Types of UPVC Door Handles When your upvc door handle 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 to take are the measurement A (also called PZ) as well as the length of the backplate. Please check these measurements to ensure that your new uPVC handles will fit. Lever/Lever A lever is a solid bar that pivots around a central point (known as a the fulcrum). When you apply a force at the end of the lever it tends to rotate the fulcrum in the direction of the force. This rotation multiplies the applied force which 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 of the lever and the point where you apply force determines the maximum movement. This is known as the mechanical advantage. The mechanical advantage increases as the lever gets extended. You can calculate the advantage by dividing the distance from the fulcrum to the point where you are applying the force by the distance between the fulcrum and where you will end the lever. Levers can have a variety of effects based on the method by which forces are applied. A class 2 lever, for example, has a tendency of rotating in the opposite direction when an force of the effort is applied. The forces produced by pushing the handle of a front door will create rotational effects similar to those. However, levers don't create energy. Levers multiply the force by changing small amounts of effort applied over a lengthy distance into larger amounts of force applied over shorter distances. Levers are used to lift heavy objects and move large amounts of cargo. This is also the reason behind levers found in many everyday tools such as crowbars and fishing rods, claws for hammers and even your own legs when you stand on the hand brake of your car. Lever/Pad Lever pad handles, also referred to as upvc door handles, have levers on each side to operate the multipoint locks. Lever pad handles are available in various finishes and variations and can be used on a variety of materials that include 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 to suit different types of users. They are commonly used in new constructions and can be fitted to replace existing doors made of upvc. They are typically operated by lifting the levers to throw all of the multipoint locks and turning the key to close / unlock. They offer a little more security than standard lever door handles, as the locking can only be done from the inside using keys. They're not as secure as a cylinder lock, however they are cost-effective ways to provide extra security to your home. The only downside is that they don't have the same level of protection as a cylinder bolt, and therefore don't stop external access if the door has been left open. The majority of the lever pad door handles made of upvc that we stock are made by the leading manufacturers in the industry, and are constructed using high quality components. In general, they come with a manufacturer's warranty. These are usually designed to work with the 92mm lock, or a replacement model called the Paddock Lock. They will feature a 92mm cylinder center on the inside and 62mm on the outside. They will also be fitted with 2 spindle followers. Some are supplied inserted in the back plate, while others are removable to allow for different fixing centers. Lever/Snib Lever latches are the most basic type of door handles. By pressing down on the lever, it triggers a simple latch mechanism inside to keep the door closed, which can be locked using the use of a key. Some lever privacy handles operate based on this same principle however, with the addition of an Snib (like the doorknob). A snib-button can be very beneficial, especially in homes where it's essential to maintain privacy or security. If your spouse is expected to arrive home late from work, you can apply the snib so that they won't be able to enter until they're ready to come in. This type of handle is also popular for interior doors, such as bedrooms, where you may need to restrict access from the outside. upvc replacement door handles can cause issues in some cases, especially when you have old locks and doors that are warped. If the snib switch is accidentally pressed or by a person who isn't familiar with it, your door may slam and lock you out. You can usually get in by knocking on the door frame or the letterbox. However this isn't a good idea. If your uPVC door has a snib button it is recommended to replace the handle with a modern E-LOK 7-Series smart lock. They can be retrofitted to pull handle kits that double turn and come with cover plates that hide existing holes, to ensure a seamless installation. The E-LOK uses a smart app to allow you to open the door using mechanical keys or RFID cards and can be configured with passcodes for safe entry and convenience. The system has been tested to 200 000 cycles to ensure long-term 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 popular handle style is typically used for front doors. It is advantageous because it has 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 achieved with the 'pad-shaped' handle that locks into the gap between the handle and lock case. This handle is designed to work with uPVC multipoint locks which use a split spindle mechanism. This type of operation requires that the lever handle and the external pad handle both be fitted to the same lock case. This could be a straightforward switch from the current uPVC handles, but it might also require changing the lock case or even a new set of handle furniture to allow for this additional functionality. These aluminum levers and movable pads door handles are able 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 have an euro-profile cut out and can be mounted on various uPVC or doors made of timber. The lever moveable pad is available in various styles to match a wide variety of 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 lock maker.

They can be used with a wide variety of other Hoppe products, including patio door handles, french door handles, and window handles. They come with an escutcheon for security. Lever/Moveable Snib The lever/lever handles are among the most popular kinds of doors handles made of upvc. They are available in a variety of styles. It consists of two inline handles that can be moved and is lockable with either a key or thumbturn cylinder on the inside. Pad handles are an alternative to a lever/lever handle. It is made up of either a movable or fixed pad that can be used to operate the lock. These Fullex handles have a sprung lever pad and a snib that can be turned on to secure the latch.
