A Brief History Of The Evolution Of Upvc Door Handles
Types of UPVC Door Handles

It is crucial to select the appropriate replacement handle made of upvc for your home when your handles made of upvc require replacement. Locksmiths can supply and install high-security uPVC door handles that come with additional security features.

The most important measurements you should take are the measurement A (also known as PZ) along with the length of the backplate. Check these measurements to ensure the new uPVC handle will fit.

Lever/Lever

A lever is a rigid rod that pivots around the point. When you apply a force at the end of the lever it is likely to cause it to turn 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 tried to apply it directly to the load.

The distance between the fulcrum and the point where you apply the force determines the distance the lever can be moved. This is called the mechanical advantage. The more the lever extends, the larger the mechanical benefit. You can calculate mechanical advantage by dividing distance from the fulcrum point to the point you are applying force by distance between the fulcrum point and end of the lever.

Levers can have a variety of effects depending on the way forces are applied. For instance a lever of class 2 has a tendency to turn in the opposite direction when the force of effort is applied (like a teeter-totter). The forces generated by pushing the handle of a front door will create rotational effects similar to those.

However, levers don't create energy. Levers multiply the force by changing small amounts of effort applied over a long distance into larger amounts of force applied over smaller distances. Levers are used to lift heavy objects and move huge amounts of cargo. This is also the reason behind the levers that are found in many everyday tools, such as crowbars, fishing rods, hammer claws and even your own legs when you stand on the hand brake of your car.

Lever/Pad

Lever pad handles, also known as upvc door handles, have levers on each side to operate the multipoint locks. These are available in various finishes and designs and can be used on a variety of materials that include UPVC doors, Aluminium doors & Timber Doors. They are sold in pairs for the doors, both exterior and interior, with spindles and screws included. They are also available in hand and unhanded versions for different users.

These locks can be used to replace an existing doors made of upvc. The levers are raised to open the multipoint locks, and the key is turned to lock or close the door. They are more secure in comparison to lever handles for doors as the locking operation can only be gained via the inside using keys unless the door is locked.

They are not as secure as a cylinder bolt, but are a cost-effective alternative to add security. The only disadvantage is that they do not provide the same level of security like a cylinder lock and therefore don't block access to your home if the door is left open.

The majority of the lever pad upvc door handles that we stock are made by the industry's leading manufacturers and therefore are made from high quality components. They are also generally supplied with a manufacturer's guarantee.

Typically, they will be designed to be compatible with a 92mm lock, or the replacement version of this known as a Paddock lock. They will feature an 82mm cylinder centre on the inside, and 62mm on the outside. They are also fitted with two spindle followers. Some are inserted into the back plate while others are movable to enable different fixing centres.

Lever/Snib

Lever latches are the simplest kind of door handles. The lever is pushed downwards to operate a simple latch inside the door that can be locked with keys. Certain lever privacy handles work based on this same principle, but with the addition of an Snib (like knobs for doors).

A snib button can be extremely useful, particularly in homes where it's essential to protect privacy or ensure security. You can use the snib feature to prevent your partner from entering until they are prepared. This type of handle can also be put in on doors inside, such as those in bedrooms where you wish to limit access from outside.

In certain situations the snib button can cause problems, especially when you have older locks and doors that are warped. If the snib switch is accidentally pressed or by someone who isn't familiar with it, your door may be slammed and you locked out. You can usually gain entry by knocking the door frame or the letterbox. But this isn't a good idea.

If your uPVC has an snib, we suggest replacing it with an electronic lock from the E-LOK 7 Series. These smart locks can be retrofitted onto double turn pull handle kits. They are available with coverplates to hide existing holes to ensure an easy installation. The E-LOK app can be used to open doors using RFID cards or a mechanical keys. Passcodes are also available to ensure security and convenience. The system has been tested for 200,000 times to ensure long-lasting durability. The handles are constructed of solid metal and meet BS EN 1670 Grade 5 for resistance to corrosion.

Lever/Moveable Pad

This is a very popular handle design for front doors. It has the benefit of stopping the door from opening from outside without keys if the lock isn't deadlocked. This is accomplished by using an external handle that is shaped like a pad that locks into the gap between the handle and the lock case.

This handle is designed to work with uPVC multipoint locks that employ split spindle mechanisms. This kind of operation requires the lever handle as well as the external pad handle to be installed on the same lock case. This can be a simple modification to the existing uPVC handles but it may also require changing the lock case or a brand new set of handle furniture to allow for this additional function.

These aluminum levers and movable pad handles are suitable for uPVC doors and feature a maintenance free slide bearing fixing lugs, spring cassettes, and fixing lugs provided. They feature a euro-style cut out and can be fitted to a wide range of uPVC and timber doors.

The lever-movable pad is available in a variety of designs to fit a broad range of multipoint locks. They are specifically designed to be used with split spindle locks that have a centre cylinder of 92mm and require a separate set of split spindles supplied by the manufacturer of the lock.

These Hoppe London 77G/3831N/113 lever moveable pad handles are made of cast aluminium with an anodised surface that is resistant to corrosion and has high scratch resistance. These handles can be used in combination with a variety of other Hoppe products, including patio door handles. french door handles, and window handles for windows. They also have an escutcheon for security.

Lever/Moveable Snib

The lever handles are one of the most commonly used types of upvc doors handles. They are available in a variety of designs. It consists of two handles that can be locked and moved by a thumbturn cylinder, or the use of a key. A pad handle can be used as an alternative to lever handles. It is comprised of one that is fixed or moveable which can be used to operate locks. These Fullex handles feature a spring lever pad and a snib which can be turned on to ensure the latch is held.

When choosing a replacement upvc handle, you need to consider the screw centres, the back plate length, and the PZ measurement. This will ensure that the handle will work with your current locking system. You can use our online measuring guide to assist you in taking these measurements, so you're certain that the new handles will be the perfect fit.
