Blum TANDEM 18 inch drawer slides provide a soft-close Blumotion action that cushions drawer travel, which helps cabinets close quietly in everyday use. As full extension undermount drawer slides, they let the drawer open its full length, so contents remain reachable from front to back without awkward stretching. The heavy duty TANDEM design is built as an undermount slide, so it supports the drawer from below and leaves the sides clean for a finished appearance. These Blum TANDEM slides use a roller bearing system in a zinc construction, which creates a consistent running motion that supports repeatable operation in busy cabinet applications. The Blum, Inc. branding and TANDEM Blumotion name identify a system used widely in professional cabinetry, which helps align this slide with common shop and jobsite expectations. Part number 569F4570B defines this exact 18 inch heavy duty configuration for repeat ordering and layout planning.
This TANDEM undermount drawer slide mounts beneath the drawer box, which keeps hardware out of sight and leaves the side profiles open for clean cabinet lines. Because it is a full extension 18 inch slide, drawer geometry can be planned so the usable interior depth tracks closely with the slide length, helping layouts that rely on predictable clearances. The soft-close Blumotion feature operates within the slide mechanism, so the closing action is integrated into the undermount system rather than added separately. As a heavy duty TANDEM model, this Blum slide is positioned for drawers that experience more frequent use, helping maintain consistent motion where standard undermount slides may be less suitable.
The Blum TANDEM 18 inch soft-close Blumotion full extension undermount drawer slide fits into drawer projects that call for concealed hardware and a controlled closing action. Because it is categorized specifically as an undermount drawer slide, it suits cabinetry where the drawer box is supported from below rather than along the sides. The 18 inch length supports drawer designs sized around that depth, which is common in many cabinet runs using standard carcass dimensions. As part of the Blum TANDEM Blumotion family, this slide aligns with other Blum undermount components used in residential or commercial cabinetry, allowing shops that standardize on this system to stay within a familiar platform.
The heavy duty TANDEM designation signals that this Blum 569F4570B slide is engineered for more demanding drawer use, which supports installation in cabinets expected to see frequent opening and closing. The roller bearing zinc construction contributes to stable motion, which helps drawers track consistently under load over time. Full extension travel allows the 18 inch drawer to move completely out of the cabinet, giving installers and users predictable access to the full drawer box. Soft-close Blumotion integrated into the slide body slows the final part of the closing stroke, which can reduce impact stress on the drawer front and cabinet face. The manufacturer part number 03067970 ties directly to this configuration, helping shops specify and reorder the exact same undermount slide when repeating a successful setup on future jobs.
