Thanks Paul! I've seen something black on the outside, couldn't make it release at all. If the release is on the inside of the track, that will definitely be tricky. The drawers only come out about 1 inch from the frame of the cabinet when fully opened. I can't get my hand in there. I will investigate further and see what I can do. I was figuring the catches where available on Amazon. I just was trying to figure out how to get the drawers out first before I went looking.
