This is the left-hand cabinet member of the Grass Dynapro undermount drawer slide, sized for 18-inch drawer boxes. It mounts beneath the drawer box on the left side of the cabinet, keeping the hardware fully concealed when the drawer is open. Order the matching right-hand member alongside this piece to complete one working drawer.
The 18-inch slide length suits kitchen base cabinet drawers, bathroom vanity drawers, and furniture pieces where the cabinet interior runs approximately 18 inches deep. Because the Dynapro runner mounts completely below the drawer box, the drawer sides stay clean and the interior is fully accessible at open. This format is common in production shops building frameless kitchen cabinets or transitional furniture lines, where concealed hardware is part of the design specification from the start. The bulk-pack quantity supports shops running multiple kitchens at a time — pulling from a single carton rather than ordering per drawer keeps the line moving.
The Dynapro cabinet member is formed steel with a zinc finish. Zinc electroplating protects the slide through the normal humidity and temperature variation of a residential or light-commercial interior. The undermount form factor keeps the runner out of sight and out of the way of the drawer box contents, so the only thing visible when a drawer opens is the drawer itself. Because this is the cabinet member — the part that fastens to the cabinet side — the drawer box attaches at the front through Dynapro front locking devices, which are ordered separately and are Dynapro-specific.
Cabinet shops running Dynapro systems at production volume are the core buyer for this SKU. The 364-unit bulk pack is built for that context: a shop building a run of 18-inch base drawers pulls this carton rather than piecing together quantities from smaller packs. Designers and contractors specifying Dynapro for a single project can also pull from this SKU, though the bulk quantity favors shops with ongoing volume. Because this is a single-handed component, knowing your cabinet layout before ordering matters: each drawer needs one left-hand and one right-hand cabinet member, plus the appropriate drawer members and locking devices to complete the assembly.
One complete drawer requires the matching right-hand cabinet member, both drawer members (also handed), and a pair of Dynapro front locking devices. All components must be Dynapro-specific; they do not interchange with other undermount systems.
Yes. The drawer box must be built to the Dynapro specification for this slide length, including the correct box width, drawer side thickness, bottom recess, and the rear notch and locking-device drilling. Boxes built to a different spec or for a different slide brand will not seat correctly on Dynapro runners.
Dynapro runners are available in versions for different drawer side thicknesses. Confirm your drawer side thickness — commonly 5/8 inch (16mm) or 3/4 inch (19mm) — and match the slide version before ordering. This listing should be verified against the Grass specification to confirm the side thickness it serves.
Yes. The Dynapro platform supports Grass's Tipmatic Soft-close system (combined push-to-open and soft-close) as well as standard soft-close front locking devices. Those are separate components ordered by the motion feature you want; confirm Dynapro compatibility for each accessory before ordering.
Dynapro runners install in both frameless and face-frame cabinets. In face-frame applications, rear mounting brackets are typically required to support the back end of the runner — confirm the bracket requirement and order the appropriate Dynapro rear hardware before building.
When your layout calls for 18-inch concealed runners and you're building in volume, this left-hand cabinet member in bulk-pack quantity keeps the job supplied and the drawer line moving without interruption.
