Types of UPVC Door Handles It is essential to select the right replacement upvc handle for your home when your handles made of upvc require replacement. A locksmith can supply and fit high-security uPVC 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. Check these measurements to ensure that your new uPVC handle will fit. Lever/Lever A lever is a rod that pivots around a point. When you apply force to the end of the bar, the fulcrum will turn in the direction 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 it directly to the load. The distance between the fulcrum to the point where you apply the force determines the distance the lever can move. This is called the mechanical advantage. The advantage of mechanical force increases as the lever gets extended. You can calculate the advantage of mechanical by dividing distance from fulcrum point to the point at which you are applying force by distance between the fulcrum point and end of the lever. Levers also have various effects depending on how the 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 T-totter). If you push on the door handle and force it to open, the forces will cause rotational effects similar to this. However, levers don't create energy. Levers multiply the force by converting small amounts of effort applied over a lengthy distance into larger amounts of force applied over smaller distances. This allows you to complete more work in a shorter amount of time, and that is why levers are often used for lifting heavy objects or moving large quantities of cargo. This is also the principle behind the levers that are found in many everyday tools such as crowbars, fishing rods, hammer claws and even your legs when you sit on the hand brake of your vehicle. Lever/Pad Lever pad handles, also referred to as upvc door handles, feature levers on both sides to operate the multipoint locks. These come in many variations & finishes and are suitable for a variety of materials including UPVC, Aluminium & Timber doors. They are sold in pairs for the outer and inner door with spindles & screws included. They are also available in both handed and unhanded versions for different types of users. These locks can be used to replace the existing upvc door. They are usually operated by lifting the levers to throw out all of the multipoint locks and turning the key to close and unlock. They provide additional security in comparison to traditional lever door handles because the locking function can only be gained via the inside using keys unless the door is locked. They're not as secure as a cylinder lock, but they are an affordable way to provide extra security to your home. The only disadvantage is that they do not offer the same level of protection like a cylinder bolt and consequently don't block access to outside if the door has been left open. The majority of lever pad upvc door handle s we offer are manufactured by industry's leading manufacturers and therefore are made from high quality components. In general, they come with a manufacturer's warranty. They usually are designed to work with the 92mm lock, or a replacement model called a Paddock Lock. They will have a 92mm cylinder centre on the inside and 62mm on the exterior and be fitted with 2 spindle followers. Some are inserted into the back plate whilst others can be removed to allow for different fixing centres. Lever/Snib Lever latches are the simplest kind of door handles. The lever is pulled down to activate a simple latch inside the door. It can be locked with keys. The levers for privacy are using the same principle however, with the addition of a snib (like knobs for doors). A snib is a extremely useful tool, particularly in homes where privacy and security are crucial. If your spouse is expected to arrive at home late from work, you can utilize the snib so that they can't get in until they're ready in. This type of handle is also popular in interior doors, such as bedrooms, where you may need to restrict access from the outside. In some instances there are instances where snib buttons could cause problems, particularly in the case of older locks and doors that are bent. If the snib is applied accidentally or by a person who isn't quite used to it, the door may slam shut and lock you out. It is possible to gain entry by knocking on the door frame or letterbox. But this isn't a good idea. If your uPVC door has a snib lock it is recommended to replace the handle with an modern E-LOK 7-Series smart lock. These smart locks can be retrofitted to double-turn pull handle kits. They come with coverplates to hide holes that are already present for a seamless installation. The E-LOK makes use of a smart application to allow you to open the door with RFID cards or mechanical keys and is able to be set up with passcodes for secure entry and convenience. The system has been tested for 200,000 cycles to ensure long-lasting durability. The handles themselves are constructed using a solid metal structure and are BS EN 1670:2007 Grade 5 for resistance to corrosion. Lever/Moveable Pad This popular style of handle is typically used for front doors. It has the advantage of preventing the door being opened without the key from outside when the lock hasn't been deadlocked. This is achieved by the 'pad'-shaped external handle which locks in the gap between the handles and the lock case to prevent the latch from being pulled back or the door opened. This handle is designed to be used with uPVC multipoint locks that use split spindle mechanisms. This kind of operation requires that the internal lever handle and the external pad handle are both fitted to the same lock case. This can be a simple replacement for the current uPVC handle, however it could also require a lock case change or a new set of handles to handle furniture. These aluminum levers and movable pad door handles are ideal for uPVC doors and come with a maintenance free slide bearing fixing lugs, spring cassettes and fixing lugs supplied. They feature a euro-style cut out and are fitted to a variety of uPVC and timber doors. The lever-movable pad is available in many styles to match a wide variety of multipoint locks. They are designed for use with split spindle locks which have an 92mm centre cylinder and require a specific set of split spindles provided by the manufacturer of the lock. These Hoppe London lever moveable pad handle 77G/3831N/113 are constructed of cast aluminum with an anodized finish that is scratch and corrosion resistant. They can be used in conjunction with various other Hoppe products like patio door handles, french door handles, and window handles and come complete with a security escutcheon. Lever/Moveable Snib Lever handles are among the most popular types of upvc doors handles. They are available in various designs. It consists of two moveable inline handles and can be locked with either a key or a thumbturn cylinder on the inside. A pad handle is an alternative to a lever/lever handle and consists of either a movable or fixed pad that can be used to operate the lock. These Fullex handles have a spring-loaded lever pads that have a snib that can be turned on to stop the latch from closing.
