A: Hello BrooksRobinson, Thank you for your recent inquiry about the 12 in. Full Extension Ball Bearing Side Mount Drawer Slide. This drawer slide is designed to be mounted directly to the cabinet. We cannot recommend mounting the slide to another slide. Thank you for shopping Home Depot. We appreciate your business and look forward to serving you in the future.
A: From reading the descriptions of the two series I found basically three differences. (1) The 1170 series is more expensive. (2). The 1170 series replaces two other series. (3) The 1170 series can be bought with a zinc coating.
A: Regular ball bearing slide. Not Barn Door Hardware. Used them in a desk I built. Worked well. Great pricde.
