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

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.

My use case: Front double door, normally closed half, top & bottom.Prior device was notched into door, very flimsy, expected to be one finger pushed up/down. This control, flip out and across, is much less prone to getting stuck in place.The thickness of the metal parts is about the same. Not too flimsy, not Swiss strong.5 for ease of installation, decent price, looks nice. Shorter by 30% of the device that was there before, used wood filler to backfill the gap. The prior one was probalby not cheap and this was a screw in replacement.Screws were shorter by half with this vs old (easier screw-in, probably not as strong).

One of the flush bolts we received the sheet metal was not bent correctly, but a pair of pliers fixed that issue before we installed them. The functionality is solid and have not had any difficulty operating the flush bolt. Very happy with my purchase.

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.

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.

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.

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.
