Ever want your slider to be partially open exactly where you want when you're parked on a slant? To keep sun off the fridge, or provide just enough privacy? I've made an easily adjustable and removeable slider stop that simply clips into the top rail. Roll completely over it to open or shut the door like normal, or put it exactly where you want your door to stop and ease up to it to keep your door in place. Unique spring mechanism holds it onto the rail. Simple. Easy. Tuned for easy stopping and easy opening.
