The standard medium-sized glass cabinet knob from the 1920s
and 1930s is 1 1/4″ across the top and stands from 1 1/8″ to
1 1/4″ tall. This one is an example of the hexagon style or
6-point style. Because glass knobs were made by different
companies, the knobs vary slightly. A smooth-headed bolt,
which goes through the glass knob, fastens the pull to the
cabinet. Bolts can be ordered elsewhere in the catalog.
