Iron Swivel Casters Bar Knobs

Industrial-strength bar knobs can be tightened by hand and further secured by inserting a bar between the four prongs for leverage in heavy clamping applications.

These bar knobs are constructed of malleable iron and available in blank, reamed, or tapped styles. They are ideally used in areas where high pressure is needed and a lever or other clamping device doesn’t fit.

We carry bar knobs in 3/4 inch and 7/8 inch sizes. Find out if bar knobs are right for your application by reading about other knob materials and applications in our knowledge center.
