These GoJak® models are customer returns or trade show units that go through a thorough inspection to ensure all units are in good working condition. Any components that are not functioning properly are replaced with new parts.
These units will likely show some signs of use such as scratches in paint or marks where lock nuts had been tightened down on caster stem.
They are factory certified to be 100% in working order.
GoJak G6200 was replaced by the G6313. The only difference is the color of the bearing seal on the casters. It was changed from black to fuchsia.
