Knape and Vogt 18 inch soft close undermount drawer slides are designed as an 18 inch undermount drawer slide system that supports full extension and soft close action, which allows a drawer to open its full length while closing smoothly for controlled movement in everyday cabinet use. As an undermount drawer slide, this hardware mounts beneath the drawer box rather than on the sides, which keeps hardware out of sight and leaves the drawer interior width fully usable in typical cabinetry layouts. The soft-close full extension undermount design ties the slide length to 18 inches, which lets installers size drawer boxes and cabinets confidently around a known run length for consistent results on multi-drawer projects and repeat shop work.
This product is identified as an 18 inch soft-close full extension undermount drawer slide, so the 18 inch length provides a straightforward dimension for setting cabinet depth and drawer box length within that run to keep hardware travel aligned. Being in the product class of undermount drawer slides, it is intended to mount beneath the drawer box, which lets fabricators design drawer side thickness and clearance without allocating space for side-mounted slides. The soft-close function built into this undermount slide provides a controlled closing motion, which supports calm drawer operation in kitchens, baths, and built-in casework where repeated openings and closings are part of daily use.
The manufacturer part number KVGS-2070B 18 identifies this hardware as an 18 inch G-Slide undermount slide, letting installers call out this exact slide when coordinating shop drawings or replacements. Its listing under Drawer Slides and Slides, Undermount positions it for cabinet and furniture drawers that benefit from concealed hardware, such as kitchen base cabinets, bath vanities, or office casework that favor a clean interior look. The soft-close full extension description tells builders it is suited for drawers that need full access to contents along the 18 inch depth while still returning softly, which supports storage layouts where the entire drawer length must be reachable without forcing or slamming during repeated operation.
The designation soft-close full extension undermount drawer slides means this Knape and Vogt slide is built to travel the full 18 inch length before the soft-close action engages, which provides predictable access to the entire drawer box on an 18 inch run. Because the slides are described as roller bearing zinc, the movement relies on a roller system within a zinc-related construction, giving a defined rolling motion that can feel consistent across multiple drawers built to the same spec. Using an undermount drawer slide instead of a side-mount pattern keeps hardware hidden under the drawer box, which can help designers maintain clean side profiles and full internal width while still benefitting from the soft-close feature in normal cabinet use. The 18 inch length and defined product class give shops a repeatable standard when producing banks of drawers that all share the same hardware behavior and travel distance.

The undermount design places the slides under the drawer box instead of on the sides, allowing the drawer side walls and interior width to be used without allocating space for side-mounted runners.
These drawer slides are described as roller bearing zinc, meaning the motion is handled by a roller-based system in a zinc-related construction for defined rolling movement.
