I ordered 8 pairs 14" and one pair 24" length for a built in dresser drawer project with side design. Everything came quickly and in factory condition. However, I have a few points about the product that I can mention that might be helpful to others: 1. No instructions included. (ROK's YouTube video was utterly useless -- it was made by marketers who had no idea what product installers could do.) Unlike other manufacturers, there's no left/right separation. The right side of the box gets the "right side up" block. You will understand.2. A gap error is permissible for lateral attachment to the cabinet walls. Leave exactly 1/2 inch on each side. Possibly 17/32 inches. This is not so important when mounting to the back of a cabinet, but please note that mounting brackets are not included for this arrangement.3. The mounting screws pierce the 1/2 inch wall of the drawer. durable and the soft close mechanism is consistent and magical. I hope to be happy with them all the time.
