Types of UPVC Door Handles It is essential to select the right replacement upvc handle for your home if handles made of upvc require replacement A locksmith can offer and install highsecurity uPVC door handles with extra security features The most important measurements to consider are the measurement A also known as PZ as well as the length of the backplate Check these measurements to ensure that your new uPVC handle will fit LeverLever A lever is a rigid rod that pivots around the point When you apply force to the end of the bar the fulcrum will turn in the direction the force is applied This rotates the force and allows you to lift or move things that normally require more force to lift The distance between the fulcrum of the lever and the point at which you apply force determines the most effective movement This is referred to as the mechanical advantage The advantage in mechanical terms increases as the lever gets extended You can calculate the mechanical advantage by dividing distance from fulcrum point to the place where you are applying force by the distance between fulcrum point and the end of lever Levers can produce different effects depending on the way the force is applied For example a lever of class 2 is inclined to turn in the opposite direction to when the force of effort is applied like a Ttotter If you push the handle of a door the forces will produce the same rotational effects as this However levers dont create energy Levers increase the force by changing small amounts of effort applied over a lengthy distance into greater amounts of force that are applied over shorter distances Levers are used to lift heavy objects and transport massive amounts of cargo This is also the principle behind the levers that are found in many everyday tools such as crowbars fishing rods claws for hammers and even your own legs when you stand on the hand brake of your vehicle LeverPad Lever pad handles are a form of door handle made from UPVC with levers on both sides to operate the multipoint lock These are available in various finishes and designs and can be used on a wide range of materials such as UPVC doors Aluminium doors Timber Doors They are sold in pairs for both the outside and the interior doors with screws and spindles included They are also available in handed and unhandled versions to suit different types of users They are typically used for new constructions and are installed to replace doors made of upvc They are typically operated by lifting the levers which throw out all of the multipoint locks and turning the key to close and unlock They provide additional security when compared to traditional lever door handles since the locking mechanism can only be gained via the inside using a key in the event that the door is locked Theyre not as secure as a cylinder lock however they are an affordable way to add extra security to your home The only disadvantage is that they dont offer the same level of protection like a cylinder bolt and consequently dont block access to outside if the door has been left open We stock a large number of lever pad upvc handles manufactured by leading manufacturers in the industry They are made from highquality components In general they are supplied with a manufacturers warranty Typically they are designed to be compatible with a 92mm lock or the replacement version known as a Paddock lock They will have an 82mm cylinder center on the inside and 62mm on the outside They also come with two spindle followers Some come with the backplate in place while others are movable to accommodate different fixing centers LeverSnib Lever latches the simplest of door handles are utilized Pressing down on the lever operates a simple latch mechanism inside to keep the door closed It can also be locked with the use of a key The levers for privacy are based on this same principle however with the addition of an snib like the doorknob A snibbutton can be very beneficial especially for homes where its important to ensure privacy or security If your partner arrives at home late from work you can use the snib so that they wont be able to enter until theyre ready to move in This kind of handle is also popular for interior doors like bedrooms where you might need to restrict access from the outside In certain situations there are instances where snib buttons could cause problems particularly if you have older locks and doors that are distorted If the snib is used in a mistake or by a person who isnt quite used to it the door could close and shut you out It is possible to gain entry by knocking the door frame or letterbox However this is not ideal If your uPVC door has a snib button We recommend replacing the handle with an modern ELOK 7Series smart lock

used to open doors using RFID cards or a mechanical key Passcodes are also offered for security and convenience The system is tested to 200000 cycles to ensure longterm durability The handles are made from solid metal and meet BS EN 1670 Grade 5 for corrosion resistance LeverMoveable Pad This is a popular handle style for front doors It has the benefit of stopping the door from opening by the outside without keys if the lock is not deadlocked This is achieved by an external pad handle that locks in the gap between the handles and lock case to stop the latch from being pulled back or the door opened This handle is designed to work with uPVC multipoint locks which use a split spindle mechanism This type of operation requires that the lever handle and the external pad handle are both fitted to the same lock case This could be a straightforward switch from the current uPVC handles but it might also involve changing the lock case or even a new set of handles to accommodate this
