The 400 foundation is 6-sided and has a footprint of 11.5’ in diameter. Typically the 400 can be assembled in 6 hours by a two person crew and supports a base moment of 86,000 foot lbs with an average soil bearing capacity – 4,000 psf.
We’ve got two great designs to choose from. The first is our classic design, which features a central hub that all the truss arms attach to. This is perfect for situations where you need to keep the weight of each component as low as possible. On the other hand, we also offer a second design that uses three rings as a central hub, so that no single component weighs more than 110 pounds. This option is great for those who need a bit more versatility in their truss system. Whether you choose our classic or ring design, we’re confident that you’ll be impressed with the strength and durability of our products.
