Amerock Blackrock 1-5/16 inch knob is a round cabinet knob from the Blackrock collection that provides a defined hand grip, which matters when you want consistent pull feel on cabinet doors and drawers across a project. The 1-5/16 inch, or 33 mm, diameter creates a comfortable contact area, which helps when users are opening larger fronts or heavier drawers many times a day. This knob is part of Amerock decorative cabinet hardware, so it serves as a visible finishing detail on residential or commercial cabinetry where appearance and function work together.

The knob is identified by Amerock part number BP55270BBR, which supports consistent reordering on repeat jobs or when matching existing Blackrock installations.
