Q: Can I use both bars together for 1 patio door? I need a bar that is ~45.5 inches long, and I couldn't find any online but these 2 together might work

Hi,Though combined, the length would work, we would not be able recommend you use the products as you described for burglary protection. With enough force, it's possible that one bar would push up against the other and cause them to jackknife and fail to work. Thank you.

Q: How are these childproof? I have a 3and half year old who can reach the window. Thank you.

The Lock-it Block-it devices are placed in the top half of the window, wedged into the top corner of the window and held secured by adhesive strips which make it difficult for a child to pull off. A small child should not be able to reach that height unless there's furniture placed next to the window. Per child safety experts, no furniture should be placed near a window that allows a child to climb up on a window. When the device is adjusted to that the bottom half of the window can't be opened more than 4 inches, the child should be safe from accidental falls. Thank you.

Q: Can this be permanent to where a teenager can’t tamper with to sneak out of the house

No. They are velcroed to the window so a teenager can pull it off to leave and put it back on when he returns. I imagine that you can screw the device into the window frame, but then it can’t be easily removed if there is a fire. Of course, it is much more likely that a teenager will sneak out... (I had 3).

Q: my window opening from the top down is 13" . This is the part where I need to put this bar. Is there one small enough?

Mine is not that small and I don't know if they make one smaller. I suggest you call the manufacturer and ask them.

Sturdy, easy to use

This is an extraordinary item, something that I did not even know existed until I accidentally found it on Amazon. The window shown in the picture has a broken piece of hardware that cannot be replaced. A new window seemed the only option. Lock it Block It is the perfect solution. Clear directions, easy to use, perfect fit, and an added bonus of additional security. I am VERY PLEASED!

Works beautifully, feel safe!

I purchased this as I love having my windows open during the day, and night, but where I am renting they don't have locks that allow you to only open it a few inches. I wanted to be able to leave them open while still feeling safe. These are everything I could have asked for and more. I was worried about a few of the reviews saying the sticky tape wore down and it rendered them useless, but what I think they did was only use one of the tapes given. You need to use all of the tape - three for each item! They will NOT move at all once you do that. I've been able to have my windows open throughout the day and night, get some fresh air blowing through, without the worry of someone breaking in. I didn't really want to spend the money initially, but these are well worth the price. Piece of mind is priceless, safety is priceless. This company seems to be high quality and I'm thankful for my purchase. 10/10!

Extension

It worked fine and was easy to handle but it doesn’t seem sturdy when it’s extended outward.

Measurement misleading

I wish it gave the measurements from each hole. I measured the window and per the listed measurements, it should have fit perfectly, but the holes to lock in place, actually don’t work for the measurement at all, so it doesn’t really work :/
