Constructed of heavy-duty aluminum, the Free Standing Mobile Access Platform from Flexible Lifeline is lightweight and mobile, and urethane wheels enable the platform to be positioned by one person. Through use of a hand-operated winch, the unit can be adjusted to varying heights. Tie-off points at the top of the platform provide 100% tie-off from the ground up.Flexible Lifeline Systems, www.flexiblelifeline.com, (800) 778-9048
