The FastJack's proprietary design can simply be described as the most creative, powerful, and cost-effective tool of its kind. The FastJack has been laboratory tested to provide 2,359 pounds of strength using only a single lag bolt, thanks to its precision CNC machined base and stanchion, as well as strict engineering and material requirements (included).
The 4.5' standoff is for regular blinking installations (for composition & flat rooftops).
