This heavy duty set includes 4 industrial 8″ rigid cast iron caster wheels. They have roller bearings to ensure they roll very smoothly. The 5 spoke wheels are 2″ wide and are rated to 900 lbs each. They have a weathered patina on the steel which gives it a mid-century factory look, and the wheels are an aged matte black. Weight is 11 lbs each, and they are top plate mount. These ship out in 2-3 weeks.
I also have many other vintage caster models and sizes including rigid, swiveling, with locks, 4", 5", 6" and 8", and threaded mounting. You can contact me if you have questions, or are looking for something different. The 3rd picture is a group of other caster models I carry.
