Types of UPVC Door Handles It is crucial to select the correct replacement Upvc handle for your home if upvc handles need replacing. A locksmith can supply and fit high-security uPVC handles that come with additional security features. The most important measurements are measurement A (known as PZ) and the length of the backplate (measurement F). Make upvc door handle www.repairmywindowsanddoors.co.uk to check these measurements to make sure your new uPVC handles 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 at the end of the lever it tends to rotate the fulcrum in the direction of the force applied. This motion increases the applied force and allows you to lift or move something that would require a greater amount of force if you attempted to apply directly to the load. The distance between the fulcrum and the place where you apply the force determines how far the lever can move. This is referred to as the mechanical advantage. The more the lever is extended, the larger the mechanical advantage. You can calculate the mechanical advantage by dividing distance from fulcrum point to the point you are applying force by distance between the fulcrum's point and the end of the lever. Levers can also have different effects depending on how the forces are applied. For instance a lever of class 2 is inclined to turn in the opposite direction when the effort force is applied (like a T-totter). The forces created when you push on the handle of a front door will result in rotational effects similar to these. However, levers don't create energy. They just multiply the force you exert by changing 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 transport huge amounts of cargo. This is also the basis behind the levers you find in a variety of everyday tools such as crowbars, 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 feature levers on both sides to operate the multipoint locks. These come in many variations and finishes and can be used with a variety of materials like UPVC, Aluminium & Timber doors. They are sold in pairs for the inner and outer door, with screws and spindles included. They are available in both hand- and non-handled versions to meet the needs of different users. These are often used for new constructions and are used to replace the existing upvc doors. They are typically operated by lifting up the levers to throw all of the multipoint locks before turning the key to close or unlock. They offer some extra security when compared to standard lever door handles since the locking mechanism can only be accessed via the inside using an open key, in the event that the door is locked. They're not as secure as a cylinder bolt however they are an affordable alternative to add security. The only disadvantage is that they do not offer the same level of protection as a cylinder bolt and therefore don't stop external access when the door is 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 will be manufactured with good quality components. In general, they come with a manufacturer's warranty. They usually are designed to work with the 92mm lock or a substitute version known as a Paddock Lock. They will have a 92mm centre cylinder on the inside and 62mm on the exterior and be fitted with 2 spindle followers. Some are inserted into the back plate, while others are removable to enable different fixing centres. Lever/Snib Lever latches are the simplest type of door handles. The lever is pushed down to operate a simple latch inside the door. It can be locked with a key. Certain lever privacy handles operate in the same way, but with a second snib, similar to the doorknob. A snib-button can be very useful, especially in homes where it's essential to ensure privacy or security. If your partner is arriving at home late from work, you can use the snib to ensure 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 might want to restrict access from outside. In certain situations, snib buttons can cause problems, especially when you have doors and locks that are warped. If the snib switch is accidentally pressed or by a person who isn't familiar with it, the door may shut and lock you out. In most cases, you can be able to get in by knocking the door frame or the letterbox, but this isn't ideal. If your uPVC door is equipped with a snib-button, we recommend replacing the handle with a contemporary E-LOK 7-Series smart lock. These smart locks can be retrofitted to double-turn pull handle kits. They are available with coverplates that hide the holes in the existing ones for an easy installation. The E-LOK application is able to unlock 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 long-lasting durability. The handles are made of solid metal and comply with BS EN 1670 Grade 5 for corrosion resistance. Lever/Moveable Pad This popular handle design is commonly used on front doors. It is advantageous because it has the benefit of preventing the door from being opened without a key from the outside in the event that the lock has not been deadlocked. This is achieved by using an external handle that is shaped like a pad that locks into the gap between the handle and lock case. This handle is designed to work with uPVC multipoint locks that use split spindle mechanisms. This type of operation requires the lever handle and the external pad handle to be mounted to the same lock case. This could be a straightforward replacement for the current uPVC handle, but it could also require a lock case change or a new set to handle furniture.
