UPVC Replacement Door HandlesOver time the handles on your doors will wear down and need to be changed. It is crucial to match the dimensions of the handles that were previously used when replacing them.The top screw’s location, the lever and the keyhole dimensions are the three measurements you have to check. Use the size guide to help you.Inline Lever/LeverA lever handle is a contemporary door handle designed to suit new or replacement doors. This style door handle is offered in a variety of styles & finishes. A number of manufacturers offer this handle including Avocet, ERA, Fullex, Hoppe, Mila, Millenco & Yale.Fab and Fix Windsor Inline Sprung Lever Door HandleThe door handles made of uPVC/Composite are constructed of durable materials and are ideal for multi-point lock doors which require a robust design. The handles are inline and use the same screws and spindle to fix them. They can be easily mounted on a new or existing uPVC/Composite doors.The handle can be positioned and angled to suit any user. The handle has been tested for endurance up to 200,000 cycles, which helps to ensure the quality of the finish and the performance of the handle over time. The sprung lever can also be reduced to accommodate the widest range of locks. This is particularly useful in doors that are narrower, where the cylinder is further back from the door. A shortened lever is also an excellent option for doors that have latches that can be opened by a thumb turn inside.Lever PadA Lever Pad door handle made of upvc functions differently from lever-type handles found on most doors. These handles can work off one single spindle (inline) or independently from both sides using two offset or inline spindles (pad). They are generally employed on UPVC double glazed doors and come in many variations & finishes.The handles have been tested to the minimum of 200k cycles and are available in a variety of finishes, including White and Silver, as well as Chrome & Gold. The finish meets BS EN 1670:2007 Grade 5 and is also resistant to corrosion, thereby giving the handle a high degree of durability and performance for the intended use.All of the UPVC handle lever pad styles come with a spindle and screws that allow them to be installed on a new or existing uPVC door. The 211mm backplate fixation centres permit a larger handle, which is typically an advantage when replacing a damaged or old multi-point door lock mechanism. These handle levers have springs, which eliminate the issue of door handles that sag out of horizontal position when they are not being used.It is crucial to match the PZ dimensions for both the multipoint lock as well as the uPVC doors when choosing the replacement UPVC spindle and handle. This measurement can also be called ‘handle centres’ or cylinder centres’. It is important to match the right handles.After you have determined the proper PZ size and the correct PZ size, you must make sure that the lever and push pads are shaped to match the American with Disabilities Act compliant handles that you need for your door. They are usually of a round or square shape with an internal lever and external push pad.Most of the UPVC lever pads that we offer are sprung, which means that they return to their horizontal position when they are not being used, instead of hanging out and possibly securing in the frame. This stops draughts from entering the property. The majority of UPVC lever pad handles are available in left and right handed versions which allows them to be put on either side of doors.Euro CylinderCylinder locks are usually used on uPVC doors, but they can also be used on other types of doors. The cylinder lock operates with a key that unlocks the cylinder’s casing. This reveals pins that can be aligned with the pins in the lock, and permit them to rotate the camera that rotates, opening the door. Euro Cylinders are available with up to six pins. External and internal doors require different levels of security.The choice of cylinder is vital. It’s dependent on the use that your doors and handles receive. For instance, doors that are external require a more secure cylinder whilst internal doors can be secured with an ordinary cylinder. Certain cylinders come with extra features that can improve security, such as anti-drill or anti-bump properties.A euro cylinder needs to be measured accurately to ensure it is the correct size for your door. The cylinder must be measured from the central screw hole to the ends of the cylinder. This includes the thumb turn, in the event that one is present. If you are unable to measure using the lock in its position, you can take it out of it. It is crucial to not have a cylindrical lock that extends beyond the handle or escutcheon. This can make it vulnerable to snapping lock attacks.The design of most newer cylinders comes with anti-drilling as well as bump resistance features. These are designed to reduce attack chances by forcing the cylinders to rotate in a different direction. This can help deflect the attack, and ensure your door is secure.There are cylinders that have been constructed to withstand snapping. This is a common occurrence on cylinders. A specially designed tool is used to break the lock’s break line and then the front of the cylinder is snapped off. This is much quicker and less difficult than gaining access through multipoint locks and leaves no evidence of a break-in which can hinder an insurance claim.Spring CassetteThis spring cassette is found inside the base plate of the door handle. It offers a spring-loaded solution to return your multipoint lock handles to their normal position after use. The handles were previously equipped with no spring and would droop when the locking mechanism was disengaged. This simple part is the best solution to fix this problem. It also prevents your door from becoming stuck in either the closed or open position, as they are difficult to close manually.These spring cassettes are specially made for use with multipoint locks that are sprung but they won’t work with multipoint handles that are not sprung and you must have a custom hole cut into your backplate in order for them to fit (please look at the image for a technical diagram). These cassettes are a replacement for damaged or missing cassettes in the backplate of uPVC door handles . They are fitted with an elongated square that accommodates an 8mm spindle and they are supplied individually.These spring cassettes are an excellent value solution to the problem of door handles that have become sagging. They are simple to install and will increase the lifespan of your uPVC door. Please contact our team for more information on our range of uPVC accessories and spares.
