When buying antique glass knobs it is like buying cloth, carpet, or having paint custom mixed, color may vary slightly from one shipment to the next. Or, glass pulls will not be an exact match with glass knobs. Look at some antiques with glass pulls and glass knobs and you will see that this is the way it has always been, an art, not a science.
Please note this measurement information:
The bolt that comes standard with these antique glass knobs extends beyond the back of the knob
- 1-5/8" on a 1" knob
- 1-3/8" on a 1-1/4" knob
- 1-1/16" on a 1-1/2" knob
- 1-7/16" on a barrel glass knob
A 2" bolt is available near the bottom of the page, often used with the smaller knobs, in order to have less bolt protruding out the back.
