or doors that are bent. If the snib switch is accidentally pressed or by a person who isn't familiar with it, the door could slam and lock you out. You can usually gain entry by knocking the door frame or the letterbox. But this isn't a good idea. If your uPVC door has a snib button We recommend replacing the handle with an modern E-LOK 7-Series smart lock. These can be retrofitted over double turn pull handle kits and come with cover plates that hide the holes that are already present, allowing to ensure a seamless installation. The E-LOK uses a smart app that allows you to unlock the door with mechanical keys or RFID cards, and can be configured with passcodes for secure entry and convenience. The system has been tested to 200 000 cycles to ensure long-term durability. The handles are made of solid metal and meet BS EN 1670 Grade 5 for resistance to corrosion. Lever/Moveable Pad This is a popular handle style for front doors. It has the advantage of stopping the door from opening from the outside without a key, if the lock isn't deadlocked. This is achieved by the 'pad'-shaped external handle that locks in the gap between the handles and lock case to prevent the latch from being removed or the door opened. This kind of handle is designed to fit uPVC doors fitted with multipoint locks which operate via a split spindle operation. This kind of operation requires the internal lever handle and the external pad handle to be installed on the same lock case. This can be a simple replacement of the current uPVC handle, but it may also require a change in the lock case or a new set of handles to handle furniture. These aluminium lever/movable pad handles are suitable for uPVC doors and feature a maintenance free slide bearing as well as spring cassettes and fixing lugs supplied.

The lever-movable pad is available in various finishes to suit a wide variety of multipoint locks. They are designed to work with split spindle multipoint locks with an 92mm cylinder center and require a specific split spindle set that is provided by the lock manufacturer.
