Full-Extension Soft-Close Undermount Slide Built for Both Cabinet Styles

The Grass Elite Plus 18 inch undermount drawer slide is a concealed, full-extension runner with integrated soft-close, suited for both face-frame and frameless cabinets and built for drawer boxes with sides up to 5/8 inch thick.

Key Features

• Full extension brings the entire 18 inch drawer box out to the cabinet face, so every inch of the interior is within reach.
• Integrated soft-close catches the drawer near the end of travel and settles it shut silently without slamming.
• Dual cabinet compatibility lets this slide install in face-frame and frameless cabinets from the same SKU.
• Roller-bearing carriage on a zinc-finished steel body delivers smooth, quiet travel under load.
• 75 lb weight capacity per pair handles most residential kitchen and bath drawer applications.

Where This Slide Does Its Best Work

An 18 inch undermount is the standard length for base cabinet drawers in kitchens and bathrooms — long enough for a typical 18 to 21 inch deep box while keeping clearance behind the rear of the slide. Because this model works in both face-frame and frameless construction, it fits naturally into a mixed shop where both cabinet styles run through the same build schedule. Shops can stock one slide length and deploy it across American face-frame kitchens and European-style frameless cases without carrying two separate SKUs. At 75 lb per pair, it is well within range for loaded utensil drawers, spice pull-outs, and bathroom vanity drawers — applications where full rear access matters and a clean, hardware-free look under the box is expected.

Construction and Finish

Steel members with a zinc finish provide durable, corrosion-resistant performance in indoor environments. The roller-bearing carriage runs quietly along the full length of travel and holds its motion quality through repeated cycles. Because the slide mounts concealed beneath the drawer box, the zinc finish is a functional one — it never shows when the drawer is open. The integrated soft-close damper is built into the slide body rather than added as a separate accessory, which keeps the installation straightforward and the mechanism consistent from drawer to drawer.

Who Orders This Slide

Production cabinet shops find this slide useful when the project mix includes both cabinet constructions — the dual-compatibility means fewer line items to manage and fewer ordering decisions per job. Residential designers specifying concealed slides for kitchens and baths get reliable soft-close and full extension without stepping up to a synchronized or multi-axis adjustment system. Contractors doing install work in mixed-construction projects can pull from the same stock for every run. In face-frame installations, the slide's rear end requires the matching Grass Elite Plus rear mounting brackets, sold separately and specific to the Elite Plus series — order these alongside the slides to avoid a second shipment on the job.

Concealed Performance Across the Cabinet Schedule

One slide length, two cabinet styles, consistent soft-close on every drawer — the Grass Elite Plus 18 inch is a practical choice for shops and contractors who want full-extension performance without managing separate SKUs for every construction type.
