From the Brand

Choose it for shelf-style pull-outs supported from below.

This is for bottom-supported trays, pantry organizers, trash-can pull-outs, and open shelf builds. It is not a universal drop-in replacement for every traditional side-mount or concealed drawer slide.

  • Pantry pull-outs
  • Trash can cabinets
  • Under-sink trays
  • RV cabinet drawers
  • Wardrobe organizers

Cabinet Fit

Cleaner pull-outs without visible side rails.

The rail supports the tray from underneath, making it useful for pantry shelves, trash cabinets, and compact organizers.

Mounting Logic

Support comes from the base, not the side wall.

This matters when the tray is open-sided, visible, or built from a solid bottom panel rather than a conventional drawer box.

Finish

Black hardware stays visually quiet.

The powder-coated finish fits dark cabinets and visible pull-outs better than bright silver hardware.

Fit Warning

Measure cabinet depth before choosing length.

Select a slide shorter than the inside depth and confirm the tray bottom can carry fasteners and daily load.

Product information

Measure before ordering.

Use the full chart for closed length, overall extended length, pull-out travel, side width, and profile height.

Before ordering
  • Confirm the drawer or tray has a solid bottom panel.
  • Choose a slide length shorter than the cabinet interior depth.
  • Keep left and right runners square before tightening fasteners.
  • Avoid side-wall-only drawers unless the base can carry the load.

Install & support

Questions that change the setup.

Is this the same as a side-mount slide?

No. It is a true bottom-mount slide for bottom-supported pull-out shelves and trays, especially where conventional side panels are absent or visible.

Will it close softly?

Yes. The slide includes damping for quieter, smoother closing under everyday cabinet loads.

    Easy to install and they carry the weight

    United States

    I wanted undermount drawer slides to hold a drawer in the bottom of a floor-level cupboard for flour, seeds, and other baking supplies; weight adds up! I mounted these to the bottom of the drawer first,…

    Coreax under mount shelf slides recommended.

    United States

    Strong, sturdy, well-built and operates smoothly. Some DIY experience or YouTube info helpful, as no instructions or template provided. Can customize to your own shelf dimensions, and shelf almost fully extends for good access.
