Concealed Soft-Close Undermount Slide For Compact and Small-Box Drawers

The Grass Dynapro 12 inch undermount drawer slide is a full-extension, soft-close concealed runner rated 100 lb per pair, built for drawer boxes with 1/2 to 5/8 inch sides in face-frame and frameless cabinets. At this shorter length it suits bathroom vanity drawers, spice pull-outs, shallow base cabinets, and any application where a standard 18 or 21 inch slide runs too long for the cabinet depth.

Key Features

• Full extension brings the entire 12 inch drawer box out to the cabinet face, so nothing at the back stays hidden.
• Integrated soft-close catches the drawer near the end of travel and settles it shut without slamming.
• 100 lb capacity per pair handles loaded small drawers with margin to spare.
• Dynapro synchronization keeps both slides of the pair moving in unison, eliminating racking and shimmy even on short travel.
• Fits face-frame and frameless cabinets so the same slide works across both construction types.
• Roller-bearing carriage on steel members with a zinc finish delivers smooth, quiet travel through years of daily use.

Where the 12 Inch Length Earns Its Place

Shorter drawer lengths create their own set of challenges: a slide that is even slightly too long will not fit the cabinet's interior depth, and a slide that is too short wastes drawer capacity. The 12 inch Dynapro is sized for cabinets with a shallow interior — bathroom vanity banks, upper spice cabinets, bedside nightstand drawers, and utility boxes built into furniture pieces. Full extension at this length means the back of a narrow drawer opens fully to the cabinet face, which matters more in a compact space than in a deep kitchen base. Wherever a full-size slide would be overkill on depth but a cheap roller slide would underdeliver on motion quality, this is the right choice.

Steel, Zinc, and Roller Bearings Built to Last

The Dynapro runner is steel throughout, with a zinc finish that protects the members through indoor service. Roller bearings keep the carriage smooth and quiet under load, and because the slide rides completely beneath the drawer box, no hardware is visible when the drawer is open. The 100 lb per pair rating and Dynapro's synchronized movement come from the same platform used in full-length kitchen installations — the 12 inch version does not trade performance for size.

Who This Slide Is For

Cabinet shops running bathroom vanity lines, furniture builders adding concealed storage to nightstands or built-ins, and contractors finishing out shallow utility cabinets will all find the 12 inch Dynapro the practical answer where longer slides simply do not fit. It is equally at home in face-frame and frameless construction, which means one slide family covers the whole shop's output. Designers specifying handle-less fronts should note that this SKU is the soft-close version; a push-to-open or Tipmatic Soft-close model is a separate selection within the Dynapro line if a handle-less front is required.

The Right Slide, Matched to the Job

Choose the 12 inch Dynapro when the cabinet depth calls for a shorter runner but the job still demands full extension, soft-close performance, and the reliability of a synchronized concealed slide.
