Yale YDM-PRO-PVCU-35 Doormaster Professional Multi-Point Door Lock Replacement, 35 mm Backset, 16 mm Faceplate, Steel Finish, Suitable for PVCu Doors, Grey

My door latch was failing and considered getting a tradesman to repair. I thought specialist glazing tools were required to fit the parts. Glad I ordered the product now, it was easy to fit. As good as new now. It took only half an hour. If other door latch fails will order this product again. Of course you should measure your original latch fitting before ordering as there are several variations of the product. Great product.

Tired two other lock gearboxes which did not fit - screw holes not lining up within the sliding mechanism. Tried the Yale gearbox and it fitted perfectly.Definitely a quality product and door now locks and unlocks as it did 10 years ago. Very happy!

A good replacement lock. This was used to replace the broken mechanism on a set of double upcv doors, everything is working fine, but need need a decent amount of adjustment to lock correctly (not to be blamed on the lock)Initial impressions not great from the packaging - something that should probably be improved (all parts there, but barely given the damage to the box).Instructions mostly good. Worth following. If using with upc doors, you may also need to adjust the hinges themselves on the door to get a good fit. e.g. You might notice the door closes, but you can't lock the handle - the door might need moving towards the keep. I also needed to do a bit of adjustment with a saw to let the main latch go into the frame.

Used this lock unit to replace very old existing lock on front door. Took a few hours to install but satisfactory product when completed. Hope it lasts as long as the old lock. Recommend that the lock unit is installed by someone who is experienced in DIY.

A faff to fit ( 2nd time at fitting these things). Measure three times in order to fit once. Live and learn

I must have an old upvc door or something but the lock mechanism fit just fine. But no measurements specified for the size of the keeps which were too big for the upvc frame! Managed to get things working with the old ones. But wasn’t impressed.

Various options available, get the right spec and it's really very easy to install. Good quality, worked first time. Fair price.

So on opening original packaging i noted sellotape and damage to box. Suspicion aroused!Opened box and found contents as described with two pieces of additional Plastic trim (broken) I’ll come back to that. ok not losing any sleep so far. Lock mechanism fitted no problem. I’m on a roll here easy!! Next step offering keep to the door. Robin Hood would have be proud of the bow in this!!! I preserved and attempted to fit said keep on door frame. I had to carve out several sections to fit this. Job done so I thought no…. I had to remove all fittings and carve out more from the frame! Eventually after several hours i fitted this piece of …..So this was obviously used by another client! Packaging damaged, keep was bowed and a lot of PVC carving . The two pieces of plastic obviously put in by mistake by the previous purchaser on return . If you need it I have themAmazon shame on you for offering this as a new item!!
