Blum TANDEM 21 inch drawer slide defines this 21 inch soft-close undermount runner as a concealed solution for drawers where a clean cabinet interior matters. The BLUMOTION soft closing function controls final travel so drawers close quietly, which helps protect fronts and keeps motion controlled in everyday use. The TANDEM smooth running action uses Blum engineering to keep the drawer movement consistent from light to fully loaded, giving installers predictable performance across a kitchen, bath, or shop run. This model is a 7/8 extension concealed drawer slide, so most of the drawer box clears the face while the slide hardware stays hidden under the drawer, supporting a finished look on frameless or face frame jobs. With the undermount design, the slide supports the drawer from below, which helps keep drawer sides clean for contemporary construction and simplifies cleaning over time.
This undermount drawer slide is specified for face frame or frameless cabinets, so one model can be applied across different construction styles in the same project. Drawer thickness from 1/2 inch (13 mm) to 5/8 inch (16 mm) is supported, which defines the side material range that works with this TANDEM system in typical cabinet drawers. The roller bearing zinc construction supports smooth movement along the track, giving installers and users consistent operation under rated loads. Because the slide is concealed, it sits under the drawer rather than on the sides, which maintains the visual design of the drawer box and lets builders use clean side panels without side-mounted hardware interrupting the look.
This TANDEM undermount drawer slide is specified for face frame or frameless cabinets, so it can be used in traditional framed boxes or in frameless European-style runs without changing slide families. The 21 inch nominal length works wherever that drawer depth suits the cabinet interior, letting the installer standardize on a common depth for many base, vanity, or shop drawers. Drawer thickness support from 1/2 inch (13 mm) to 5/8 inch (16 mm) covers common plywood and solid stock used for drawer sides, which lets shops keep typical drawer construction and still use this hardware. As a concealed drawer slide, it places the running gear under the box, helping maintain uninterrupted drawer sides for design consistency across a full bank of cabinets.
The BLUMOTION soft closing function on this TANDEM slide manages the last part of closing travel, which reduces impact on drawer fronts and cabinet frames during day-to-day use. TANDEM smooth running action describes the guided motion along the length of the runner, so each drawer feels uniform when opened and closed, which is valuable when installing whole-room layouts. The 100 lb static load capacity and 75 lb dynamic load capacity define how much weight the slide is rated to support when still and in motion, helping designers and installers plan drawers that hold heavier items within those load expectations. As an undermount, this concealed drawer slide keeps moving parts protected below the box, which supports long-term function in typical residential and light commercial cabinet environments.
