Abstract
A caster has a horn of semi-circular configuration about an axle receiving apertured boss, a web extending radially outwardly from the boss to a semi-cylindrical flange and a pair of wheels, one on each side of the horn, the tread of the wheels being flush with the outer cylindrical surface of the flange. Hub shields are mounted on the wheels in such manner as to avoid load transmission to the shields, yet accommodating a variety of appearance features, ease of installation and reliable retention of the shields in place of the wheels.
