The Grass Dynapro 18 inch soft-close full-extension undermount drawer slide is a roller-bearing, concealed slide rated at 100 lb per pair, built for kitchen, bath, and furniture drawers in both face-frame and frameless cabinet construction.
An 18 inch slide length suits standard base cabinet drawers — pots and pans, utensil, and deep pantry-style pulls where the drawer depth matches an 18 inch nominal length. Full extension means the back of the drawer comes fully out to the cabinet opening, so nothing gets buried. That matters in a deep base cabinet where a 3/4-extension slide would leave the last few inches of the drawer inside the box and out of reach. The integrated soft-close means no slap at the end of the close — a feature that holds up through years of daily kitchen use. Because this slide is rated for both face-frame and frameless construction, it covers the two most common cabinet types in residential and light-commercial work without needing a separate SKU for each.
The Dynapro slide is built from steel with a zinc finish, the standard corrosion-resistant finish for indoor cabinet slides. Roller bearings carry the drawer member through the travel — a system that delivers quiet, smooth movement across the full 18 inch extension. The slide accepts drawer sides from 1/2 inch up to 5/8 inch thick, so it works with a range of common drawer box materials. Build the drawer box to the Dynapro specification for the nominal length, including any rear notch and locking-device drilling the system requires — the undermount fit is engineered, and a box built to the wrong width or wrong side thickness will not seat correctly.
Cabinet shops running production kitchens and baths will find the Dynapro 18 inch a reliable workhorse for base cabinet drawers — full extension and soft-close are the two features most homeowners expect, and they are both built in. Designers specifying concealed hardware for frameless Euro-style boxes or traditional face-frame kitchens can use the same slide in both environments. Contractors doing installs and homeowners replacing worn-out slides both benefit from a straightforward undermount that conceals completely beneath the box and adjusts at the front locking devices after hanging. This slide is for indoor cabinetry; it is not rated for exterior or high-moisture environments.
The Dynapro is rated for both face-frame and frameless installations. In a face-frame cabinet, confirm whether your specific installation requires rear mounting support — face-frame depth and frame setback vary, and some configurations need rear brackets to carry the back of the slide. Rear mounting brackets for the Dynapro are sold separately.
This slide is designed for drawer sides from 1/2 inch to 5/8 inch thick. The maximum is 5/8 inch (approximately 16mm). If your drawer box uses 3/4 inch sides, this version is not the right fit — Dynapro offers other versions matched to 3/4 inch stock.
The soft-close mechanism is integrated into the Dynapro slide. Adjustment specifics depend on the locking device and front fixing used with the slide — consult the Grass Dynapro installation documentation for closing-force settings available on your configuration.
Verify the sold-as unit on the product listing before ordering. Undermount slides for a single drawer require one left-hand and one right-hand runner, and pricing and packaging vary by SKU. The 100 lb load rating stated here is per pair.
Front locking devices for Dynapro undermount slides are typically sold separately. They are Dynapro-specific — locking devices from other brands or other Grass series are not compatible. Order the matching Dynapro front locking devices alongside the slides to complete the installation.
Full extension, soft-close, and a 100 lb rating in a slide that disappears beneath the drawer — the Dynapro 18 inch delivers the performance residential and light-commercial cabinetry demands, in both face-frame and frameless construction.
