Types of UPVC Door Handles It's important to choose the correct replacement Upvc handle for your home if handles are in need of replacement. A locksmith can offer and install high-security uPVC door handles with extra security features. The most important measurements are measurement A (known as PZ) and the length of the backplate (measurement F). Check these measurements to ensure that your new uPVC handles will fit. Lever/Lever A lever is a rod that pivots around a point. 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 and allows 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 of the lever and the point where you apply force determines the maximum amount of movement. This is referred to as the mechanical advantage. The greater the length of the lever more, the greater the mechanical advantage. You can calculate the advantage of mechanical by dividing the distance from fulcrum point to the place where you are applying force by distance between fulcrum point and the end of 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 the force of the effort is applied. If you press on the door's handle the force will create the same rotational effects as this. However, levers don't create energy. They multiply the force by making small amounts of effort applied over a lengthy distance into larger amounts of force applied over shorter distances. This is what enables you to complete more work in a shorter period of time, which is why levers are often employed to lift heavy objects or moving large quantities of cargo. This is also the reason behind levers found in many everyday tools, such as crowbars, fishing rods, claws for hammers and even your legs when you sit on the hand brakes 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. They are available in a variety of variations & finishes and are suitable for a variety of materials like UPVC, Aluminium & 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 both handed and unhandled versions for different users. They are commonly used in new constructions and can be used to replace the doors made of upvc. The levers are raised to open all multipoint locks, and the key is turned to close or unlock the door. They provide a bit more security than traditional lever door handles, as the locking is only done through the inside with a key. They are not as safe as a cylinder lock, however they are an affordable way to provide extra security to your home. The only downside is that they do not offer the same level of protection as a cylinder lock and they don't restrict access to the home if the door is left open. The majority of lever pad upvc door handles we offer are manufactured by top manufacturers in the industry and will be manufactured with good quality components. They also come with a manufacturer's guarantee. These are usually designed to work with the 92mm lock or a substitute version known as the 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 come with the backplate in place, while others are removable for different fixing centers. Lever/Snib Lever latches are by far the most simple kind of door handles. Pushing down on the lever triggers a simple latch mechanism inside to keep the door closed. It can also be locked with keys. Some lever privacy handles work similar to the doorknob, but with an additional snib, which is similar to the doorknob. A snib can be extremely useful tool, particularly in homes where security and privacy are essential. You can use the snib button to stop your partner from entering until they are prepared. This kind of handle is also popular for interior doors, such as bedrooms, where you may require a lock to prevent access from outside. In some instances, snib buttons can cause problems, especially in the case of older locks and doors that are bent. If the snib button is accidentally pressed, or by someone who is not familiar with it, the door may shut and lock you out. Usually, you can still gain entry by knocking on the door frame or the letterbox, but this isn't a good idea. If your uPVC door is equipped with a snib-button, we recommend replacing the handle with an modern E-LOK 7-Series smart lock. These smart locks can be retrofitted to double-turn pull handle kits. They are available with coverplates that conceal the holes in the existing ones to make it a seamless installation. The E-LOK uses a smart app to allow you to open the door with RFID cards or mechanical keys, and can be set up with passcodes for secure entry and convenience. The system has been tested for 200,000 times to ensure durability. The handles are made of solid metal and are in compliance with BS EN 1670 Grade 5 for resistance to corrosion. Lever/Moveable Pad This popular handle design is commonly used on front doors. It has the advantage of preventing the door from being opened without an outside key in the event that the lock has not been deadlocked. This is accomplished through an external 'pad' handle which locks in the gap between the handles and lock case to stop the latch from being pulled back or the door from being opened. This handle is designed to work with uPVC multipoint locks that use split spindle mechanisms. This kind of operation requires the internal lever handle as well as the external pad handle to be fitted 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 brand new set to handle furniture.

They are designed to be used with split spindle multipoint locks that have a 92mm cylinder centre and require a special split spindle set as supplied by the lock manufacturer.
