How much force on the door can this withstand before breaking?

since these protect the doors that are in a closed position from being opened it would take a lot of force although with a crow bar you can get into any door/window no matter how secure

Open the door and hold at a 45degree angle from base of camera and pull it out of the groove don't worry it shouldn't break

I can't see where it would damage the door. That said, where I live right now, I am using it on a metal door. I can say there have been no indentations or anything to the door. The piece is small, but holds securely.

It should be fine. It's got substantial weight to it and doesn't move around when you open or close the door

I can't really answer that with certainty. I have two of them on heavy metal screen doors that probably weigh about 150 pounds apiece and it closes them well. I don't really know how heavy a door it really will work on. I don't think it said on the box the new one came in. These were originally installed by the screen door company and the reason I had to buy a new one was there was a person who could not seem to understand that sometimes I wanted the door to remain open and they insisted on pulling it shut without disengaging the detent that works to hold the door open. So when they broke that I had to but a new one. Sorry I can't help you more. I can't really answer that with certainty.

I can't speak for others but I've used this pretty heavily since I got it about a month ago and it seems very strong. I can see where someone could break it though...the hinges and panels are from the same molded plastic so if you're very rough with it or bend it improperly it will definitely snap.

Other than the large dog that may be inside, there is nothing to stop this. There is a thick plastic insert that blocks easy entrance when you need it, but technically if they wanted they could break the whole thing off. But really they could break through a window or flimsy door just as easily.

No it doesn't put too much strain on the door. The force is distributed accross the entire door so no one part of the door gets overstressed

Ours has been on our fridge for almost 1 year now. I have several times yanked on the door forgetting it was there and it is still stuck as strong as the first day I put it on! It has survived parties from adults yanking on the door not realizing it is there as well. I think you actually have to pry it off of the door when you are ready to remove it.

You won't break it, just pull apart front and back pieces - were the opening for connector is. It does feel like it gonna break , but it won't.

Haven't measured it, sorry. You're unlikely to break it unless using it as a pry bar on something you shouldn't. Even so, this thing is heavy duty enough.

That would depend on the door. The narrow edge should be able to be wedged into the crack of any door I've seen, but unless the metal is just a thin skin on a light frame, it probably does not have the length to give you enough leverage.

A single roller does not support the entire weight of the door, so this should not be alarming. That means that using this particular roller on a door with ten rollers on it, the rollers could lift a 1250lb door that is 12 ft. high approximately 50,000 times before it breaks.

If you have solid wood doors I would go with 3 hinges per door with the upper and middle closer together than the middle and lower. Can't say for sure pounds max, but there is a lot of force exerted on that top hinge. I tried them on a church door that had leaded glass window and it was too much for even the 3 hinge setup. Light weight or hollow door, 2 should work.

My husband has used ours for several months now and it hasn't done any damage. If installed correctly, it shouldn't damage your door.

On one of my doors, I have a hair-width crack in the drywall. It's stretching out at a diagonal from the corner of the frame. It's almost invisible, unless it's daylight, and then you'll notice it's a little over a foot long. This was caused by one of my friends trying to do a pull-up on it at one point. I estimate he weighed 180-200 lbs at that time. I've since stopped using it on that door frame and moved it to another one, and so far no cracking. Been using it for 2+ years now.

Doubt it'd break, but yo might need to add a longer "rope" or maybe just extend the existing one. The metal and working parts should be fine no matter what size door as long as the top section fits the thickness of the door snuggly
