Where can i purchase a drawer slide rail?

Question

i've recently moved and during the move, one of the drawer slide rail from my dresser fell off and need to replace one.

Answer 1

Hardware stores such as Home Depot, Lowes, etc carry replacement drawer slides.  They come in sets of two, I suggest replacing both sides.  I would remove the old drawer rail and bring it the store to help find a replacement, several varieties are available.
