I bought these to fix the armoir drawer which my wife loves. The original slide would no longer allow the drawer to open. I bought a pair locally but they were 1/2" wide. They were too wide and the drawer didn't fit back into the piece of furniture. I know, I know. I measured more accurately, but I didn't. So I bought this pair they were correct 3/8 they fit perfectly they work great now the obvious this is a 3/4 lengthening I was about to go into enforcement but like I said they didn't fit it lies not the manufacturer, i'm just a bit stupid, i would definitely recommend them, they worked great, i'm very satisfied.
