The Grass Dynapro 9 inch undermount slide is a compact, fully concealed runner built for drawer boxes with 5/8 inch to 3/4 inch sides — a side-thickness range that covers thicker hardwood and plywood boxes often used in smaller, high-quality drawers. It delivers full extension, integrated soft-close, and a 100 lb per pair capacity, all in a slide sized for spice drawers, jewelry inserts, and small base-cabinet pulls.
A 9 inch undermount is a specialized length, and its ideal home is any small drawer where concealed hardware and full rear access matter. Spice pull-outs tucked beside a range, shallow jewelry drawers in a bedroom vanity, small organizational inserts in a bathroom cabinet, and compact drawers in media or display cabinetry are all natural fits. The 5/8 to 3/4 inch side-thickness window adds further specificity: this is the slide to reach for when the box is built from thicker material than a standard dovetailed shop box. A shop building small drawers from solid 3/4 inch hardwood sides — where the thinner 16mm version would not seat correctly — can run the Dynapro in this thickness class without compromising the concealed look or the full-extension travel.
The Dynapro runner is built from steel with a zinc finish — a functional, corrosion-resistant surface well suited to the indoor environments where undermount slides spend their lives. Because the slide mounts beneath the box and stays hidden when the drawer is open, the finish is about protection and longevity rather than visual match. The roller-bearing carriage keeps movement smooth and quiet under load, and the integrated soft-close mechanism requires no adjustment out of the box. Dynapro slides are engineered with built-in synchronization across the pair, so both sides of the drawer track together on wider pulls — a benefit that holds even at this compact 9 inch length.
Cabinet shops building small drawers from 3/4 inch solid wood sides will find this the right Dynapro version where the standard 5/8 inch model would not fit. Designers specifying premium hardware for compact vanity or jewelry drawers get full-extension access and a silent close in a package sized to the drawer. Contractors finishing out face-frame kitchens with thick-sided spice inserts can run this slide in either cabinet construction with the appropriate rear mounting bracket. This is not the slide for a shop running standard 1/2 to 5/8 inch boxes at scale — that side-thickness range has its own Dynapro variant.
No. Slide length and drawer travel are separate specs. This is a full-extension slide, so the drawer member extends approximately the full nominal length — the entire 9 inch box comes out to the cabinet face.
Undermount slides are engineered around a specific side-thickness range. The spacing, locking-device fit, and box-width formula are all built to that dimension. A box built from 3/4 inch sides will not seat correctly on the 1/2 to 5/8 inch version of the Dynapro — this is the model that accommodates the thicker material.
Yes. The Cabinet Type attribute confirms face-frame and frameless compatibility. In face-frame installations, the rear of the slide needs support from Dynapro rear mounting brackets, sold separately. Those brackets are Dynapro-specific and do not interchange with other brands or series.
Dynapro front locking devices are series-specific accessories. Confirm whether they ship with this SKU or need to be ordered separately before placing a production run.
No. The drawer box must be built to Grass's published specification for this Dynapro version — nominal 9 inch length, the correct box width for the required side clearance, proper bottom recess, rear notch, and the drilling for the Dynapro locking devices. An off-spec box will not seat and run correctly.
When the drawer is small, the sides are thick, and the look needs to stay clean, this 9 inch Dynapro puts full-extension travel and a silent close behind a concealed runner built for exactly that combination.
