This is the right-hand slide of Grass's Dynapro concealed undermount system in the 15 inch length — a full-extension, soft-close runner rated 100 lb per pair, sold as a bulk single for face-frame and frameless cabinets with drawer sides from 1/2 to 5/8 inch thick.
Shallow drawers present a real spec challenge: most premium undermounts start at 18 inches, leaving narrow spice pull-outs, small bath vanity drawers, and 16-inch-deep upper cabinets with limited options. At 15 inches, Dynapro covers those shorter runs without stepping down to a lesser slide. The 15 inch nominal length suits drawers built to match — island spice drawers, bathroom medicine-cabinet pull-outs, and any shallow box where a longer slide simply will not fit the cabinet interior. Full extension means nothing stays out of reach at the back of the box, and the 100 lb dynamic rating holds up to jars, bottles, and loaded organizer inserts.
The Dynapro runner is steel with a zinc finish — a functional, corrosion-resistant coating designed for years of indoor service. Roller bearings carry the drawer smoothly and quietly through the full length of travel. The integrated soft-close uses a liquid damper rather than a friction ramp, so the close is genuinely damped: no slam, no bounce, just a controlled, silent finish. Because the mechanism is built into the slide body, there is nothing separate to install, adjust, or replace. Synchronization is also built in, which keeps wide drawers from racking side to side — a useful feature even on 15 inch runs where the drawer box is relatively narrow.
Production cabinet shops reach for bulk Dynapro singles when they run mixed-length programs and want one undermount system across the whole shop. A 15 inch right-hand single is the complement to the left-hand member in the same length: stock equal quantities of each and pair them at the line. Custom shops specifying a premium concealed runner for a specific shallow application — a narrow bathroom vanity, a shallow spice bank, a small drawer in an island — will find the 15 inch length covers the spec cleanly. This slide works in face-frame and frameless cabinets; face-frame installs require Dynapro-specific rear mounting brackets, sold separately.
This SKU is the right-hand slide only. Add the matching left-hand 15 inch Dynapro slide for one pair. You will also need Dynapro-specific front locking devices (verify whether they are included with this bulk SKU or sold separately) and, for face-frame cabinets, the Dynapro rear mounting brackets.
Yes. Dynapro suits both face-frame and frameless construction. In a face-frame cabinet, the rear of the slide needs Dynapro-specific rear mounting brackets — these are not included and do not interchange with brackets from other undermount systems.
Drawer sides from 1/2 inch to 5/8 inch (12.7mm to 16mm). This is the standard 16mm version of the Dynapro. Build the drawer box to Grass's published specification for the Dynapro series — including the correct box width, bottom recess, rear notch, and locking-device drilling. An off-spec box will not seat correctly on the slides.
Per pair, as undermount load ratings are stated throughout this category. One right-hand and one left-hand slide working together carry 100 lb.
Dynapro front locking devices and brackets are Dynapro-specific and do not interchange with other undermount brands or series. Use Grass Dynapro accessories only.
A 15 inch soft-close, full-extension undermount at 100 lb per pair gives shallow drawers the same concealed, quiet, fully accessible experience as any full-depth installation — Dynapro just does it in a shorter run.
