These 2'' diameter knobs feature simple styling, sturdy construction and a low profile. They are available in two finishes—stainless steel and satin black—both of which are perfectly matched to the finishes on our I-Semble Rolling Barn Door Hardware Kits (#56667 and #52109, sold separately). With a projection of only 1/2'', they can also be used with our Bypass Rolling Barn Door Hardware Kit (#56591, sold separately) without the knob getting in the way.
