My door and the supporting hinge are not on a level plane - will this item work with a slight space between the magnetic parts (without alarm trigger?

It works for me. As long as you don't exceed about half an inch between the two planes of the alarm, you should be good. I used stacked double-side tape to bring the two alarm pieces to closer alignment and have had zero issues (have used these alarms in two houses over the course of the last five years)

Glue a small piece of foam or rubber under the lower part to make them both on the same level.

It will still work fine. In fact, you will only need to attach the sensor side since the magnet will cause it to stick to the door. Since the alarm only goes off when the door if open there will be minimal interference so long as you do not place the receiver directly behind where now open door is between the transmitter and receiver since the signal will now have to bounce around before being received.

I have my sliding screen door butted up against it and it would fine. You might have to adjust your screen door abit, to make sure that it lines up correctly.

So long as it is a standard 2 wire recessed magnetic contact switch, it will work. You may have to enlarge the openings for each stub, as I did, but it doesn't take long. It was worth the effort, very strong magnet to ensure switch closure even with a door that may have a large gap.

Sure will , they are simple magnetic contacts, a metal door or window wont effect them at all.

It will work OK if the door track isn't too high (probably needs to be under 1 inch). Of course, you won't be able to close the door with the safety bar in place.

The bottom of my door is 1" above top of the base plate. The base plate is 1/2" in height. Ideally, you want the bottom of the door as close to the top of the base plate as possible to give it the most resistance strength. You could add another flat piece of steel or aluminum to sandwich between the floor and base plate to raise it up. But I think it will work for you.

It should. however, like the previous reply noted, it will easily fall off with minimal weight. I drilled four holes in my safe door (Stack-on pot metal) and bolted the organizer on. The four bolts were two in the upper corners, and two more about half way down. that way the fabric can stretch as needed. Its great for the price. The best thing, however, is the motion sensor lighting. It too fell off so I use high-power magnets to hold it on. open the door and it fills with light. i thought it was more of a gimmick at first, but would never go without it now.

if your door does not stick when u shut it, this will work, its very very thin. I love mine

Sorry I can't really say except I do think would be a hindrance as it connects the slider to the stationary door quite firmly and we feel pretty secure with it. Do be sure to push the bar into its holder if YOU go outside as I've had the experience of not doing that and it fell down and kept me out quite successfully. Truth be told, easier for an intruder to just take a crowbar to a sliding door and bust it out if they wish.

When the magnetic connection between the two parts of this sensor is broken, your alarm system will register an open condition. I guess if the window or door is struck in such a way that would cause the sensor parts to move enough to break the magnetic contact it might trigger the alarm. However, I think they were only meant to register open or closed.

It takes about 10 lbs of pull to make my door release from the magnetic door stop. That is added to a large spring's tension trying to close it. So if you can measure the force trying to close your door, and it is less than say 8-10 lbs, might just work. You could always buy one, try it. Amazon often has "used" units a a nice discount.

Mine is a an old ADT system and it works. The piece that goes into the door is only a magnet. It's pretty simple technology. When it moves away from the wired part it activates the Alarm. I think would work on most alarms.

Hi Hal, our doors are big and heavy and this does not work very well on them. The hinge pin is 3.5 inches, so we are thinking that this may not be long enough for you if you need 4 inches. Hope this helps.

When you go to tape it, measure first, then find a place on the door to stick the tape closer together, it might make a small gap in the top but when it closes by the magnets it should be ok

Yes. You need a bit of room on either side of the closure (door/frame) for the metal plate. If there is wood-trim too close to the edge it will be slightly loose but still effective. The idea is to prevent casual entry, to make noise if tampered with, and to slow down a thief while the alarm is ringing. Most thieves want to be in and out in minutes and this adds another problem to their navigation.

If your door works with a standard doorknob, it will work with this. If not, you'll need to get crafty.
