Prime-Line E 2199 Stainless Steel Mortise Lock - Adjustable, Spring-Loaded Hook Latch for Sliding Patio Doors Made of Wood, Aluminum & Vinyl, 3-11/16”, 45 Degree Keyway, Round Face (Single Pack)

Works great. Good product. Would recommend to others.

Just what I needed 👍

After buying the handle kit with latch and having the latch break within a little over a year I decided to buy a latch separately and it aligned so much better than the other and it locks perfectly.

The latch on my back door had a spring to break inside, so I needed a new latch to replace it with. This was overall easy to install. I had to buy it twice because the first time I dropped it immediately into the inside of my door frame (it’s still sitting there to this day). The second time, I had a very strong magnet attached to it and it installed seamlessly. It fit with the handle and lock I already had without issue. I gave it 4 stars only because after having it for about 2 months or so, I’ve noticed that the lock latch piece doesn’t seem to open all the way when I move the lock handle - it needs a little extra push that it didn’t need after I first installed it. It doesn’t prevent the door from unlocking or locking fully. I just try to be mindful of it and push the handle farther to make sure the latch is fully unlocked so I don’t damage it. Other than that, it was easy to install and works well. I would purchase again!

I was amazed that this is a universal part and so easily available. Worked like a champ and save me having to call a pro to fix a sliding door.

Perfect fit great product

Worked as advertised and 1/2 the cost of Lowe’s. 3 years later and it has broken and another ordered.

So my old mechanism had broken the return spring for the lock mech and when I went to unbolt and remove the assembly it fell to the bottom of my door. With no way to retrieve it I had no lock on my door. Ordered this hoping it would fit and low and behold it did. The hardest part of the install was holding the part in place to bolt it in. Once bolted in, the lock worked and all looked as if nothing happened. Overall would recommend for someone who knows what theyre doing and has the knowledge to remove and install. Or if you have a screwdriver and can turn it left and right, you should be good

Fits perfectly for my patio door. Easy to install. Fixed my broken patio door lock in less than 30 minutes.

Was a identical replacement for my existing door. Installed in minutes. Worked as I would expect.

Front sliding door.

So far works good. Time will tell

My sliding door latch failed. I ordered this one, it arrived the next day and it took five minutes to install. End of review. Easy.
