Types of UPVC Door Handles It is essential to select the appropriate replacement handle made of upvc for your home if your handles made of upvc require replacement. Locksmiths can provide and install high-security uPVC handles with added 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 make sure that your new uPVC handles will fit. Lever/Lever A lever is a solid bar that is pivotally positioned around a point (known as a Fulcrum). When you apply force to the end of the bar, the fulcrum will tend to rotate in the direction that the force is applied. This motion increases the force and lets you lift or move things that normally 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 known as the mechanical advantage. The advantage in mechanical terms 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 end of the lever. Levers can also have a variety of effects based on the way in which forces are applied. For example the class 2 lever has a tendency to turn in the opposite direction as the force of effort is applied (like a teeter-totter). The forces generated by pushing on the handle of a front door can result in rotational effects similar to those. However, levers don't create energy. They simply multiply the force you apply by making a small amount effort applied over a long distance into a larger amount of force applied over a smaller distance. This is what allows you to complete more work in less time, which is why levers are commonly used for lifting heavy objects or moving large quantities of cargo. The lever principle is employed in everyday tools such as crowbars. Hammer claws, fishing rods and your own legs, when you stand on the hand brake of your vehicle. Lever/Pad Lever pad handles are a kind of upvc door handle with levers on both sides that operate the multipoint lock. They come in a variety of designs and finishes and are suitable for a range of materials including UPVC, Aluminium & Timber doors. They are sold in pairs for the inner and exterior door, with spindles and screws included. They are also available in hand and unhanded versions for different users. They are typically used for new constructions and are used to replace the existing doors made of upvc. The levers are lowered to open the multipoint locks, and the key is turned to lock or close the door. They offer a little more security than standard lever door handles because locking can only be performed from the inside using the key. They're not as secure as a cylinder bolt but are a cost-effective alternative to add security. The only downside is that they do not offer the same level of security like a cylinder bolt and therefore won't prevent access from outside in the event that the door has been left open. The majority of lever pad door handles made of upvc that we stock are made by the industry's leading manufacturers and therefore are constructed using high quality components. In general, they are supplied with a manufacturer's warranty. Typically, they are designed to work with a 92mm lock or the replacement version known as a Paddock lock. repairmywindowsanddoors will feature a 92mm cylinder center on the inside and 62mm on the outside. They will also be fitted with 2 spindle followers. Some are supplied with the backplate in place, while others are removable for different fixing centers. Lever/Snib Lever latches are by far the most simple kind of door handles. The lever is pulled down to open a latch inside the door, which can be locked with a key. Certain lever privacy handles work using the same principle, but with the addition of a lock snib (like the doorknob). A snib button can be very beneficial, especially for homes where it's important to maintain privacy or security. If your partner is arriving at home late from work, you can utilize the snib button to ensure that they won't be able to enter until they're ready to move in. This kind handle is also used for interior doors such as bedrooms, where you may want to restrict access from the outside. In some cases, snib buttons can cause issues, especially if you have doors and locks that are warped. If the snib button is accidentally pressed by someone who isn't familiar with it, the door may slam and lock you out. It is possible to gain entry by knocking on the door frame or the letterbox. However this isn't the best option. If your uPVC door is equipped with a snib-button, we recommend replacing the handle with a modern E-LOK 7-Series smart lock. These can be retrofitted over pull handle kits that double turn and are available with cover plates to hide the holes that are already present, allowing for a seamless install. The E-LOK application can be used to open doors with RFID cards or mechanical key. Passcodes are also offered for security and convenience. The system has been tested to 200k cycles to ensure 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 popular style of handle is typically used for front doors. It offers the benefit of preventing the door being opened without the key from outside if the lock has not been deadlocked. This is accomplished through the 'pad'-shaped external handle that locks into the gap between the handles and lock case to prevent the latch from being pulled back or the door from being opened. This handle is designed to be used with uPVC multipoint locks that employ split spindle mechanisms. This type of operation requires that the lever handle and the external pad handle are both fitted to the same lock case. It could be a simple replacement of the existing uPVC handle, however it may also require a change in the lock case or a new set to handle furniture. These aluminium lever/movable pad door handles are suitable for uPVC doors and feature a maintenance free slide bearing, fixing lugs and spring cassettes supplied.

They are designed to be used with split spindle multipoint locks which have a 92mm cylinder centre and require a specific split spindle set, as supplied by the lock manufacturer.
