Types of UPVC Door Handles If your door handle made of uPVC is in need of replacement, it's important to find the right replacement for your home. Locksmiths can supply and install high-security uPVC door handles that come with additional security features. The most important measurements you should take are the measurement A (also called PZ) as well as the length of the backplate. Take these measurements to make sure that your new uPVC handle will fit. Lever/Lever A lever is a solid bar that is pivotally positioned around a point (known as a the fulcrum). When you apply a 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 otherwise require more force to lift. The distance between the fulcrum and the place where you apply the force determines how far the lever is able to move. This is referred to as the mechanical advantage. The more the lever extends more, the greater the mechanical advantage. You can determine the mechanical advantage by dividing the distance from the fulcrum to the point where you are applying the force by the distance between the fulcrum and the end of the lever. Levers can produce different effects based on the method by which forces are applied. For example, a class 2 lever is inclined to turn in the opposite direction as the force of effort is applied (like a totter-totter). The forces produced by pushing on the handle of a front door can produce rotational effects that are similar to those. However, levers don't create energy. They just multiply the force you apply by converting a small amount of effort applied over a long distance into a larger amount of force that is applied over a smaller distance. Levers are used to lift heavy objects and move massive amounts of cargo. The principle of the lever is also employed in everyday tools such as crowbars. hammer claws fishing rods, hammer claws, and your own legs when you stand on your car's hand brake. Lever/Pad Lever pad handles, also referred to as upvc door handles , feature levers on both sides to operate the multipoint locks. Lever pad handles are available in a variety of finishes & designs and can be used on a variety of materials such as UPVC doors, Aluminium doors & Timber Doors. They are sold in pairs for both the inner and exterior door with screws and spindles included. They are available in both hand and unhandled versions to suit different users. They are commonly used in new constructions and are used to replace the doors made of upvc. The levers are lifted to open the multipoint locks, and the key is turned to lock or close the door. They provide a bit more security than traditional lever door handles since locking can only be done from the inside using a key. They are not as secure as a cylinder bolt however they are a cost-effective option to provide extra home security. The only disadvantage is that they don't have the same level of security as a cylinder bolt, and consequently don't block access to outside in the event that the door has been left open. The majority of the lever pad door handles made of upvc that we have in stock are manufactured by the industry's leading manufacturers and therefore are made from high quality components. In general, they come with a manufacturer's guarantee. Typically, they are designed to be compatible with a 92mm lock, or the 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 inserted into the back plate, while others can be removed to enable different fixing centres. Lever/Snib Lever latches are the most basic of door handles are used. The lever is pushed down to activate a simple latch inside the door that can be locked using keys. The levers for privacy are based on this same principle, but with the addition of the lock snib (like the doorknob). A snib can be a very useful tool, especially in homes where security and privacy are crucial. You can use the snib handle to block your guests from entering the home until they are ready. This kind of handle is also popular in interior doors such as bedrooms, where you might want to restrict access from the outside. Snib buttons may cause problems in some cases, especially when you have locks that are old and doors that are warped. If the snib button was accidentally pressed or by someone who is not familiar with it, the door may slam and lock you out. Most of the time, you can get in by knocking on the door's frame or letterbox, however this isn't ideal. If your uPVC has a snib we recommend replacing it with an electronic lock from the E-LOK 7 Series. These can be retrofitted over double turn pull handle kits and are available with cover plates to conceal existing holes, to ensure a seamless installation. The E-LOK app can be used to open doors using RFID cards or a mechanical key. Passcodes are also offered to ensure security and convenience. The system has been tested for 200,000 cycles to ensure its durability. The handles themselves are constructed with a solid metal construction and are BS EN 1670:2007 Grade 5 for resistance to corrosion. Lever/Moveable Pad This popular handle style is commonly used on front doors. It is advantageous because it has the benefit of preventing the door being opened without the key from outside when the lock hasn't been deadlocked. This is accomplished through a 'pad' shaped external handle that locks into the gap between the handles and lock case to prevent the latch from being removed or the door opened. This handle is designed to work with uPVC multipoint locks that employ split spindle mechanisms. This kind of operation requires the lever handle as well as the external pad handle to be fitted on the same lock case. It is a simple change from the current uPVC handles, but it might also involve changing the lock case or a new set of handle furniture to allow for this additional functionality. These aluminium lever/movable pads door handles are suitable to be used on uPVC and come with an easy-to-maintain slide bearing. They also come with fixing lugs spring cassettes, and a non-stick slide bearing. These handles feature a cut-out for a euro-profile, and can be fitted to various uPVC or doors made of timber. The lever moveable pad is available in many finishes to suit a wide variety of multipoint locks. They are specifically designed to be used with split spindle locks that have the 92mm cylinder as their centre and require a specific set of split spindles supplied by the manufacturer of the lock. These Hoppe London lever moveable pad handle 77G/3831N/113 are made from cast aluminum with an anodized surface that is corrosion resistant and scratch resistant. These handles can be used in combination with other Hoppe products, including patio door handles. french door handles, and window handles. They also have a security escutcheon. Lever/Moveable Snib Lever handles are one of the most popular kinds of upvc door handles. They are available in a variety of designs. It consists of two handles that can be locked and moved by a thumbturn cylinder, or the use of a key. A pad handle is an alternative to a lever or lever handle. It consists of an adjustable or fixed pad that can be used to operate the lock. These Fullex handles are sprung lever pads that have a snib that can be activated to hold the latch back.
