The hinges take the weight & will eventually loosen. The door itself will be fine. The same thing happens with those over the door shirt racks.

Thanks- I can't figure out what they can catch om either or why the sash cord rides up on the pulley in a couple of places. I DO know that the knots were originally nailed in and I did not do that when replacing them. When I was a kid and my father showed me how to do this, I don't think he nailed 'em in, but those were different windows in a different house. thank you, do you know if I will run into trouble if the cords are different lengths? I know that in my daughter's room I left them too long in one window and there's a window that opens easily but is really hard to get down, while other windows in the house operate easily with one hand.

If any of the cords are too long, you could have trouble. If, for example, one cord was too long on one side- so long that the weight bottomed out, it would tend to want to tip the sash to one side, making it bind. I saw a nice video once on this topic, I think it was a bob vila video. Yeah. Maybe you can find it if you google it. Use: bob vila sash cord in your search.
