Steel and cast iron caster swivel wheels. These are very heavy duty. They swivel on ball bearings, so are smooth and strong, despite their age. These workhorses have been in use for decades and are still extremely strong! Four holes for fasteners to attach to whatever project your heart desires! As-is, unrefurbished.
Measurements: 3 inch diameter wheel x 1 1/8 inches wide, sits 3 5/8 inches tall.
These are not reproductions in weak modern metal from questionable sources, these are true vintage hardware.
Available individually, price per each.
