Types of UPVC Door Handles It's important to choose the correct replacement Upvc handle for your home when your handles made of upvc require replacement. A locksmith can offer and install high-security uPVC door handles that have additional 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 your new uPVC handles will fit. Lever/Lever A lever is a rigid bar that is pivotally positioned around a point (known as a Fulcrum). When you apply a force to the end of the lever, it will tend to rotate the fulcrum in the direction of the applied force. This motion increases the force and allows you to lift or move objects that would normally require more force to lift. The distance between the fulcrum to the point where you apply the force determines the distance the lever can be moved. This is referred to as the mechanical advantage. The advantage in mechanical terms increases as the lever gets extended. You can calculate the mechanical advantage by dividing distance from the fulcrum point to the point you are applying force by distance between fulcrum point and the end of lever. Levers can produce different effects based on the method by which forces are applied. A lever in class 2 for instance has a tendency of turning in the opposite direction when the force of the effort is applied. The forces generated by pushing the handle of a front door can produce rotational effects that are similar to those. However, levers don't create energy. They just multiply the force you exert by changing a small amount of effort over a large distance into a greater amount of force applied over a smaller distance. Levers are used to lift heavy objects and transport large quantities of cargo. The lever principle is utilized in everyday tools like 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 form of door handle made from UPVC with levers on both sides that operate the multipoint lock. These are available in a variety of finishes & designs and can be used on a wide range of materials, including UPVC doors, Aluminium doors & Timber Doors. They are sold in pairs for both the doors, both exterior and interior with screws and spindles included. They are also available in hand and unhandled versions for different types of users. These can be used to replace existing upvc door. The levers are lifted to open all the multipoint locks, and the key is turned to lock or close the door. They are more secure compared to lever handles for doors since the locking mechanism is only accessible from the inside with an open key, unless the door is locked. They are not as secure as a cylinder bolt, but are a reasonable option to provide extra home security. The only disadvantage is that they do not provide the same level protection like a cylinder lock and so don't prevent external access to the home when the door is left open. We stock a large number of lever pad upvc handles that are made by top manufacturers in the industry. They are made from high-quality components. In general, they are supplied with a manufacturer's guarantee. Typically, these will be designed to work with a 92mm lock, or the replacement version of this called a Paddock lock. They will feature a cylinder with 82mm diameter on the inside, and 62mm outside. They are also fitted with two spindle followers. Some come with the backplate in place, while others are movable to accommodate different fixing centers. Lever/Snib Lever latches are by far the most simple type of door handles. The lever is pushed downwards to open a latch inside the door that can be locked with a key. Some lever privacy handles operate based on this same principle but with the addition of an lock snib (like the doorknob). A snib-button can be very beneficial, especially for homes where it's crucial to protect privacy or ensure security. You can use the snib feature to block your partner from entering until they are prepared. This type handle is also used for interior doors, such as bedrooms, where you may want to restrict access from the outside. Snib buttons can cause issues in some cases, especially when you have locks that are old and warped doors. If the snib is applied in a mistake, or by a person who isn't quite used to it, the door could close and lock you out. In most cases, you can get in by knocking on the door frame or the letterbox, but this isn't the best option. If your uPVC has an snib, we suggest replacing it with an electronic lock from the E-LOK 7 Series. These smart locks can be retrofitted onto double turn pull handle kits.

The handles themselves are made with a solid metal construction and are BS EN 1670:2007 Grade 5 for resistance to corrosion. Lever/Moveable Pad This is a popular handle design for front doors. It comes with the advantage of keeping the door from opening from the outside without a key if the lock is not deadlocked. This is accomplished by the 'pad'-shaped external handle that locks in the gap between the handles and lock case to prevent the latch from being pulled back or the door opened. This handle is designed to work with uPVC multipoint locks that use a split spindle mechanism. This kind of operation requires that the lever handle and external pad handle both be fitted to the same lock case. It could be a simple replacement for the current uPVC handle, however it may also require a new lock case or a new set to handle furniture.
