There are a number of indicators to help identify your multi-point door lock. The first clue may be the manufacturers name or mark located on the lock faceplate, for example, the ‘GU’ brand logo is marked on all of their locks. There are two critical lock case dimensions that are required when identifying a lock, these are known as the PZ dimension and the backset dimension. Using the technical drawing on page 4 of the Eurocell door & window hardware catalogue as a guide, the PZ dimension is measured from the centre of the spindle (follower) hole to the centre of the top diameter of the lock cylinder (barrel) hole. (If there are 2 spindles always measure from the top spindle hole). The Backset dimension is measured from the front of the lock faceplate to the centre of the spindle (follower) hole. Based on these two dimensions we can begin to narrow down the identification process. Other key features include the type of centre case e.g. latch & dead bolt, the type of follower e.g. single, split or dual, how many lock points e.g. 4 rollers and the lock case positions. We always advise customers to view the UPVC Door Lock identifaction page which provides a comprehensive solution.
2. How do I identify my door handle?
Similar to the process of identifying a multi-point lock, there are a number of key indicators required. The door handle identification page is an essential tool to help. There are two critical dimensions required when measuring your door handle, these are the PZ dimension and screw to screw dimension also known as the fixing centres. The PZ dimension is measured from the centre of the spindle (follower) hole to the centre of the euro cylinder hole. The screw to screw dimension is measured from the centre of the top fixing screw hole to the centre of the bottom fixing screw hole. You will also need to note if the handle is lever / lever or lever / pad operation.
3. I need a replacement euro cylinder barrel, which size will fit?
There are two dimensions required when measuring a euro cylinder. Measurement A is measured from one end of the cylinder body to the centre of the screw fixing hole. Measurement B is measured from the centre of the screw fixing hole to the other end of the cylinder body. This will provide you with a measurement of the size you require such as 45mm/55mm. If you require a thumb turn cylinder, measurement A must always be the internal facing side. Furthermore, it’s essential with certain anti-snap euro cylinders to fit the product so that the snap line is externally facing.
4. How do I measure my window friction hinge?
Using the friction hinge measuring guide, there are 3 simple steps to follow. Step 1 hang type – is your window top hung or side hung? Step 2 hinge length – measured to the closest inch. Step 3 stack height – either 13mm or 17mm. If followed correctly you will be able to identify your replacement friction hinges (sold in pairs) for example, top hung 10” friction hinge with 13mm stack. If you are unable to measure the stack height of the hinge then you can purchase some stack packer caps. The caps simply clip on to the hinge and convert the hinge from a 13mm stack to a 17mm stack. We recommend fitting 3 packers per hinge (so a pair of hinges would require 6 packer caps).
5. I need a replacement window handle, which type and what size do I require?
There are 4 main types of window handle - Espagnolette, Cockspur, Blade/Fork and Tilt & Turn. Espagnolette handles are the most common type found on newer PVC-u windows and are used to operate espagnolette window locks. When removed from the window, espag handles have a spindle bar protruding from back of the handle. Please measure from the end of the spindle to the body of the handle to identify the spindle size you require, e.g 30mm. If you are unsure which spindle length you require, we offer a repair handle kit with 5 spindle lengths to cover all applications. Cockspur window handles are commonly found in older PVC-u installations and are either left hand or right handle specific. They can be differentiated from espag window handles by the noticeable spur that protrudes to the left or right of the handle near to the push in button. Cockspurs do not feature a spindle bar. The Schlosser Technik Apto Cockspur Handle is a one size fits all repair solution covering cockspur applications from 9mm to 21mm. Blade / Fork handles are less common and more likely to be found in commercial properties. They feature a blade or fork style mechanism protruding from the back of the handle. Tilt & Turn handles are specifically for windows that open inwards and tilt downward. For more information identifying your window handle, please see the Window Handle Identification page on the Eurocell Hardware website.
