Types of UPVC Door Handles If your door handle made of uPVC needs replacing it's essential to find the right replacement for your home. 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). Please check these measurements to ensure your new uPVC handles will fit. Lever/Lever A lever is a solid bar that pivots around a central point (known as a fulcrum). When you apply force to the end of the lever it tends to rotate the fulcrum to the direction of the applied force. This rotates the force and lets you lift or move objects 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 called the mechanical advantage. The greater the length of the lever the greater the mechanical benefit. You can determine 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 where you will end the lever. Levers can produce different effects based on the method by which the force is applied. A lever of class 2 for instance, has a tendency of turning in the opposite direction when the effort force is applied. If you push on the handle of a door, the forces will produce the same rotational effects as this. However, levers don't create energy. Levers multiply the force by converting small amounts of effort applied over a longer distance into larger amounts of force applied over shorter distances. Levers are used to lift heavy objects and transport huge quantities of cargo. This is also the reason behind the levers you find in a variety of everyday tools such as crowbars, fishing rods, claws for hammers, and even your legs when you sit 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. They are available in a variety of variations & 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 screws and spindles included. They are also available in handed and unhanded versions for different users. These are often used for new constructions and are fitted to replace existing doors made of upvc. The levers are raised to open all multipoint locks and the key is turned to lock or close the door. They are more secure when compared to standard lever door handles because the locking function is only accessible via the inside using an open key, in the event that the door is locked. They're not as secure as a cylinder lock, however they are an affordable way to provide extra security to your home. The only drawback is that they don't have the same level of protection as a cylinder bolt and therefore won't prevent access from outside in the event that the door has been left open. The majority of the lever pad upvc door handles that we have in stock are manufactured by the industry's leading manufacturers and therefore will be manufactured with good quality components. In general, they come with a manufacturer's guarantee. They usually are designed to work with the 92mm lock or a replacement version called a Paddock Lock. They will have an 82mm cylinder center on the inside and 62mm outside. They are also fitted with two spindle followers. Some are fitted with the back plate while others are removable to allow for different fixing centres. Lever/Snib Lever latches, the simplest of door handles are utilized. The lever is pushed downwards to activate a simple latch inside the door that can be locked using keys. Certain lever privacy handles work in the same way but with the addition of an lock snib (like a doorknob). A snib can be very useful tool, especially in homes where privacy and security are essential. If your partner is arriving home late from work, you can use the snib so that they can't get in until they're ready in. This kind handle can also be used for doors in the interior, like those in bedrooms where you want to restrict access from outside. Snib buttons may cause problems in certain circumstances, 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 used to it, the door can slam shut and shut you out. You can usually gain entry by knocking on the door frame or letterbox. However this isn't a good idea. If your uPVC has a snib, we recommend replacing it with a smart lock from the E-LOK 7 Series. These can be retrofitted over double turn pull handle kits and come with cover plates to conceal existing holes for a seamless install. The E-LOK makes use of a smart application that allows you to unlock the door using RFID cards or mechanical keys, and can be configured with passcodes for secure entry and convenience. The system has been tested for 200,000 cycles in order to ensure its durability. The handles themselves are made using a solid metal structure and are BS EN 1670:2007 Grade 5 for resistance to corrosion. Lever/Moveable Pad This is a popular handle style for front doors. It has the benefit of preventing the door from being opened by the outside without a key if the lock is not deadlocked. This is accomplished through an external 'pad' handle which locks in the gap between the handles and the lock case to stop the latch from being withdrawn or the door opened. This handle is designed to be used with uPVC multipoint locks that use a split spindle mechanism. This type of operation requires that the 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 may also require a lock case change or a new set of handles to handle furniture. These levers/movable pad door handles are ideal for uPVC doors and feature a maintenance free slide bearing as well as fixing lugs and spring cassettes supplied. These handles feature an euro-profile cut out and can be installed on many uPVC or doors made of timber. Lever moveable pads are available in various finishes and suit many different multipoint locks. They are specifically designed to be used with split spindle locks that have an 92mm centre cylinder and require a specific set of split spindles supplied by the manufacturer of the lock.

These handles can be used in combination with other Hoppe products, including patio door handles. french door handles, and window handles. window handles www.repairmywindowsanddoors.co.uk have a security escutcheon. Lever/Moveable Snib The lever handles are one of the most popular types of upvc doors handles. They are available in a variety of styles.
