Work as planned
I really am pleased with the double door lock. I used them to lock up some cabinet doors and took no time at all to install. I would recommend the double door locks. I’m giving the locks a 5 star- easy to install and well made for the money. One thing that you might want to consider is shipping. I had to wait over 10 days for the locks as they were shipped by innovation ups and they sat at my local post office for 6 days before they deliver the locks

As described
I used the lock to secure an older two door cabinet my wife inherited from her parents. I had to mount it on the bottom of the doors to prevent moving the original magnetic latches. Looks great and works well.

Simple to install, works as advertised. I'd recommend this lock. Easier to install than those plastic 'childproof' things that the kids figure out anyhow!

Do I have to purchase these cabinet double door locks, keyed alike, or do I have the option to buy (3) locks keyed separately?
Randy on Jul 19, 2016
BEST ANSWER: These are only available keyed alike.
My door is 7/8 inch thick. Would this work even though it says 3/4 inch?
Travis Y on Mar 6, 2017
BEST ANSWER: Since the double lock mounts onto the enter service of one of the doors it should match with the second door and work with little or no adjustment. The only adjustment would be to the frame around the top of the door, depending on its' thickness. If it's too thick try cutting a grove for the lock tongue, too thin build it up or modify the tongue. However; seldom does anything work perfectly without a little adjusting or modification or different screws. These locks worked great for me, with very little modification of installation for a special application. These are the only ones that did work to do what they advertised to do. They are holding up well, we're satisfied with them and the price. Yes, we would purchase them again.

Do the strike plates come with the lock?

BEST ANSWER: That is what I purchased this for, and was the only thing that worked, and worked well.
Can this lock be used on cabinet doors with no center style?
Nancy G on Apr 30, 2016
BEST ANSWER: Yes, I installed it on a cabinet with no center stile, and it works well. That is exactly what the lock is made for; it is not made for doors that have a center stile. Depending on the size of the gap between the two doors, you might have to position the lock very carefully. You only get one chance to drill the hole, so precise measuring is mandatory. I made up a jig out of scrap wood to position the drill bit for the hole, and then installed the lock on some other scraps of wood just to be sure I had the position exactly right before I drilled the cabinet.
can i get three keyed alike
Lois C on Mar 7, 2016

How secure is the lock? What style of lock does it come with?
Debster on Feb 7, 2019
