Grass Elite 21 inch soft close undermount drawer slides are full extension slides designed to mount beneath the drawer, so the hardware stays out of sight while the drawer travels its full length. The Grass America Elite design connects the drawer box to an undermount slide set, giving a smooth guided motion that supports everyday cabinet use in kitchens, baths, and built-ins. A soft-close function is built into this slide system, so drawers decelerate at the end of travel rather than stopping abruptly, which helps protect fronts and minimizes impact on the cabinet. The 21 inch nominal length targets standard-depth drawer boxes in common cabinet layouts, letting installers match the slide length to typical base and vanity depths. These slides are part of the Grass America family, so they align with a professional-grade hardware mix for cabinet shops and serious projects.
These Grass Elite undermount drawer slides are configured as full extension slides, so installers can position the cabinet member in a standard 21 inch slide layout and know the drawer will reach full travel. The undermount format means the hardware attaches along the underside of the drawer box instead of the sides, which affects how the drawer is built and notched. The 13365S-12 designation identifies this specific Grass America undermount model, allowing shops to call out the exact slide when repeating a successful cabinet run. Because these slides sit under the drawer, side clearances are freed up for drawer box design details such as thicker sides or applied inner panels. The soft-close action built into this Elite slide set also reduces closing shock on joints, which is helpful when combining these slides with fine joinery or delicate front materials.
The Grass Elite 21 inch soft close full extension undermount drawer slides suit cabinet layouts built around a 21 inch slide length, aligning with many base and vanity cabinet depths in residential and commercial work. Because the slides mount under the drawer, they are well suited to face-frame or frameless designs where a clean interior appearance is valued, such as kitchen drawers, bathroom pullouts, and office casework. The Grass America Elite construction with roller bearing zinc components supports drawers that see regular opening and closing, matching the duty cycle of everyday storage in occupied spaces. The soft-close feature with a liquid damper, as identified in the product description, helps control closing speed on loaded drawers, which is useful in family kitchens, rental units, and shared workspaces where drawers are used by multiple people. The 13365S-12 part number ties this slide format directly to Grass documentation and project specifications, so designers and builders can reference a consistent undermount slide when standardizing a line of cabinetry.
The full extension travel on this Grass America undermount drawer slide means installers can design drawer boxes to utilize the full 21 inch slide length, reducing wasted depth and improving storage capacity in each opening. The soft close action built into the Grass Elite mechanism, combined with a liquid damper, cushions the final portion of travel, which helps protect drawer fronts, face frames, and contents from repeated impact over time. The undermount location of the 13365S-12 slide allows consistent reveal and margin control along drawer sides, because no side-mounted hardware interrupts clearances or interferes with drawer side thickness choices. Roller bearing zinc construction guides the drawer along a predictable path, supporting square alignment between the drawer front and cabinet and helping reduce call-backs related to rough or uneven slide performance. For shops standardizing on a specific undermount system, the clear Grass Elite and 13365S-12 identification lets purchasing, production, and installation all reference the same slide, improving consistency from build to field install.
