But for the price it should work ## Customer Reviews ### ⭐⭐⭐⭐⭐ A great update for older sliding locks *by on Reviewed in the United States December 22, 2019* My old double-door had the type of locks that slide up/down to move the bolt into the hole. The one at the top of the door would sometimes start to slide down thanks to gravity, whenever the main door would open/close and vibrate. I found myself constantly checking it to make sure it stayed locked.I bought these since they had the same apparent dimensions as the old ones and figured it'd be a pretty quick replacement. Of course, upon removing the old locks, I realized they didn't route out the entire area in the side of the door. The old ones, in other words, were kind of cheap and not solid blocks.So I had to spend a little time chiseling out the pocket to install these. These are wonderful updates, but just be prepared to do a little work if you're updating an older door. A sharp set of chisels and maybe a multi-max tool for speeding things along. I also had to slightly widen the existing holes in the top/bottom of the door frame since the alignment of the bolt wasn't quite the same, but at least that was easier to accomplish.In the end, I know have these great lever bolts and I don't have to worry about them working themselves open on their own, and more secure since you can't bypass them with a wire or something from the outside. You can only open/close them when the main door is open. They're also so much more solid feeling than the old set. The bolt seems higher quality, and having a full, solid body embedded in the door makes me think it'd hold up better if someone tried to kick it in. ### ⭐⭐⭐⭐⭐ Very Good Quality Product *by on Reviewed in the United States December 9, 2025* The bolts themselves were good quality, it just took a lot of effort to get them to fit in the spot needed (door's fault, not the product). I measured what I needed and this was the closest to the fit that I could find.If anyone is planning on replacing your flush bolts, get the closest size to fit you can find and plan on a lot of grinding to make it fit. In the end, they work well and look good.Even with the extra work, it was still better than spending hundreds of $$$ on replacing the Astragal. ### ⭐⭐⭐⭐ Great replacement *by on Reviewed in the United States July 16, 2022* 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. ## Frequently Bought Together - 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 - JQK Closet Door Ball Catch Hardware, Stainless Steel Catch Adjustable with Strike Plate, Brushed Satin Finish 2 Pack, HBC100-P2 - Ceoighe 2 Pack Flush Bolt for Double Door, 7 Inch Heavy Duty Chrome Plating Flush Latch Bolts, French Door Lock for Inactive Leaf, Double Door Opening and Composite Wood Double Dummy Door --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/50952204-sumnacon-2-pcs-door-flush-bolts-6-inch-flush-bolt](https://www.desertcart.gr/products/50952204-sumnacon-2-pcs-door-flush-bolts-6-inch-flush-bolt) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-10-25*
