The Grass DynaPro 16 by Hafele is a family of drawer slides designed with either liquid or gas pistons for undeniably smooth motion. With depth and height adjustment standard, and 3D tilt adjustment optional, you can count on these slides to tolerate small errors in mounting and measuring. Fully Synchronized Runners add Progressive Movement to these slides, making them open and close more fluidly than telescopic drawer slides. A continuous self locking mechanism allows you to fully open your drawer then close it, with the slides locking the drawer in that position with out opening back out. These slides are friction disconnect models, meaning you don’t have to worry about levers or latches to disconnect and reconnect your drawer box to your cabinetry.
