While weight is applied on the first step, wheels retract and the moon cups with cleanroom compatible plastic guards, sit firmly on the floor, ensuring a safe climb.

Disclaimer: These cleanroom step stools, although sold & used for over 20 years worldwide, do not have independent safety certification. This is due to the constraints on materials that are permitted in cleanrooms (ie no rubber). Individual cleanroom managers are required to authorize the step stools as fit for purpose.
