How does it lock into place and stay up?

I use the screen in an Andersen window - sides of screen fit in the window tracks, bottom of window rest on top of screen. It does NOT lock in; however, it does close up relatively well.

The clips are pretty strong and keep the screen extended even when used vertically.

It has a "3-sided" bracket that hooks over the top. It stays in place but is not secured to the bed.

Love mine! The knobs lock in place at whatever you set them to. They're not prone to loosening on their own. Set it and forget it!

I agree with the other answer - it only locks when it's in the upright position.

I'm not sure. When you are putting it up, just raise it to the height you want, but I don't know if there will be a locking device at that spot, but you could devise one.

Doesn't need locked in. The weight of the tv keeps it from moving much. I just moved it up or down and then left and right when I installed it and have not moved it since. Very heavy duty and does the job.

no it doesnt snap into place nor is there some sort of locking mechanism. the legs simply angle outward, thus removing any possibility of buckling or collapsing.

Mine rolls up fine.So if you pull down slowly it stays where you put it, if you pull down quickly (just an inch or so) and let go it rolls back up.

It does not lock in place, just folds from one position to the other. It's pretty secure. We've all all manners of shapes, sizes and ages on them and not had any issues.

You have a keyhole for the board to snap into. Drop the board into the larger part of the keyhole and push it back to jam it into the narrower part of the keyhole that should keep the board in place.

It is designed to hold that, the one I purchased was broke and would not stay up. I returned mine for a refund and purchases another brand and model.

They stay up but I don't remember them locking in place. I remember just folding them down to use.

It's locked in the up position and stays in line. When pushed to the side it's not locked but it's not flopping around either. It stays put until you pull it back up.

It only locks in an open position. When closed it is in an unlocked state (allowing gravity to do its thing).

It's a little tricky, if you twist the top one way it locks. And if you push it down when in the lock position it can get stuck. So keep wiggling it, till it goes down easily, just may take a little getting used it.

It stays up just fine, at least mine does because it is full. If it only has a few dvds then you may have to spread them out to balance the weight so it doesn't fall.

Watch the video on their web page, it show in detail how to do it. It's in there tight, but I like that it won't slip/fall out of the shell!
