Review: Very Good Quality Product - 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. Review: These are brilliant!!! - 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. ## Features - Flush bolt be used to secure the opening for composite door,French, patio, wood, double or other doors.This great small device features automatic holding spring to provide tension for both retracted and projected positions.It often be installed on inactive leaf of double door opening (top and bottom) to offer safety function. - Our flush bolts are all machined from solid stainless steel for anti corrosive and rustproof,heavy duty and sturdy.

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.

Highly recommend. ### ⭐⭐⭐⭐⭐ Better than other(s) *by G***G on September 4, 2025* 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). ## 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.com.ar/products/50952204-sumnacon-2-pcs-door-flush-bolts-6-inch-concealed-security](https://www.desertcart.com.ar/products/50952204-sumnacon-2-pcs-door-flush-bolts-6-inch-concealed-security) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-22*
