The Grass DynaPro 16 HD by Hafele is a Heavy Duty slide, designed to support up to 110 lbs. With 3D adjustment built in, you can tweak the slides’ height, side clearance, and tilt on the fly, ensuring your drawer faces will line up as perfectly as you need. Progressive movement and a Continious Self Locking mechanism allows these slides to more smoothly extend and retract, while a soft close system slows down your drawer while closing to prevent slamming.
