How to Identify Your uPVC Multi Point Door Lock

Posted by: Home Secure | Date: Monday, May 21, 2012

uPVC door locks are often described as multi point locks, this is because they usually have multiple locking points along the door. uPVC door locks come in hundreds of different variations but with this guide we aim to make identification a pretty straight forward process.If you want to take a little bit of the work out of identifying your uPVC door lock then please fill in our lock identification form and upload an image if you can!

Money Saving Tip!

If your uPVC door lock has failed then it may be possible to just replace the centre case, instead of purchasing a whole new door lock. The centre case is the piece in the middle of the door and this operates the rest of the lock. You can view our range of centre cases here.

Identifying Your uPVC Door Lock

The first thing to do when attempting to identify a uPVC door lock is to look for which brand the lock is. This may be stamped somewhere along the metal strip in the door. Some of the most common brands are GU Ferco, Avocet, Mila, Era, Fullex etc, you can see a full list of uPVC door lock manufacturers here.

Top Tip!

Identifying brand is important as finding a direct replacement will make the job a lot easier when installing the new lock. It is also essential if you are replacing centre case only as you will need to find an exact match to the centre case you already have.

Measuring Your Upvc Door Lock

Measurement B is taken from the centre of the key hole to the edge of the lock strip. E.G. 35mm (known as the Backset)

Replacing The uPVC Door Lock Centre Case Only – (If Possible)

If you are only replacing the centre case then you will need to identify these measurements as well as visually match your lock to the replacement. If you are not sure customers often email us a picture of their lock, stating measurements A & B.
