The photos do not do these justice! The jacks arrived today, and I am extremely satisfied with their overall quality and construction. Despite being very heavy duty in build quality, the aluminum is extremely lightweight. They adjust flat quickly for transport and are fully adjustable for inside or outside ladder deployment. No further assembly or disassembly is required.The other best feature is an adjustable plank stop that you cannot see in their advertising photos. It is included and will allow you to secure your plank firmly, so there is no slippage, depending on width of plank.Nice job TITAN! I am very pleased with your product and it should last for years of safe usage.
