The Grass Dynapro 2.0 is a 21-inch undermount drawer slide built for 5/8-inch (16mm) drawer sides, carrying loads up to 100 lb per pair with full extension and integrated soft-close. It stays hidden beneath the drawer box, leaving nothing but clean wood visible when the drawer is open.
A 21-inch slide matches a 21-inch nominal drawer length, making it the right choice for standard-depth kitchen base cabinets and tall bath vanities where the drawer runs close to the full interior depth. Full extension means a press toward the back of a pots-and-pans drawer or a deep utensil pull-out reaches all the way to the rear rather than stopping several inches short. Cabinet shops running production kitchens will find the 21-inch length covers the most common base-cabinet drawer depth, and the 100 lb rating keeps heavier storage drawers well within spec without stepping up to a heavy-duty line. Residential remodelers and designers specifying custom cabinetry get the same concealed look as premium European systems without surrendering load capacity.
The Dynapro 2.0 chassis is steel with a zinc finish, which keeps the slide protected in typical indoor cabinet environments. The roller bearing system is optimized for smooth, quiet movement under the loads this slide is rated for. Because the slide mounts beneath the drawer box and attaches at the front with locking devices, none of the mechanism is visible when the drawer is open — the clean, hardware-free look that undermount slides are chosen for. The integrated soft-close damper is part of the slide unit, so there is no separate damper component to source or install.
The Dynapro 2.0 is engineered for drawer sides in the 1/2-inch to 5/8-inch range, with 5/8 inch (16mm) as the maximum. Build the drawer box to the Grass Dynapro 2.0 specification for a 21-inch nominal length: that includes the correct box width formula, rear notch, and locking-device drilling. The slide suits both face-frame and frameless cabinet construction, though face-frame installs require rear mounting brackets sized for this series, ordered separately. Front locking devices, adjustment hardware, and any Tipmatic push-to-open components are Dynapro-specific and should not be substituted with parts from other undermount brands or series.
No. The maximum drawer side thickness for this version is 5/8 inch (16mm). Grass offers Dynapro 2.0 variants for 3/4-inch (19mm) sides — select the version that matches your drawer box material.
The drawer box should be built to the 21-inch nominal length per the Grass Dynapro 2.0 specification. Unlike side-mount slides, undermount systems require the box length to match the slide's nominal length for proper seating and locking.
Soft-close is built into the slide. No add-on damper is needed — the 21-inch Dynapro 2.0 ships with damped closing as part of the unit.
Yes. The Dynapro 2.0 is compatible with the Grass Tipmatic Soft-close system, which combines push-to-open with the slide's soft-close action. Tipmatic components are Dynapro-specific and must be ordered separately.
Yes. In face-frame construction the slide's rear end needs support from brackets rated for the Dynapro series. Those brackets are sold separately and are not interchangeable with other brands' rear hardware.
When the drawer box is 5/8-inch stock, the cabinet is 21 inches deep, and the application calls for full extension with a soft-close finish, the Dynapro 2.0 is the direct answer — no upgrading the load rating to get soft-close, no sourcing a separate damper to add it later.
