Types of UPVC Door Handles If your upvc door handle needs replacing it's essential to choose the correct replacement for your home. Locksmiths can supply 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 that your new uPVC handle will fit. Lever/Lever A lever is a rigid rod that pivots around a point. When you apply a force to the end of the lever it is likely to cause it to turn the fulcrum to the direction of the force applied. This motion increases the force and allows you to lift or move things that would normally require more force to lift. The distance between the fulcrum of the lever and the point at which you apply force determines the maximum movement. This is known as the mechanical advantage. The more the lever is extended more, the greater the advantage in terms of mechanical. You can calculate the advantage of mechanical by dividing distance from the fulcrum point to the point at which you are applying force by the distance between fulcrum point and the end of lever. Levers also have various effects based on the way in which forces are applied. For instance a lever of class 2 tends to rotate in the opposite direction to when the force of effort is applied (like a teeter-totter). The forces created by pushing the handle of a front door can create rotational effects similar to those. However, levers don't create energy. They just multiply the force you exert by making a small amount effort over a large distance into a greater amount of force applied over a shorter distance. This is what allows you to accomplish more in less time, which is the reason why levers are frequently used to lift heavy objects or moving large quantities of cargo. This is also the basis behind the levers you find in a variety of everyday tools such as crowbars and fishing rods, hammer claws and even your legs when you sit on the hand brakes of your car. Lever/Pad Lever pad handles are a form of door handle made of upvc with levers on both sides that operate the multipoint lock. These come in many variations & finishes and are suitable for a range of materials like UPVC, Aluminium & Timber doors. They are sold as a pair for the inner and outer door, with screws and spindles included. They are also available in hand and unhanded versions for different users. They are commonly used in new constructions and can be fitted to replace existing doors made of upvc. They are usually operated by lifting up 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 standard lever door handles since locking can only be performed through the inside with keys. They're not as secure as a cylinder bolt but are an affordable alternative for a home with more security. The only disadvantage is that they don't provide the same level of security as a cylinder lock and they don't restrict access to the home if the door is left open. We stock a large number of lever pad upvc handles manufactured by leading manufacturers in the field. They will therefore be constructed with top quality components. They are also generally supplied with a manufacturer's warranty. They usually are designed to work with the 92mm lock, or a substitute version known as the Paddock Lock. They will feature a 92mm cylinder center on the inside and 62mm on the exterior and be fitted with 2 spindle followers. Some come with a backplate in place, while others are movable to accommodate different fixing centers. Lever/Snib Lever latches, the simplest of door handles are commonly used. The lever is pushed downwards to operate a simple latch inside the door, which can be locked using a key. The levers for privacy are based on this same principle however, with the addition of an Snib (like knobs for doors). A snib is a very useful tool, particularly in homes where privacy and security are important. You can use the snib button to block your guest from entering until they are ready. This kind of handle can also be put in on doors inside, such as those in bedrooms, where you wish to restrict outside access. In certain situations, snib buttons can cause problems, especially if you have older locks or doors that are distorted. If the snib button is used in a mistake or by someone who isn't used to it, the door could slam shut and lock you out. You can usually get in by knocking on the door frame or the letterbox. But this isn't a good idea. 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 come with coverplates to hide existing holes to ensure an easy installation. The E-LOK uses a smart app to enable you to unlock the door with mechanical keys or RFID cards and can 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 themselves are constructed using a solid metal structure 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 is advantageous because it has the benefit of preventing the door from being opened without the key from outside when the lock hasn't been deadlocked. This is achieved with a 'pad-shaped' external handle that locks into the gap between the handle and lock case. This type of handle is designed to fit uPVC doors with multipoint locks which operate via split spindle operations. This kind of operation requires that the internal lever handle and external pad handle be attached to the same lock case. This can be a simple replacement of the existing uPVC handle, however it may also require a lock case change or a new set of handles to handle furniture. These aluminum lever/movable pads door handles are suitable to be used on uPVC and feature an easy-to-maintain slide bearing. They also come with fixing lugs spring cassettes, and an unstick slide bearing. These handles have an euro-profile cut out and can be mounted on various uPVC or timber doors. Lever moveable pads are offered in a variety of finishes to can be used with a variety of multipoint locks. They are designed to work with split spindle locks with the 92mm cylinder as their centre and require a separate set of split spindles provided by the lock maker. These Hoppe London 77G/3831N/113 lever moveable pad handles are made from cast aluminum with an anodised surface that is resistant to corrosion and high scratch resistance. These handles can be used in combination with other Hoppe products, including patio door handles. french door handles and window handles for windows. They also have a security escutcheon. Lever/Moveable Snib The lever/lever handle is among the most sought-after kinds of door handles made of upvc and comes in a variety of designs. It is comprised of two inline handles that can be moved and locked with a thumbturn cylinder or a key. Pad handles can be used as an alternative to lever handles. It is comprised of a fixed or moveable pad which can be used to operate locks. These Fullex handles have a spring-loaded lever pads with snibs that can be activated to hold the latch back.
