A one-piece roll guard (10) having two half segments (12, 14) connected by an integral hinge (16) for protecting a caster (100) wheel by clearing obstacles away from its rolling path. The two segments of the roll guard (10) are closed and secured together around the caster wheel with a locking tab (18a) and matching locking slot (18b) integrally formed in the two segments. The roll guard is formed with a weighted lower lip (26) to improve stability by lowering the center of gravity of the roll guard (10).
