Zinc Undermount Drawer Slide For Compact Cabinet Drawers

This is Blum's TANDEM plus BLUMOTION undermount drawer slide in the 12 inch length — a fully concealed, full-extension runner with integrated soft-close, rated 90 lb per pair, built for drawer boxes with 1/2 to 5/8 inch sides.

Key Features

• Full extension — brings the entire 12 inch drawer out to the cabinet face for complete access to the interior.
• Integrated BLUMOTION soft-close — a built-in damper catches the drawer near the end of travel and settles it to a silent close.
• 90 lb weight capacity per pair — rated for loaded spice, utility, and vanity drawers in this length class.
• Fits 1/2 to 5/8 inch drawer sides — compatible with standard dovetailed and doweled drawer boxes in this thickness range.
• Suits face-frame and frameless cabinets — one slide works in both construction styles with the correct supporting hardware.
• Steel construction with zinc finish and roller bearings — provides smooth, quiet travel and lasting indoor durability.

Where the 12 Inch Length Fits the Job

The 12 inch slide is the right choice for shallow base cabinets, bathroom vanity drawers, and upper-cabinet pull-outs where cabinet depth rules out a longer slide. It handles spice drawers, cutlery inserts, and small accessory compartments that would be over-built with an 18 or 21 inch runner. Because TANDEM plus BLUMOTION is a full-extension design, the entire drawer box comes to the face — useful in shallow applications where the last few inches of depth are exactly where the contents live. The 90 lb per pair rating is more than adequate for the loads these drawers typically carry.

Materials, Finish, and How the Slide Stays Hidden

The steel members carry a zinc finish that protects against corrosion through years of indoor service. Roller bearings run in precision-formed raceways, keeping travel smooth and quiet under load. Because the slide mounts beneath the drawer box rather than alongside it, the hardware is invisible when the drawer is open — the only view is the drawer box itself. The zinc finish is functional rather than decorative, since the installed slide is fully concealed.

Who Should Specify This Slide

Cabinet shops building bathroom vanities, kitchen spice towers, or any shallow drawer run where a 12 inch concealed slide fits the case depth will find this the straightforward choice. Designers specifying premium residential work get the BLUMOTION damping and full-extension access they need in a compact format. Homeowners replacing worn runners in shallow drawers get an upgrade to concealed hardware without changing the drawer box, provided the box already meets the Blum specification for this series. The slide suits face-frame and frameless construction equally — the cabinet type is covered by hardware selection, not by swapping slides.

The Right Concealed Slide for Shallow Drawers

When the cabinet is shallow and the drawer still needs to fully open and close silently, the 12 inch TANDEM plus BLUMOTION delivers exactly that — full access, 90 lb capacity, and BLUMOTION soft-close in Blum's most compact undermount length.
