How to Install Drawer Hardware or Drawer Glides
There is simply no standard answer for installing drawer hardware. Installation should be done following the instructions included with the new hardware. If none was included, return to the store you purchased it from and ask for instructions. If none are available, don't use it. Return it and find another system.
Most cabinets are 24" deep on the outside and 23" deep inside. Usually, 22" side-mount slides with back mounting sockets will work nicely. Inspect the opening and note anything that will conflict with the new hardware. If you see a problem, explain it to your hardware sales person and he/she will suggest the right system.
