Types of UPVC Door Handles If your door handle made of uPVC needs replacing it's essential to find the best replacement for your home. Locksmiths can provide and install high-security uPVC handles with added security features. The most important measurements to consider are the measurement A (also known as PZ) and the length of the backplate. Check these measurements to make sure your new uPVC handles will fit. Lever/Lever A lever is a rod that pivots around an object. When you apply force to the end, the fulcrum will tend to turn in the direction the force is applied. This rotation multiplies your force and lets you lift or move objects that normally require more force to lift. The distance between the fulcrum of the lever and the point where you apply force determines the maximum movement. This is referred to as the mechanical advantage. The advantage of mechanical force increases when the lever is extended. You can calculate the mechanical advantage by dividing the distance from the fulcrum to the point at which you're applying the force by the distance between the fulcrum and the end of the lever. Levers can have a variety of effects based on the method by which forces are applied. For example the class 2 lever tends to rotate in the opposite direction to when the force applied to it (like a T-totter). If you push the door handle and force it to open, the forces will cause rotational effects similar to this. However, levers don't create energy. They simply multiply the force you apply by making a small amount effort across a large distance into a larger amount of force that is applied over a smaller distance. This is what enables you to complete more work in a shorter period of time, and it is why levers are often employed to lift heavy objects or moving large amounts of cargo. The lever principle is utilized in everyday tools like crowbars. hammer claws, fishing rods and your own legs, when you are standing on the hand brake of your car. Lever/Pad Lever pad handles are a kind of upvc door handle with levers on both sides to operate the multipoint lock. They are available in a variety of variations and finishes, and can be used with a variety of materials including UPVC, Aluminium & Timber doors. They are sold as a pair for the outer and inner door, with screws and spindles included. They are also available in handed and unhanded versions for different users. They are commonly used in new builds and can be installed to replace doors made of upvc. They are usually operated by lifting up the levers, which throw out all of the multipoint locks, and turning the key to close and unlock. They provide additional security compared to standard lever door handles since the locking mechanism is only accessible from the inside with a key unless the door is deadlocked. They're not as secure as a cylinder bolt however they are a reasonable option to provide extra home security. The only disadvantage is that they do not offer the same level of protection as a cylinder bolt, and consequently don't block access to outside when the door is left open. We have a wide selection of lever pad upvc handles produced by the top manufacturers in the market. They will therefore be constructed with top quality components. They are also generally supplied with a manufacturers guarantee. Typically, they will be designed to be compatible with a 92mm lock or the replacement version called a Paddock lock. They will feature an 82mm cylinder centre on the inside, and 62mm outside. They also come with two spindle followers. Some are supplied inserted in the back plate, while others can be removed to allow for different fixing centres. Lever/Snib Lever latches, the simplest of door handles are utilized. Pressing down on the lever is a simple mechanism that opens inside the door to keep it closed, which can be locked using the use of a key. The levers for privacy are in the same way, but with the addition of an Snib (like a doorknob). A snib is a very useful tool, especially in homes where security and privacy are crucial. You can use the snib button to prevent your guests from entering the home until they are ready. This type handle is also used in interior doors such as bedrooms, where you may need to restrict access from outside. In certain situations the snib button can cause problems, particularly when you have doors and locks that are bent. If the snib switch is accidentally pressed by a person who isn't familiar with it, the door may slam and lock you out. In most cases, you can be able to get in by knocking the door's frame or letterbox, however this isn't ideal. If your uPVC has a snib we recommend replacing it with a smart lock from the E-LOK 7 Series. These smart locks can be retrofitted onto double turn pull handle kits. They are available with coverplates that conceal holes that are already present to ensure a seamless installation. The E-LOK utilizes a smart app to allow you to open the door with RFID cards or mechanical keys and can be configured with passcodes to ensure security and convenience. The system has been tested to 200,000 cycles to ensure long-term durability. The handles themselves are constructed using a solid metal structure and are BS EN 1670:2007 Grade 5 for resistance to corrosion. Lever/Moveable Pad This popular handle design is commonly used on front doors. It offers the benefit of preventing the door being opened without a key from the outside in the event that the lock has not been deadlocked. This is accomplished by a 'pad' shaped external handle that locks in the gap between the handles and the lock case to stop the latch from being withdrawn or the door from being opened. This kind of handle is designed to fit uPVC doors fitted with multipoint locks that operate with split spindle operations. This kind of operation requires the lever handle and the external pad handle to be installed on the same lock case. This could be a straightforward replacement of the existing uPVC handle, but it may also require a new lock case or a new set to handle furniture. These aluminium lever/movable pads door handles are suitable for use on uPVC and feature a maintenance-free slide bearing. They also come with fixing lugs spring cassettes, and a non-stick slide bearing. These handles feature an euro-profile cut out and can be installed on various uPVC or doors made of timber. The lever moveable pad is available in various finishes to suit a wide selection of multipoint locks. They are designed to work with split spindle multipoint locks which have an 92mm cylinder center and require a specific split spindle set that is supplied by the lock manufacturer. These Hoppe London lever moveable pad handle 77G/3831N/113 are constructed of cast aluminum with an anodized surface that is corrosion resistant and scratch resistant. They can be used with various other Hoppe products including patio door handles, french door handles and window handles. They are also fitted with a security escutcheon. Lever/Moveable Snib The lever handle is one of the most popular kinds of door handles made of upvc and comes in a range of designs. It consists of two inline handles that can be moved and is lockable with either a key or thumbturn cylinder on the inside. A pad handle is an alternative to a lever/lever handle and consists of either a movable or fixed pad that can be used to operate the lock. These Fullex handles have a spring-loaded lever pad with a snib that can be triggered to hold the latch back. When choosing the right replacement upvc handle, you need to think about the screw centres and the back plate length and the PZ measurement. This will ensure that the handle works with your existing locking system. You can use our online measuring guide to help you take these measurements, so that you're sure that your new upvc handles will be an ideal fit. We offer free delivery on all orders.
