Types of UPVC Door Handles It's important to choose the correct replacement Upvc handle for your home if your handles are in need of replacement. Locksmiths can provide and install high-security uPVC handles with extra security features. The most important measurements are measurement A (known as PZ) and the length of the backplate (measurement F). Make sure to check these measurements to ensure that your new uPVC handles will fit. Lever/Lever A lever is a rigid rod that pivots around a point. 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 force and allows you to lift or move objects that would normally require more force to lift. The distance between the fulcrum of the lever and the point where you apply force determines the maximum amount of movement. upvc replacement door handles is called the mechanical advantage. The advantage in mechanical terms increases as the lever gets extended. You can calculate the advantage of mechanical by dividing the distance from fulcrum point to the point you apply force by the distance between the fulcrum's point and the end of lever. Levers can also have a variety of effects based on how the forces are applied. For example, a class 2 lever has a tendency to turn in the opposite direction when the effort force is applied (like a T-totter). If you push on the handle of a door and force it to open, the forces will cause the same rotational effects as this. However, levers don't create energy. They simply increase the force you exert by changing a small amount of effort over a large distance into a larger amount of force applied over a shorter distance. This is what enables you to accomplish more in less time, and that is why levers are commonly employed to lift heavy objects or moving large amounts of cargo. This is also the principle behind levers found in many everyday tools like crowbars, fishing rods claws for hammers and even your legs when you sit on the hand brake of your vehicle. Lever/Pad Lever pad handles, also known as upvc door handles, feature levers on both sides to operate the multipoint locks. They come in a variety of designs & finishes and can be used with a variety of materials, including UPVC, Aluminium & Timber doors. They are sold as a pair for the outer and inner door with spindles & screws included. They are also available in handed and unhanded versions for different types of users. They are commonly used in new constructions and are used to replace the existing upvc doors. They are typically operated by lifting up the levers, which throw out all of the multipoint locks before turning the key to close and unlock. They provide a bit more security than the standard lever handles for doors since locking is only done from the inside using a key. They are not as safe as a cylinder lock however they are an affordable way to increase the security of your home. The only disadvantage is that they don't have the same level of security like a cylinder bolt and therefore don't stop external access when the door is left open. We stock a large number of lever pad upvc handles produced by the top manufacturers in the industry. They are constructed with top quality components. In general, they are supplied with a manufacturer's warranty. They are typically designed to work with the 92mm lock, or a replacement model called a Paddock Lock. They will feature a cylinder with 82mm diameter on the inside and 62mm outside. They also come with two spindle followers. Some come with the backplate, and others are movable to accommodate different fixing centers. Lever/Snib Lever latches are the simplest kind of door handles. Pressing down on the lever triggers a simple latch mechanism inside the door to keep it closed, which can be locked using a key. Certain lever privacy handles work in the same way but with the addition of an snib (like knobs for doors). A snib can be very useful tool, particularly in homes where security and privacy are essential. If your partner arrives home late from work, you can use the snib button to ensure that they can't get in until they're ready in. This type handle can also be put in on doors inside, such as those in bedrooms where you want to limit access from outside. In some cases, snib buttons can cause problems, especially when you have doors and locks that are warped. If the snib button was accidentally pressed, or by someone who is not familiar with it, your door may be slammed and you locked out. Usually, you can still be able to get in by knocking the door frame or letterbox, but this isn't a good idea. If your uPVC has a snib we recommend replacing it with a smart lock from the E-LOK 7 Series. They can be retrofitted to pull handle kits that double turn and come with cover plates to hide the holes that are already present, allowing to ensure a seamless installation. The E-LOK app is able to unlock doors with RFID cards or mechanical key. Passcodes are also available for convenience and security. The system has been tested to 200 000 cycles to ensure long-term durability. The handles are made of solid metal and are in compliance with BS EN 1670 Grade 5 for corrosion resistance. Lever/Moveable Pad This popular handle design is typically used for front doors. It has the advantage of preventing the door from being opened without the key from outside in the event that the lock has not been deadlocked. This is achieved by using a 'pad-shaped' external handle that locks into the gap between the handle and the lock case. This type of handle is designed for uPVC doors that are fitted with multipoint locks which operate via a split spindle operation. This kind of operation requires that the lever handle and external pad handle be attached to the same lock case. It is a simple switch from the current uPVC handles, but it might also require a change to the lock case or a new set of handle furniture to allow for this additional functionality.

Lever-movable pads are available in a variety of finishes and can be used with a variety of multipoint locks. They are designed to work with split spindle multipoint locks which have a 92mm cylinder centre and require a specific split spindle set that is supplied by the lock maker.
