Low Profile Casters - Heavy Duty The casters with low profile are called machine caster wheels. Although the low profile casters serve as an accessory to equipment, they play an important part in the overall equipment, because the casters with a low center of gravity are able to stand in areas with a high load for a prolonged time and keep the equipment at a lower level and easily moveable. In our Enterprises these are the same traits we strive to achieve every day.
