Grass America's Dynapro undermount drawer slide, known for its smooth running performance and quiet kinematics, utilizes an integrated rack and pinion system. This technology allows the slides to move in tandem with one another, improving glide, reducing noise, and preventing the drawer from binding when closing. Dynapro, rated for loads up to 132 lbs with its heavy-duty model, is suitable for drawer applications up to 48 in. wide, with no additional synchronization hardware required. Designed for 16mm - 19mm drawer material, the Dynapro’s hardware is fully concealed under the drawer box. The slide works with both face frame and frameless cabinetry and has an integrated rear cleat to secure the drawer box to the slide. The product comes in 9-in. to 30-in. lengths in increments of 3-in. and offers several different versions, including the standard, heavy-duty, and extended lengths.
