***All of the requirements for this type of slide should be considered before the drawer box is purchased or built.***

Undermount slides have very specific allowance requirements.
Make sure to check the spec sheet for the slide chosen.

  • The width of the drawer will depend on slide chosen and the side-to-side clearance needed for that slide. Side-to-side allowances range from 3/8" overall to 1/2" overall, depending on series chosen.
  • Depth of the drawer should match the slide chosen. (I.e., If you choose an 18” drawer slide, the drawer box will have to 18” deep also, and so on.)
  • This type of slide also has specific height allowances.
