It's overkill but I have leftover 3/4-1" that I want to build some drawers with.** A: The space between the runner and the vertical part that attaches the slide to the cabinet side is only wide enough to accommodate 5/8" material. Blum does make the same slide that is for maximum 3/4" material, part number 563F5330B. Hope that helps! **Q: Are these the right slides for 24" cabinet depths using 1/2" sides, 3/4" face, frameless cabinets?** A: Yes, these are designed for standard 24" cabinets, frameless or face frame. The slides need 21-5/8" of inside cabinet depth to work so as long as you have at least that much you are good to use these! The 563H slides are designed so maximum 5/8" drawer box sides (1/2" or 5/8"). ## Frequently Bought Together - BLUM 21 Inch Drawer Slide, Full Extension, Concealed, Undermount. 563H5330B with 100 Lbs.
