A clamp, and cable management system including the clamp, includes a bolster with a first clamping surface, and a keeper that is to be coupled to the bolster. The keeper is adjustable relative to the bolster to establish a first separation of the keeper from the first clamping surface of the bolster, and a second separation of the keeper from the first clamping surface of the bolster. The first separation is different from the second separation. The keeper includes a second clamping surface configured to cooperate with a first object having a first exterior dimension, and a third clamping surface, different from the second clamping surface, that is configured to cooperate with a second object having a second exterior dimension.
