Hexagonal glass knob. The bolt is inserted from the front through the head of the knob. A perennial favorite since the late 19th century on furniture of all kinds and in the kitchen, bathroom and everywhere in the home. Comes with a 3" long smooth-headed nickel-plated bolt and nut, just as in the old days.
Note: This glass knob is durable. However, please bear in mind that it is made of glass, and that glass knobs and handles require special care during installation. No power tools - use only hand tools to install glass hardware.
