Avocet mechanism

Last week i was called to a property in purfleet where the upvc door would not open with the handle. I arrived on site to find the latch was not retracting I opened the door checked the mechanism to find it was not in a good way.  I informed the customer,the door was still able to be locked so I locked it. I made some enquires and the mechanism needed was not available anymore and would have to fit a new mechanism and the keep as the rollers are in a different position.  I gave the owner a price he agreed to have it replaced I returned on saturday with both parts fitted them made a few adjustments to the door. The door now opens and closer properly. Happy customer happy dog.
