Types of UPVC Door Handles If your upvc door handle is in need of replacement, it's important to choose the correct replacement for your home. A locksmith can provide 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 ensure your new uPVC handle will fit. Lever/Lever A lever is a rigid bar pivoted around a point (known as a the fulcrum). When you apply force to the end of the bar, the fulcrum is likely to move in the direction of the force is applied. This rotates the fulcrum, increasing the applied force and allows you to lift or move something that would require more force if you attempted to apply directly to the load. The distance between the fulcrum and the place where you apply the force determines how far the lever can be moved. This is referred to as the mechanical advantage. The advantage of mechanical force increases when the lever is extended. upvc replacement door handles can calculate mechanical advantage by dividing distance from fulcrum point to the place where you apply force by the distance between the fulcrum's point and the end of the lever. Levers can produce different effects depending on the way the force is applied. A lever in class 2, for example is prone to turning in the opposite direction when an force applied to it. If you push on the door's handle, the forces will produce the same rotational effects as this. However, levers don't create energy. Levers multiply the force by changing small amounts of effort applied over a long distance into larger amounts of force applied over smaller distances. Levers are used to lift heavy objects and transport massive amounts of cargo. This is also the basis behind levers found in many everyday tools like crowbars, fishing rods, claws for hammers and even your legs when you sit on the hand brake of your car. Lever/Pad Lever pad handles are a type of door handle made of upvc that has levers on both sides that operate the multipoint lock. Lever pad handles are available in various finishes and designs and can be used on a variety of materials such as UPVC doors, Aluminium doors & Timber Doors. They are sold as a pair for the outer and inner door, with screws and spindles included. They are available in unhanded and handed versions to suit different users. They are typically used for new constructions and can be used to replace the doors made of upvc. They are usually operated by lifting up the levers, which throw out all of the multipoint locks before turning the key to close / unlock. They provide a bit more security than standard lever door handles since locking can only be done from the inside using keys. They're not as secure as a cylinder bolt, but are a reasonable alternative for a home with more security. The only drawback is that they don't provide the same level of security as a cylinder lock, and therefore don't block access to the home when the door is left open. The majority of the lever pad door handles made of upvc that we have in stock are manufactured by the leading manufacturers in the industry, and will be manufactured with good quality components. In general, they are supplied with a manufacturer's warranty. They usually are designed to work with the 92mm lock or a replacement model called the Paddock Lock. They will feature an 82mm cylinder centre on the inside, and 62mm outside. They also come with two spindle followers. Some come with a backplate inserted, while others are removable for different fixing centers. Lever/Snib Lever latches are the simplest kind of door handles. The lever is pulled down to activate a simple latch inside the door. It can be locked with a key. Some lever privacy handles work on the same principle but with an additional snib, similar to a doorknob. A snib button is very useful, especially for homes where it's important to ensure privacy or security. You can use the snib button to stop your partner from entering until they are ready. This kind handle can also be put in on interior doors such as those in bedrooms, where you wish to restrict outside access. Snib buttons may cause problems in certain situations, particularly when you have locks that are old and doors that are warped. If the snib button is used in error or by someone who isn't accustomed to it, the door could close and lock you out. In most cases, you can get in by knocking on the door's frame or the letterbox, but this isn't ideal. If your uPVC has an snib, we suggest replacing it with a smart lock from the E-LOK 7 Series. These smart locks can be retrofitted to double-turn pull handle kits. They are available with coverplates that conceal existing holes to ensure an effortless installation. The E-LOK uses a smart app that allows you to unlock the door using mechanical keys or RFID cards, and is able to be set up with passcodes to ensure security and convenience. The system is tested to 200,000 cycles to ensure long-term durability. The handles are constructed of solid metal and comply with BS EN 1670 Grade 5 for resistance to corrosion. Lever/Moveable Pad This popular style of handle is typically used for front doors. It offers the benefit of preventing the door from being opened without a key from the outside when the lock hasn't been deadlocked. This is accomplished by using a 'pad-shaped' external handle that locks into the gap between the handle and lock case. This handle is designed to be used with uPVC multipoint locks that use a split spindle mechanism. This type of operation requires that the internal lever handle and the external pad handle be attached to the same lock case. This can be a simple replacement of the current uPVC handle, but it could also require a lock case change or a new set of handles to handle furniture.
