2 Pack 6 Inch (150MM) 304 Stainless Steel Security Door Fireproof Composite Door Guard Bolt Latch Slide Bolt Lock

We have a 2-part commercial door (3-foot active door and 4-foot inactive door with internal flush bolts that release when active door is open. The internal mechanism on the inactive door failed, and a local commercial door repair company quoted me $800 for a new internal mechanism including installation. I found this well-made, reasonably-priced product in 304 stainless on Amazon that came in pairs, so I installed one each on the interior top, and interior bottom, of my inactive door. My inactive door is "rock-solid closed" when the latches are extended, and easy to open by flipping the levers to retract the bolts. I have $790 more in my pocket than if I'd hired the door company and the latches are functional, affordable, and nice to look at. Very happy.

I used these on a double door I made for a shed. In order to have a functioning doorknob I needed to make sure that the other, non-knob door stayed fixed closed. I had looked a different hardware that is mounted to the inside of the non-knob door, but it all looked bulky and like it would get in the way. These get mortised into the edge of the door and include a spring that positively open or closes them - no chance of them falling into the wrong position. They are completely stainless steel and nice, thick construction. I was really happy with how they install and operate. This is a great value & I highly recommend them!

Quality product for the price. Easy to install and improves overall standard French door locks.

I like the that they are very compact. I used them onmy french doors.

Too Small for my Opening , I Need to Return, I need a Return Label.. Thanks

Quality Works great

great product

Easy to install, easy to operate.Comes with short screws that do the job, but depending on the door you mount it on, longer screws would add strength.
