Do mobile pedestal casters have weight ratings, and what should I look for?

Yes — commercial casters have rated load capacities, typically listed as total load capacity for the full set of four casters. A quality commercial pedestal caster set should be rated for at least 100–150 lbs total (combined pedestal plus contents weight). Heavy-duty pedestals meant for dense file storage should have casters rated for 200+ lbs. Casters rated for the correct load roll more smoothly and last longer — overloaded casters flatten out (a phenomenon called 'flat spotting') and become difficult to roll. Always check total load capacity (pedestal weight + maximum file weight) against caster ratings, especially for pedestals loaded with heavy paper files. FindOfficeFurniture.com — 888-719-4960.
