15 Inch Undermount Drawer Slide For Shallow and Mid-Depth Cabinet Drawers

The Blum TANDEM plus BLUMOTION 15 inch slide is a full-extension, soft-close concealed undermount built for shallower cabinet drawers — think bathroom vanities, desk pedestals, and upper base cabinet pull-outs where a shorter drawer depth calls for a precisely matched slide length. It carries 90 lb per pair, suits drawer boxes with 1/2 to 5/8 inch sides, and installs in both face-frame and frameless cabinets.

Key Features

• Full extension brings the entire 15 inch drawer box out to the cabinet face, putting every inch of interior space within easy reach.
• Integrated BLUMOTION soft-close catches the drawer near the end of travel and settles it shut silently, with no add-on damper required.
• 90 lb weight capacity per pair handles loaded vanity and utility drawers comfortably.
• Compatible with face-frame and frameless cabinets, covering the two most common cabinet constructions in one model.
• Roller-bearing carriage on steel members with a zinc finish delivers a smooth, quiet pull through years of daily use.
• Designed for 1/2 to 5/8 inch drawer sides, the most widely used thickness range for dovetailed and doweled drawer boxes.

Right-Sized for Shorter Drawers

The 15 inch length fills a specific role in a cabinet build: vanity drawers, small base-cabinet pull-outs, home office desk drawers, and any application where the interior depth lands in the 15 inch range. At full extension, the entire box clears the cabinet opening so nothing stays buried in the back. Matching the slide length to the actual drawer depth — rather than sizing up and shimming — produces cleaner installation results and makes the most of the cabinet's available depth. For builds that mix drawer heights, the 15 inch slide pairs naturally alongside longer slides in the same 563H series without changing locking devices or brackets.

Steel Construction, Zinc Finish, Roller Bearings

Steel members with a zinc finish resist the wear and humidity of everyday indoor cabinet use. Because the slide mounts entirely beneath the drawer box, the finish serves a functional purpose rather than a decorative one — it stays hidden when the drawer is open. The roller-bearing carriage keeps motion smooth under load, and BLUMOTION's integrated damper requires no separate installation step: soft-close behavior is built into the slide body, not bolted on afterward.

Vanities, Desks, and Shallow Base Drawers

This length is the go-to choice for bathroom vanity cabinet builds, where standard 15 inch drawer boxes are common, and for home office and built-in desk configurations with shallower pull-outs. Cabinet shops running production vanity lines benefit from a single slide model that covers both face-frame and frameless construction. Homeowners replacing worn slides in an existing shallow cabinet will find the 15 inch TANDEM plus BLUMOTION a direct-fit upgrade, provided the drawer box is built to Blum's published specification for this series.
