A bar or section of uniform cross section, preferably of aluminum alloy, is cut to required lengths to provide blanks which can be used as caster frames with a minimum of machining. The caster frame consists essentially of a first portion defining a hollow space extending vertically therethrough for rotatably receiving a connector rod or pin by which the caster is to be attached to a desired article, and a second portion for supporting the axle of a wheel or wheels. Numerous modifications are possible.
