Sumnacon 2 Pcs Door Flush Bolts - 6 Inch Concealed Security Door Locks for French Doors,Composite Doors,Wood Doors,Double Doors,Dummy Doors,Brush Stainless Steel Finish

Used these to replace some slide up locks that kept sliding down. Problem fixed, install was easy and they work great

Received this product a while back and they looked good. Finally got it install them and the bolt action was perfect and also tested the holding strength to a point. They held up well and the pin did not bend.

Once installed, these function very well, look good, and are really sturdy. Obviously cutting the mortise in your door takes a steady hand and a tool appropriate for the job. I cut into pocket doors without dismounting them, which makes the operation a little more difficult. If I recall, these ended up kind of pressure fitting into the mortise and then secured with a couple screws. The floor plate is also best recessed and looks really good when fit well.

We have a set of french doors that we purchased 20 years ago from habitat for 50 dollars. They are solid wood with glass with louvers inside the glass. The outside is clad in heavy anodized aluminum. For security and weather proofing. They were custom doors that still had a 1000 dollar retail sticker on them. A friend of mine who a few years later passed away from cancer created a frame and help install them on our house. I still think of him every time I use those doors.Anyway the old latches that these replaced were I think a mixed bit of better and worse quality. They were heavier cast metal than these are but with a smaller diameter post that was one piece for the length of the slide mechanism. The older cast metal I think was a bit more brittle than these but these are a bit more light weight stamped stainless frames.Design wise I like these better as the mechanism is much easier to use and never be able to accidentally come open on the top due to gravity as I have heard other people complain about with my original design with lesser quality latches than we had. These were about 1 inch shorter than our old latches but were a perfect fit for width and depth. I had to use a rubber mallet to gently tap them into the original channels with out having to make any modifications. The post being a larger diameter, I had to drill out the post holes in the frame of door top and bottom to the new diameter. For me this worked out well as I was able to get a snugger fit than we originally had, leading to less play in the door when latched.I would purchase these again.

Mortised the door to accept them, and they look great. Obvious door modification is required if no existing mortise pockets, but once installed, the door feels strong, the bolts are long enough to not need to raise the threshold, it looks clean and it feels very secure.Respectfully,Nathan Evans

I have 2 pairs of 10-14 year old French doors on the back of the home I just purchased. The cheap friction based plastic slides had cracked/failed and otherwise looked like they were on their last leg from years of brutal Florida sun and the pins were rusting from the salt air. These stainless steel assemblies effectively were direct replacements although they install differently then the originals. The originals that were still intact required the dooe be removed to get them to slide out, otherwise they stopped at the floor. These go in from the side and can be installed with the door in situ.The units were ever so slightly thicker and were sitting a little proud of the door frame. A little sanding/tweaking was needed on the tighter door set. The other set fit just fine. I needed to drill larger pin holes as these are a bigger diameter. Once installed, they look great, work even better and was so glad they were dimensionally near perfect in most respects. 2 mm less deep and I wouldn't have had one issue. Highly recommend.

I remember this type of hardware from years ago in a rental unit we had. It was hard to find these anywhere. I always love it when I can find something on Amazon that is no longer commonly available, and at a great price.

The media could not be loaded. I bought this to keep one of my double doors in place. It did do the job, but 1 of them came off track when I was trying to latch into the frame. The other one worked exactly as expected, after I found the proper placements using the first one. I’m using it for an interior door. Not quite sure if I would use it for an exterior door. Feels pretty sturdy for my interior door.
