Synchronized Soft-Close Full-Extension Undermount Drawer Slides

Concealed undermount slides with synchronized full-extension travel, soft closing and reduced opening force. A rack-and-pinion mechanism keeps the slides moving together to reduce racking on wide or heavy drawers, without an additional stabilizer bar. Select the length of your drawer box to choose the matching pair.

Performance and construction

• USMAX2S synchronized series, sold as one left-and-right pair.

• Manufacturer-advertised 120 lb dynamic load rating. The linked independent report documents an 18-inch USMAX2S-18 pair passing 50,000 cycles with a 120 lb drawer test load.

• Zinc-finished steel for face-frame or frameless cabinetry.

• For drawer-box sides 1/2 to 5/8 inch thick; follow the factory notching, boring and clearance requirements.

• Slotted mounting holes support alignment during installation.

• Attachment clips, mounting screws and rear brackets are sold separately. Face-frame installations require compatible rear brackets.

• The 9-inch option requires USE-STEEL-309 rear brackets when used in face-frame cabinetry.

• Compatible release clips: USMAXCLIPN, USMAXCLIP4W, USMAXCLIP4WZ or USMAXCLIP6WZ. Choose the clip for your drawer width and desired adjustments.

Choose your drawer-box length

The selected 9–24 inch size is the nominal drawer-box length, not the overall metal slide length. The factory guide provides these cabinet-depth limits for its standard installation. Inset fronts require additional setback; use the guide for final fitting.
