How many wedges does it take to secure one window?

I go with 1----but my wife sats 2 whick is overkill... mu child who is 4 has attempted a couple times to open and cannot what so ever... I am a retired firefighter and if I thought 2 was needed I would say if you want to spend the money then go for it,,,,,trust me 1 is enough.....

It should take just one depending on the type of window. They didn't work on my vinyl windows. Not enough space to allow the wedge to go under the window.

I put just one on each window, and they work wonderfully. In fact, I'm about to order some more for another 2 rooms in our house.

I'm not sure if it will secure the outside, but I have two placed on each window, which prevents someone on the outside from being able to pull up the window. I hope this helps!!!

no just need one for each window they stretch far enough to cover the entire length.

There are four pieces. If you were to install the unit on one side there is enough for four. If you want one one each side there are two

I would use eight of them. I bought four, and though they held, I was much more secure when I bought an additional four and added them. They just do not cost that much for the peace of mind. Hope that helps.

House was built in 46 - these worked perfect - I just used 1 per window - I put at height that I could open window to get fresh air yet someone else could open window anymore to get in. These work perfectly. V is n hinge, once you open up you can slide window past.

I can on my window, not sure about all windows, but I can open my window all the way on mine if I take out the wedge.

only one for each window , however they do fit back windows better than front because of front slop. thats why some people say you need more than one for each window. I have two and use them on the back windows and the provide plenty of air.

If you are handy and have a hack saw and a file (to smooth off the rough edges), you could cut down the two U-shaped brackets to fit in your cabinet and attach only one . You would be making 4 cuts

This is just 1 wedge. I only ordered one not knowing how it worked and it works ok as far as holding, but we have not had any really strong winds since my purchase. I think that perhaps 2 wedges would be better.

I've found that I need at least 5 on a large window...spaced randomly, maybe 2 feet apart. Even then, we occasionally get a bird that doesn't see them! So, I guess a good rule of thumb would be the more the better!

You will need two. We have wood and glass doors into our library hanging from these.

Mine is mounted with decent-sized screws to a concrete wall, and the case itself seems pretty tough. It would be hard to pry off, and would hopefully draw some attention from the neighbors, but I'm sure it's possible. With 12 buttons there are also only 4096 combinations, so someone could also defeat it that way. But it's a lot better than hiding a key. For that matter, what's to prevent someone from prying your door open?

One person can install the brackets for the awning, however to put the awning into the brackets and fasten it you need 2.

Only one and make very sure someone with steady hands.installs the safe. I don't and tried to move it.I messed up.

Two or three on each window should do it. I would cluster them pretty close together in the area where birds most often hit you windows. Our seem to have helped; fewer bird strikes.

That is a good question. My window opens out. I am not sure. I have secured my shelf with screws. I guess it depends on the screen.
