Hy! We use the wass 2 alignement and scafolding system. Its an all aluminum, one man system for install, alignement. Wheighs next to nothing compared to giraffe and other systems on the market. We've purchased 10 footers for optimum compatibility to varying heights of wall but the last time I talked with the rep. I believe they also have 8' & 12'. Just love it and would'nt go back to any other turnbuckle bs. Let me know what you think. I believe a google search will guide you in the right direction if not let me know and I'll try and dig up their info.
