The Blum TANDEM 18 inch undermount drawer slide with BLUMOTION brings full-extension travel and integrated soft-close damping to kitchen, bath, and furniture drawers in both face-frame and frameless cabinet constructions. Sized for 18 inch drawer boxes, it runs on roller bearings in a zinc steel body and carries 90 lb per pair.
An 18 inch undermount slide lands squarely in the range of everyday kitchen and bath drawer work: base cabinet drawers, bathroom vanity drawers, and bedroom furniture pieces where a concealed slide and a quiet close matter to the finished result. Full extension means a cook reaching for a pot at the back of the drawer or a homeowner sorting through a cluttered vanity drawer gets unobstructed access to the whole box — not just the front two-thirds.
The dual cabinet-type compatibility earns this slide a place on mixed job lists. A contractor finishing a traditional face-frame kitchen and a shop building frameless euro-style boxes can pull from the same stock without stocking two different slide versions. In face-frame installations, rear mounting brackets are required to support the slide's back end — those brackets are sold separately and are series-specific to the TANDEM line.
The slide body is steel with a zinc finish, giving it the corrosion resistance expected of a long-service indoor installation. Roller bearings carry the load through the travel cycle — the same bearing system Blum uses across the TANDEM line for consistent feel across a project. BLUMOTION damping is integrated into the slide, not a bolt-on accessory, so there are no extra parts to source or install to get the soft-close function. The drawer box must be built to the TANDEM nominal specification for an 18 inch slide, with sides between 1/2 and 5/8 inch thick, and must include the rear notch and any locking-device drilling the Blum spec sheet calls out.
Cabinet shops running Blum hardware throughout a project reach for this slide when the drawer is 18 inches deep and the design calls for a clean, handleless-ready undermount with a silent close. Designers specifying premium residential kitchens or bath remodels rely on the TANDEM line's consistent quality across a full project. Contractors who need a slide that works in both frame and frameless boxes on the same job site benefit from not having to manage two part numbers. And homeowners replacing worn or noisy slides in an existing kitchen get a direct path to the quiet, smooth close the TANDEM with BLUMOTION delivers.
Yes. In face-frame cabinets the slide's back end needs support from rear mounting brackets. Those brackets are sold separately and are specific to the Blum TANDEM series — pick them up when you order the slides.
The slide is engineered for drawer sides between 1/2 inch and 5/8 inch thick. Build the box within that range and to Blum's published 18 inch nominal specification.
It is integrated into the slide. There is nothing extra to order or install to get the soft-close function — the damper is part of the slide as it ships.
The TANDEM series is compatible with Blum's TIP-ON and TIP-ON BLUMOTION units, but those are ordered separately and matched to the TANDEM program specifically. Confirm the correct TIP-ON unit for this slide series before ordering.
Per pair. One pair of slides — one on each side of the drawer — carries the 90 lb rated load together.
When the drawer needs to open fully, close silently, and disappear beneath the box, the Blum TANDEM 18 inch with BLUMOTION delivers all three — in face-frame or frameless cabinets, on sides from 1/2 to 5/8 inch thick, at a 90 lb working capacity built for real kitchen loads.
