The precast concrete head is installed at the ground surface, and steel bearing pins are driven through the head and into the ground using simple hand-held tools. This is the best way to install a reliable and durable foundation that will last the lifetime of your deck structure. Minimal digging required, Limited Lifetime Warranty. Proudly made in the USA. New offset style, accepts 4x4, 4x6 & 6x6 deck support posts. Can be installed using a large sledge hammer or the custom driver tool. Doing a single project? There is no need to purchase the custom driver tool, Many standard pointed bits that fit 30# - 60# Electric Hammer tools will easy slide inside the pins closely enough to speed up installation.
