I think I have heard of these but no one at Home Depot could think of one. I'm trying to find a mechanism that will allow me to attach a horizontal upper mask to the inside of a wooden valance. This mask, made out of thin plywood painted black, needs a vertical sliding device that would have an "up" locking position to keep the mask hidden behind the valance when not in use. To activate the release of the mask you simply push up and the catch releases and gravity drops the mask. Think of drawer slides mounted vertically but only about six inches in length. There would be three of these catch and release slides; both ends and one in the middle. When the movie is over the screen is rolled back up and the mask is pushed back up until it catches and stays hidden.
Anyone know of this device?
