Note: The HangPro™ Drywall Lift is designed for wall heights not to exceed 10 feet. The top of a 4 foot sheet will hang up to a 10 foot ceiling. The main frame has safety stops to prevent the accidental elevation of the carriage beyond the safety height limit of the column. While the HangPro™ Drywall Lift was designed for drywall panels, it can also handle plywood, OSB, siding, metal doors and wood panels. The HangPro™ Drywall Lift Model 100 can be folded in half for easier transportation.
