The newest addition to the Unifab Caster line is the directional locking wheel. By locking the caster so it does not pivot, the rack or cart can be pulled through hallways without worrying about the opposite end swinging out. So instead of needing two people to transport a cart, only one person is needed. Moreover, the risk of damaging walls and surrounding equipment is reduced.
Unifab casters come with durable poly wheels, with the newest version being a double-wheeled caster that allows the unit to roll easier on varied surfaces and track around corners more efficiently.
