Types of UPVC Door Handles
If your upvc door handle is in need of replacement, it's important to find the right replacement for your home. 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 make sure that your new uPVC handles will fit.
Lever/Lever
A lever is a rigid rod that pivots around the point. When you apply force to the end of the bar, the fulcrum will tend to rotate in the direction that the force is applied. This rotation multiplies the applied force, allowing you to lift or move something that would require more force if you attempted to apply directly to the load.
The distance between the fulcrum and the point where you apply the force determines the distance the lever can move. This is referred to as the mechanical advantage. The advantage of mechanical force increases as the lever is extended. You can calculate the mechanical advantage by dividing distance from the fulcrum point to the place where you apply force by the distance between the fulcrum's point and the end of lever.
Levers can have different effects based on the method by which forces are applied. A class 2 lever, for example, has a tendency of turning in the opposite direction when an effort force is applied. If you push on the door handle, the forces will produce the same rotational effects as this.
However, levers don't create energy. Levers multiply the force by converting small amounts of effort applied over a longer distance into greater amounts of force applied over smaller distances. This is what enables you to complete more work in less time, and it is why levers are commonly employed to lift heavy objects or moving large quantities of cargo. This is also the basis behind levers found in many everyday tools like 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 known as upvc door handles, feature levers on both sides to operate the multipoint locks. They come in a variety of designs and finishes and can be used with a variety of materials including UPVC, Aluminium & Timber doors. They are sold in pairs for the inner and outer door with spindles & screws included. They are also available in handed and unhanded versions for different users.
They are typically used for new constructions and can be used to replace the doors made of upvc. The levers are lifted to open the multipoint locks, and the key is turned to lock or close the door. They offer some extra security compared to traditional lever door handles as the locking operation is only accessible by entering the door with keys unless the door is locked.
They're not as secure as a cylinder lock however they are a cost-effective way to provide extra security to your home. The only disadvantage is that they don't offer the same level of protection like a cylinder bolt and therefore won't prevent access from outside if the door has been left open.
We stock a variety of lever pad upvc handles produced by the top manufacturers in the field. They are made with high quality components. In general, they are supplied with a manufacturer's guarantee.
Typically, these will be designed to work with a 92mm lock, or the replacement version called a Paddock lock. They will feature a cylinder with 82mm diameter on the inside and 62mm on the outside. They also come with two spindle followers. Some come with a backplate, and others are movable to accommodate different fixing centers.
Lever/Snib
Lever latches are the most basic type of door handles. Pushing down on the lever triggers a simple latch mechanism inside the door to keep it closed, which can be locked with a key. Certain lever privacy handles work using the same principle, but with the addition of the snib (like the doorknob).
A snib button can be extremely useful, particularly for homes where it's important to protect privacy or ensure security. If your partner arrives 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 type of handle is also popular for interior doors like bedrooms, where you may need to restrict access from outside.
In some instances the snib button can cause problems, particularly in the case of older locks or doors that are warped. If the snib is used in error, or by a person who isn't accustomed to it, the door may close and lock you out. You can usually get in by knocking on the door frame or the 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 smart locks can be retrofitted to double-turn pull handle kits. They are available with coverplates to hide existing holes to ensure a seamless installation. The E-LOK app is able to unlock doors using RFID cards or a mechanical key. Passcodes are also available to ensure security and convenience. The system has been tested for 200,000 times to ensure its durability. The handles themselves are constructed with a solid metal construction and are BS EN 1670:2007 Grade 5 for resistance to corrosion.
Lever/Moveable Pad
This is a well-known handle style for front doors. It comes with the advantage of keeping the door from being opened from the outside without a key if the lock is not deadlocked. This is accomplished by a 'pad' shaped external handle which locks in the gap between the handles and the lock case to stop the latch from being removed or the door from being opened.
This handle is designed to work with uPVC multipoint locks which use a split spindle mechanism. 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 modification to the existing uPVC handles but it may also require a change to the lock case or a brand new set of handle furniture to allow this additional functionality.
These aluminum levers and movable pads door handles are able for use on uPVC and feature an unmaintained slide bearing. They also include fixing lugs, spring cassettes, and an unstick slide bearing. They feature a euro-style cut out and can be installed to a variety of uPVC and timber doors.
Lever-movable pads are available in a variety of finishes to suit many different multipoint locks. They are designed to work with split spindle multipoint locks with an 92mm cylinder center and require a special split spindle set, as provided by the lock manufacturer.
