The Stop Bracket Pair by Tie Down Roofing is a necessary component for the TranzVolt Ladder Hoist. The Stop Bracket Pair with Hardware comes complete with all the hardware required for installation. This product stops the carriage system from descending below the bottom rungs of the track. The development of the TranzVolt began when several companies approached Tie Down, looking for a more efficient and effective platform hoist kit. Tie Down worked directly with these companies to identify solutions for multiple industries. The TranzVolt Platform hoist lift saves time in setup and operation, allowing contractors better efficiency when installing solar panels and lifting more materials. Tie Down Safety maintains high standards and quality control through quality raw materials and components made in the USA.
