This 15 inch Grass Dynapro undermount drawer slide is designed for drawer boxes with 5/8 to 3/4 inch sides — the thicker side-thickness version of the Dynapro line, offering full extension, integrated soft-close, and a 100 lb capacity per pair in a fully concealed runner.
The 15 inch length is the right call for shallower base cabinets and upper drawer banks where a longer slide would crowd the cabinet interior. At full extension, the whole box comes out to the face, so nothing stays hidden in the back of a spice drawer, a bathroom vanity, or a shallow utility pull-out. The 100 lb per pair rating covers these applications comfortably, even when the drawer is fully loaded.
Because this version is built for 5/8 to 3/4 inch drawer sides, it matches shops that build from 3/4 inch plywood or thicker hardwood stock. If your box uses 1/2 to 5/8 inch material, this is not the version to order — that side-thickness range takes a separate Dynapro model.
The Dynapro runner is steel with a zinc finish and a roller-bearing carriage. Because the slide mounts beneath the drawer box, it stays hidden when the drawer is open — no visible hardware on the sides, just wood. The integrated soft-close mechanism is part of the slide body, not a separate add-on, so the damping is consistent and there are no extra parts to install or replace.
Dynapro's built-in design also includes synchronization that keeps both sides of a drawer pair tracking together — useful for drawers up to 48 inches wide — without requiring a separate synchronization rod.
Cabinet shops building in 3/4 inch plywood or solid hardwood reach for this version when the box spec calls for thicker sides and a concealed runner with a clean close. It suits residential kitchen and bath work, furniture-grade cabinetry, and any project where the drawer front is the only thing visible and the slides need to disappear. Designers and contractors specifying handle-less fronts will find the soft-close a standard expectation at this price point; the Dynapro delivers it reliably without a separate mechanism to coordinate.
The two models are engineered around different drawer side thicknesses. This version is built for 5/8 to 3/4 inch material — the slide spacing, locking device seating, and box-width formula all reflect the thicker side. A 1/2 to 5/8 inch box will not seat correctly on this version; order the matching 16mm model for thinner material.
Dynapro front locking devices are series-specific accessories. Confirm whether this SKU ships with locking devices before ordering, and note that Dynapro clips are not interchangeable with other brands or undermount series.
In face-frame construction, the back of the slide needs rear mounting brackets behind the frame. Use Dynapro-specific rear brackets — those from other brands and series do not fit. Build the drawer box to the Grass specification for this length, including the rear notch and the drilling pattern for the locking devices.
Per pair, as is standard for all undermount slide ratings in this catalog. A typical kitchen drawer loaded with pots or dishes is well within that range.
Yes. Undermount slides require the drawer box to be built to the slide's nominal length. Build the box to Grass's published 15 inch specification — including the correct width formula, bottom recess, and rear notch — and the fit will be precise. An off-spec box length will not seat properly on the slides.
For shops and installers building with 3/4 inch drawer sides, this 15 inch Dynapro delivers the full-extension access, soft-close close, and concealed profile the job calls for — matched to the material you are already cutting.
