The Grass Elite 21 inch undermount drawer slide is a 3/4-extension concealed runner with integrated soft-close, rated 75 lb per pair and suited to drawer boxes with sides up to 3/4 inch thick. It fits both face-frame and frameless cabinets and brings a damped, quiet close to production and value-tier work without stepping up to a full-extension model.
Full rear access is not always the goal. Vanity drawers, pantry pull-outs with frequently reached items, and secondary storage drawers where the front half of the box is all that gets used regularly are natural fits for a 3/4-extension slide. The 21 inch length suits standard base cabinet depths, and the 3/4 travel means the back few inches of the drawer box stay inside the cabinet at full open. If a job spec requires the complete drawer interior to come all the way to the cabinet face, this is the wrong model — step up to the Elite Plus full-extension line for that application. For everything else, this slide installs cleanly, closes quietly, and keeps the slide cost in line with a value-tier build.
Steel members with a zinc finish handle years of indoor service without issue. The roller-bearing carriage keeps the pull smooth under load, and because the slide mounts beneath the drawer box, the zinc finish is a functional coating rather than a visible design element. The soft-close mechanism is integrated into the slide body — no separate damper to install or adjust.
This slide is a practical choice for production cabinet shops running mixed face-frame and frameless work and for contractors replacing concealed slides on existing casework. It also suits homeowners and designers specifying value-tier vanities or secondary storage where full extension is not a requirement. The 3/4 inch maximum drawer side thickness covers the majority of solid wood and plywood box constructions without needing the thinner 5/8 inch version.
At 3/4 extension, the drawer travels roughly three-quarters of the 21 inch slide length. The rear portion of the box stays inside the cabinet at full open. If you need the entire drawer contents reachable, choose a full-extension model instead.
Face-frame installs require series-specific rear mounting brackets to support the back end of the slide. The brackets are sold separately — do not skip them, as the slide's rear end has no cabinet side to fasten to in a face-frame box.
Front locking devices for the Grass Elite series are series-specific accessories. Confirm whether they ship with this SKU or are ordered separately before building the drawer box, as the box drilling depends on the locking device used.
Yes. The maximum drawer side thickness is 3/4 inch, so 5/8 inch material falls within the acceptable range. Build the box to the Grass Elite specification for this series, including the correct width formula, bottom recess, and rear notch.
75 lb is the per-pair rating — the combined capacity of both slides carrying one drawer. Do not double it.
When the job calls for concealed slides and soft-close in a build that does not need full rear access, this 21 inch Grass Elite undermount delivers the features that matter at a spec that fits the budget.
