For a rigid caster, change the “S” to “R” in the model number. For example, “47-UPB-0520-R.” To order rig only, omit the blue letters. For example, “47-0520-S.” For approximate weight of a rigid caster, deduct .7 pounds. Dimensions shown are nominal. If precise dimensions are required, please consult your RWM representative.
