YH Collection handlesets are crafted of solid brass and polished to a gleaming luster. They make a significant first impression to any home. Our split-hub low torque mechanism allows the thumb-piece to work independently of the interior knob or lever for smooth and easy one-hand retraction of the latch bolt. YH Collection handlesets are fully compatible with all of our YH Collection and New Traditions® interior knob and lever designs offering total flexibility for interior selections.
