Blum 554H Tandem Edge 18" Soft-Close 7/8 Extension 100 lb Undermount Drawer Slide, Zinc, 01662432

Zinc Undermount Drawer Slide For Economy Concealed Installations

The Blum TANDEM Edge is an 18 inch undermount drawer slide built for shops that want the clean, concealed look of an undermount runner and integrated soft-close without paying for full-extension travel. It carries drawer boxes with 1/2 to 5/8 inch sides in both face-frame and frameless cabinets, rated 100 lb per pair.

Key Features

• 7/8 extension opens nearly the full drawer length with only a small extension loss — the rear few inches stay inside the cabinet.
• Integrated BLUMOTION soft-close catches the drawer near the end of travel and settles it shut silently without a slam.
• 100 lb weight capacity per pair covers typical kitchen and bath drawer loads.
• Suits face-frame and frameless cabinets — select the rear hardware that matches your construction.
• Roller-bearing carriage on a zinc steel body delivers a smooth, quiet pull through years of indoor use.
• 3/16 inch side clearance keeps the box-width formula straightforward for dovetailed and doweled box builds.

Where the TANDEM Edge Fits the Job

Production cabinet work often calls for a concealed undermount slide and a soft-close close — but full extension is not always on the spec sheet or the budget. The TANDEM Edge lands in that gap: it hides under the box, closes on a damper, and opens far enough that daily-use contents at the front and middle of the drawer are fully accessible. A breakfast-nook drawer, a bathroom vanity, a laundry-room base cabinet — anywhere that needs a tidy concealed runner without the cost premium of a full-extension model. If your client or plan calls for rear-of-drawer access on every pull, step up to the full-extension TANDEM plus BLUMOTION line instead; for everything else, the TANDEM Edge performs the task cleanly.

Build and Finish

Steel members with a zinc finish handle the structural load and protect against the humidity swings typical in kitchens and bathrooms. Because the slide mounts beneath the drawer box and stays hidden when the drawer is open, the zinc finish is functional rather than decorative — corrosion resistance for indoor service is what matters here, and that is what zinc plating delivers. The roller-bearing carriage runs quietly and stays smooth under load without the noise or stick common in economy epoxy slides.

Who Orders This Slide

Cabinet shops running mid-range residential work are the natural fit: the TANDEM Edge gives them a Blum soft-close undermount at a step-down price compared to the full-extension 563H family, without dropping to a non-damped economy runner. Designers specifying value-line kitchens or bath vanities get a clean interior look and quiet close. Contractors replacing worn slides in existing frameless or face-frame casework find it straightforward to source and install. The 18 inch length suits standard 18 inch nominal base and vanity drawer boxes built to Blum's published specification for the 554H series.

Soft-Close Concealed Performance at the Right Price Point

The TANDEM Edge delivers Blum's roller-bearing quality, integrated BLUMOTION soft-close, and a clean undermount profile for production jobs where full-extension travel is not the deciding factor — making it one of the more practical concealed-slide choices at this capacity and price class.
