I purchased way more than I ended up needing for our house. I have 4, total, available for sale. Two have the hardware to install, with screws cut to 3/4 of an inch. Two do not have the hardware to install. Beautiful, vintage-looking glass knobs. From the Pottery Barn Website (note that these are no longer available): Beautiful hardware can do wonders for a room, bringing character to the most unexpected places. Our exclusive collection features hand forging and casting techniques that have evolved over centuries, original molds carved by master woodworkers, and finishes painted or hand rubbed one at a time. The graceful curves and bright finish of our Vintage Glass pieces evoke the fixtures found in 20th-century Parisian hotels. Cast iron with a nickel-plated finish; molded glass. Nickel finished knob has the straight base. Polished Nickel, Satin Nickel and Bronze finished knobs have a decorative base. Mounting hardware includes screws (note that for the two knobs that have mounting hardware, that screws have been cut to 3/4" length). Imported. Knob: 1.25" diameter, 1.5" deep Weight Capacity: 15 pounds Wipe with a soft, dry cloth.
