Grass has upgraded the Undermount Dynamic NT Full Extension Slides to their new Dynapro Undermount Drawer Slides. Like the other ones, these mount completely out of sight under the drawer, so the drawer looks like it glides on air. When about 3/4 closed, a hidden hydraulic actuator within the drawer slide gently pulls the drawer the rest of the way closed. A Soft-Close damper cushions the final movement so there is no “bang” or “thump.” Drawer removal is easy, too: simply grasp the green levers under the drawer, squeeze and lift. To reinstall it, slip the drawer back onto the slides and push it closed – spring-loaded catches automatically engage the slides. With a complete selection of mounting holes on standard 32mm centers, Grass Dynapro Slides fasten directly to the cabinet walls (5/8" min.) of Euro style cabinetry. For use in face-frame cabinets, use the Face Frame mounting bracket (order separately as “each”). The slides have an 88-lb. dynamic load rating with a 100-lb. static load rating. Use either #6 x 5/8" flat head screws (0605-FPN) or Euro Mounting screws to attach the slides, but flat head screws only for the mounting bracket. Drawer Slides and Locking Brackets are sold in boxes of five pair. The Face Frame mounting brackets are sold as “each,” and two per drawer are required (i.e., 10 brackets per five pair of drawer slides). Screws are not included; six are required for each drawer slide and four are required for each bracket. Please specify length from drop down above.
