Pack of 5 x Adjustable Tubular Latch 60 to 70mm Mortice Latch, Door Latch

works really well. Good value for money

These do 60 and 70mm, with 90 degree rotation, making them suitable for knob, but not for handles ( which need unlocking with 45 degree rotation). Quality seems similar to big DIY chains' own brand. Cheap enough to want to keep them rather than scrambling for some later.

This product was exactly what we needed and it got us out of a hole as the length of catch’s we needed aren’t manufactured anymore.

I bought 2 boxes over 3/4 broken

Good quality latch for Wiseman handles with either a 60mm or 70mm backset position. These are not so common as they used to be but these are a good replacement. Would recommend this supplier.

Needed the adjustability of these to match my existing locks. 2 of mine failed (20+ years use) these replaced them perfectly. Using them with round knob handles ad are very ease to operate.

Easy to install yes, value for money, not bad, but sturdiness? I rated this as 1 star because these are so loose and sloppy, they are not at all suitable for door handles, not even my high quality sprung handles. Door knobs, yes. The spindle socket requires a 90° or more turn to retract the latch enough to open a door and has 30° of looseness before it even actuates. I tried two in case one was faulty but both the same so I’m afraid these are going back. I would not recommend these for door handles of any sort.

The latch on the biometric lock for my study jammed and I thought I'd have to buy a new lock (and maybe door....). Saw these on Amazon - I only needed one but they came in a pack of 5. They are identical to the one that jammed so it was really easy to fit. I now have 4 spare in case the current one jams!
