UHPPOTE Electric Strike Lock 12VDC for Access Control Fire Exit Door Rim Exit Devices with Push Bar

Very reasonable price… second one I’ve installed… door frame typically needs to be cut for it to fit

This electric strike mechanism works VERY well !!! I installed two on a new storage building at my business and find it to be practically flawless. Solid construction and simple installation. The only difficulty was that the size of the mechanism is a little large for the one inch width of the raised portion of the door frame. I had to cut a matching slot into the frame but this only took minutes with a portable sawzall. I'm extremely pleased with this purchase!! Don't forget to buy a 12V door access power supply (made to trigger the latch for a programmable number of seconds). I used a generic K80 door access system power supply for around $12. Nice !!!

Was working for 1 week and then just released the lock. This is a fail secure device so even if it stopped working it should just remain locked.

I installed this in a metal (steel) door frame easily, it fit great, installation was easy enough. I cut a single rectangle where the old strike was mounted on the flat steel against the corner, then mounted it and drilled and tapped a couple #10-32 screws in place to secure it. It came fail safe, I converted it to fail secure: after removing four screws to free the mechanism from the housing, then removing one screw (off center), loosening the other (centered one), sliding the loosened screw, and then inserting the removed screw in the other hole. Of course I had to solder & heat-shrink a long cable on to the wires. Then I tested it, at first I though everything was great (door locked, opened when powered, etc...).I have a "gull-wing" steel pull on the outside of my door, this allows a person to get a good two handed grip on the door. With the door securely locked I can pull it open, this is due to a couple of factors mainly the roller portion of the roller strike (I think with a normal solid strike the friction of latch against strike would not result in the frame easily flexing). If my steel frame was more rigid this would probably not happen, but this is a typical industrial steel building (8" Steel Cee Columns beside the steel door frame). Since the latch is curved (like they all are) as you pull on the door the latch pushes the door toward the hinges and latch frame away from the door. A good hard tug and presto, the cumulative flex in the steel adds up to the necessary 3/4" to pop the door open (strike still securely locked and latch too). Fortunately, I have a 1200 Lb. magnetic lock on this door, I will activate that and this will fix the problem.

Just what I needed to create a buzz in for a secure door. You can set it for either buzz in or buzz out, and have it fail locked or unlocked in case of power outage... Paired this up with a power supply and a button to complete the system...

You get what you pay for. Comparable products are about $300, and this product definitely shows why. Construction isn’t very rugged, had lots of problems with it in the first month that required constant tweaking assembley/disassembly. It works, but don’t expect much

arrived quick and works great. Seems better than other products I looked at Amazon

We just finished installing the lock, tested it out, and discovered it was working inconsistently and wouldn't open sometimes. Come to find out the deadlatch on the door put a slight amount of pressure on the mechanism, and it causes it to jam. "No problem", I thought, "I'll just take off the deadlatch or grind it down so it won't put pressure on it". Well, the bigger problem is that if someone ties to open it while unlocking it, it will get stuck then too. And to get it unstuck it's not just a matter of letting the pressure off or trying again, it gets STUCK. You have to shake it back and forth and really rattle the mechanism to unstick it, and that is just unreasonable for a newly installed device. If it was just a preload issue I could fix it, but getting stuck so badly like that is a sign that these things are too cheaply made.
