This is the left-hand cabinet member of the Grass Dynapro concealed undermount system in the 18 inch length. It is a full-extension, soft-close runner rated 100 lb per pair, engineered for drawer boxes with 1/2 to 5/8 inch sides, and sold as a bulk single for production shops that stock each hand separately.
Dynapro is built for production residential cabinetry and premium custom work where concealed slides and synchronized movement matter. The 18 inch length covers standard base-cabinet drawers and most bathroom vanity applications. Because synchronization is built into each slide rather than added with a rod, there is nothing extra to source or install on wide drawers — the pair simply tracks together from the start. Dynapro is also the runner behind the Grass Vionaro drawer system, so shops already running Vionaro boxes will find this slide familiar in both fit and installation sequence.
This slide mounts in face-frame and frameless cabinets. In frameless work the cabinet member fastens directly to the side panel on the system hole pattern. In face-frame cabinets, the rear end of the slide needs support from Dynapro-specific rear mounting brackets — those brackets are sold separately and are specific to the Dynapro series. Do not substitute brackets from another slide line.
The Dynapro slide is steel with a zinc finish — a functional, corrosion-resistant surface suited to dry indoor installations. The roller bearing carriage runs quietly under load and contributes to the smooth, even feel that distinguishes this runner from economy alternatives. Because the slide is fully concealed beneath the drawer box, finish appearance is secondary to fit and durability.
Cabinet shops pulling from inventory are the primary buyer for bulk singles. Stocking left-hand and right-hand members separately by the case keeps the line moving without waiting on paired-unit orders. Designers and installers specifying Dynapro by the project will want to confirm the matching right-hand 18 inch member is in the same order — two left-hand members do not make a working set. Locking devices are Dynapro-specific and are not included with the bulk slide; confirm whether locking devices and rear brackets are on the pick list before the order ships.
No. This is the left-hand cabinet member only. A working drawer requires one left-hand and one right-hand 18 inch Dynapro slide. Order both hands to complete the set.
The box must be built to the Grass Dynapro specification for the 18 inch nominal length: drawer sides from 1/2 inch to 5/8 inch thick, the correct box width for the slide's clearance, a bottom recess, and a rear notch with drilling for the Dynapro locking devices. An off-spec or unmodified box will not seat correctly on the runners.
Locking devices are not confirmed as included with this bulk single. Dynapro front locking devices are series-specific — they do not interchange with other brands or slide lines. Verify the locking devices are on your order before you build the boxes.
Yes. Face-frame installs require Dynapro rear mounting brackets to support the back of the slide behind the frame. These brackets are sold separately and must come from the Dynapro series — brackets from other systems will not fit correctly.
The 100 lb rating is per pair, stated as a dynamic (cycling) capacity. It covers loaded kitchen drawers, deep vanity drawers, and most standard residential applications. Rate the full contents of the closed drawer — not just the heaviest single item — against this number.
Stock the left-hand member alongside its right-hand counterpart, add the Dynapro locking devices and any rear brackets your cabinet construction requires, and this slide delivers synchronized, full-extension movement on every drawer it carries.
