Prime-Line E 2014 Mortise Lock - Adjustable, Spring-Loaded Hook Latch Projection for Sliding Patio Doors Constructed of Wood, Aluminum and Vinyl, 3-11/16 In., 45º Keyway, Round Face (Single Pack)

Hey! My mother in laws door works again. This lock looks, fits, and functions exactly as it should, albeit with a bit stiffer motion. Now that they can lock the door when out of the house, things are a bit more secure. Its very easy to install...unless you drop it down inside the door. I mean, that may have happened. If it DOES fall inside, that adds a couple more steps. Frist, remove the inside and outside door handles. Take out the two screws that hold the lock in place, then slide it out. On new one, extend the locking latch to give you something to hold. Fish it back inside the opening, line up the holes, and reinstall the two screws, put the handles back on. That's it. If you DID let it fall inside the door, you need to take the whole door off the track. On the bottom of each side, there are two screws. The bottom one adjusts the height of the wheels that roll on the track, while the top locks in that adjustment. To take off the door, loosen the top screw, then adjust the bottom screw all the way down, repeat on the other side. Lift up on the door, pulling the whole thing up and off the track, then stand it up on its side, handle side up. You'll need to take out the track slider on the latch side by removing those two screws. We used a straightened metal clothes hanger to push the latch back to where it should be, then used the hook end of the hanger to lift it enough to screw it in place. Put the handle and slider back on. To get the door back on, slip the top of the door into the top of the channel, then lift from the sides to get the slider wheels on the proper track. You'll need to adjust the height and square of the door again by means of the bottom screw. This has to be raised evenly or the door will not be square, meaning if you make 5 full turns on the left side, you'll need to make 5 full turns on the right. If the height isn't right, the door wont roll easily and the latch will not slide into the frame opening. One you get the height set, tighten the top screw to lock each side in place. Do you see how much easier it would have been if you (I) had just held on to the latch while putting it on? 5 minute fix turned into a half hour. Hindsight. Good times.

While replacing a lock set on my niece's sliding glass patio door I pulled the actual "lock" out of the door for inspection and cleaning. The original door handle literally failed by fracturing at the base of the handle and folding completely back on itself. Upon inspection the "lock" portion of the lock set was found to be in very good condition and did not need replacing, so why did I order this lock? The slider on my niece's home has a vinyl frame, and that frame is hollow so the lock, while being a "mortise" type did not fit into a mortise pocket; rather, it fits into the "hollow" of the frame and is held in place by the two screws of the handles (inner and outer). Unfortunately, as I was attempting to re-insert the lock into the mortise opening and fit the handle and screws in place, the lock slipped down and actually fell all the way to the bottom of the internal hollow of the door. Despite being only about 30 inches or so below the mortise opening and trying every idea I could think of to retrieve it, that lock was no longer available to be put back into use. It was gone for good! Fortunately for us there are a number of sources that can supply replacements. We ordered a new one from Prime-Line through Amazon. The price was very good, and the lock itself is an exact duplicate of the door's original lock (except for some stamped numbers that the original manufacturer had placed on it). It fit the new replacement lock set handle that we had picked out (also from Prime-Line) perfectly and it works great. I did need to file down the door's mortise opening on one side just a bit, but this is a normal thing as parts produced years-apart are always going to have some minor differences in how they fit. This was an excellent choice to use in finishing my niece's door "upgrade!"

My original patio sliding door lock broke, including the latch used to operate it. I didn’t have the model number for the existing lock, so I took a chance on this replacement after doing some rough measurements — and it mostly paid off. Removing the old lock was tricky (I lost it inside the door after removing the handles), but once I got access, I found that this mortise lock was a close match. The included instructions weren’t very clear, and I ended up needing to file down the mortise slightly to get it to fit properly. That said, once installed, the lock fits snugly and works well. It is a bit stiff when engaging the latch, but I plan to apply some lubricant and expect that will help. Overall, a solid product, especially for the price — just be prepared to do a little adjusting depending on your door setup.

Easy to install on our sliding glass door. Lock moves easily and is good quality.

Fit Perfect super easy install and lock works perfectly and only now I understand how much of a difference a good locking mechanism makes ! 10 out of 10

Item fit okay, installed easily and looks good. The new latch seems uncomfortably stiff to actuate compared to the old one before it went bad. I've set the adjustment screw for optimal reach and movement, but that appears to have no affect on the stiffness of the latch lever. Maybe that's normal for a new latch. I'll see how it goes. An install tip for the DIY, I used a pair of needle-nose vice-grips to prevent accidentally dropping the latch into the door frame before I could get the first screw set. Also used the vice-grips for removing the old one for same reason.

Works great in my old sliding glass door but.. BEWARE! Don't be like me.. read the instructions.. engage the lock prior to installing, otherwise you may or may not accidentally drop this latch down the inside of the door frame where you can't reach it and then ultimately need to order a second latch..

Worked good Easy to install

Quedó perfecto no pensé que lo fuera a encontrar creí que tenía que comprar todos la chapa gracias

J'ai opté pour le modèle standard et très heureux de constater que la mise en place fut facile et rapide. Le produit est de bonne qualité, suite a son installation j'ai vaporiser un peu de W40 dans la cerrure pour un fonctionnement plus fluid.e

Excellent product - as described - easy to install - add a little lubricant and works perfectly. Took more time to figure out what to order than installation!

Please see above

3 minutes to install, works perfectly. Couple bucks cheaper than the Big Box Stores and delivered free so that's a bonus too.
