Types of UPVC Door Handles It is essential to select the correct replacement Upvc handle for your home if your upvc handles need replacing. Locksmiths can provide and fit high-security uPVC handles with extra security features. The most important measurements to consider are the measurement A (also known as PZ) and the length of the backplate. Make sure to check these measurements to ensure that your new uPVC handles will fit. Lever/Lever A lever is a rod that pivots around an object. When you apply force towards the end, the fulcrum is likely to move in the direction of the force is applied. This rotates the fulcrum, increasing the applied force, allowing you to lift or move something that would require more force if you tried to apply directly to the load. The distance between the fulcrum to the point where you apply the force determines the distance the lever is able to move. This is referred to as the mechanical advantage. The mechanical advantage increases as the lever is extended. You can calculate the advantage by dividing the distance from the fulcrum until the point at which you are applying the force by the distance between the fulcrum and where you will end the lever. Levers can have different effects based on the method by which forces are applied. A lever of class 2 for instance, has a tendency of rotating in the opposite direction once the effort force is applied. The forces produced by pushing the handle of a front door will produce rotational effects that are similar to those. However, levers don't create energy. They simply multiply the force you exert by changing a small amount of effort applied over a long distance into a larger amount of force applied over a smaller distance. This is what enables you to do more work in a shorter period of time, and that is why levers are commonly used for lifting heavy objects or moving large quantities of cargo. This is also the basis behind the levers that are found in many everyday tools like crowbars and fishing rods, hammer claws and even your legs when you sit on the hand brake of your vehicle. Lever/Pad Lever pad handles are a type of door handle made from UPVC with levers on both sides to operate the multipoint lock. These are available in a variety of finishes & variations and can be installed on a wide range of materials that include UPVC doors, Aluminium doors & Timber Doors. They are sold in pairs for the outside and the interior doors 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 existing upvc doors. 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 offer a little more security than the standard lever handles for doors because locking can only be performed from the inside using a key. They're not as secure as a cylinder bolt but are a cost-effective alternative for a home with more security. The only disadvantage is that they don't have the same level of security like 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 top manufacturers in the industry and will be manufactured with good 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 also come with two spindle followers. Some come with the backplate, and others can be removed to accommodate different fixing centers. Lever/Snib Lever latches, which are the simplest of all door handles, are used. By pressing down on the lever, it is a simple mechanism that opens inside to keep the door closed, which can be locked with a key. The levers for privacy are in the same way but with the addition of an Snib (like knobs for doors). A snib-button can be extremely useful, particularly for homes where it's important to maintain privacy or security. If your partner arrives at home late from work, you can utilize the snib button to ensure that they aren't allowed in until they're ready to come in. This kind handle is also used in doors that are inside, such as bedrooms, where you may require a lock to prevent access from the outside. In certain situations, snib buttons can cause problems, especially in the case of doors and locks that are distorted. If the snib button is used in a mistake or by someone who isn't accustomed to it, the door may close and lock you out. It is possible to gain entry by knocking the door frame or letterbox. But, this is not 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 pull handle kits that double turn and are available with cover plates to conceal existing holes for a seamless install. The E-LOK uses a smart app that allows you to unlock the door using RFID cards or mechanical keys and is able to be set up with passcodes for safe entry and convenience. The system has been tested for 200,000 times to ensure long-lasting durability. The handles themselves are made with a solid-metal construction and are BS EN 1670:2007 Grade 5 for corrosion resistance. Lever/Moveable Pad This popular handle design is typically used for front doors. It offers the benefit of preventing the door being opened without the key from outside in the event that the lock has not been deadlocked. This is achieved by using the 'pad-shaped' handle that locks into the gap between the handle and the lock case. This type of handle is designed to fit uPVC doors fitted with multipoint locks which operate via split spindle operations. This type of operation requires that the internal lever handle and external pad handle both be fitted to the same lock case. It is a simple switch from the current uPVC handles, but it could also require changing the lock case or a brand new set of handles to accommodate this additional function. These levers/movable pad handles are suitable for uPVC doors. They feature an easy to maintain slide bearing, spring cassettes and fixing lugs provided. They have a euro profile cut out and are installed to a variety of uPVC and timber doors. Lever moveable pads are offered in a variety of finishes to suit many different multipoint locks. They are designed to be used with split spindle multipoint locks with a 92mm cylinder centre and require a separate split spindle set, as supplied by the lock manufacturer. These Hoppe London 77G/3831N/113 lever moveable pad handles are manufactured from cast aluminum with an anodised finish that is resistant to corrosion and has high scratch resistance. These handles can be used in conjunction with many other Hoppe products, such as patio door handles . french door handles and window handles. They also include an escutcheon for security. Lever/Moveable Snib Lever handles are among the most popular types of upvc doors handles. They come in many designs. It is made up of two inline handles that can be locked and moved using a thumbturn cylinder or keys. Pad handles can be used as a substitute to lever handles. It is comprised of one that is fixed or moveable which can be used to operate the lock. These Fullex handles are sprung lever pads that have a snib that can be turned on to hold the latch back. When choosing a replacement upvc handle, you need to consider the screw centres, the back plate length, and the PZ measurement. This will ensure that the handle works with your existing locking system.
