Yes. Just screw the SPIN-DIGGER into the soil up to the base (where the screw tip meets the post), and you’re at the right height for mail delivery.
Yes. Just unscrew the SPIN-DIGGER.
The difference between a normal post and a SPIN-DIGGER Screw-Post is like the difference between a nail and a screw. A nail can be easily pulled out, while the threading on a screw secures it into a material. When you dig a hole to install a post, you break up the soil, which softens it. Screwing a post into the soil doesn’t void the soil, but actually compacts it as the soil moves away from the auger. With this displacement process, you don’t get frost heaves. The standard hole dug for a mailbox post is 6 inches, with about 2 inches of concrete poured into the softened soil. It simply doesn’t have the same strength as a post that is screwed into the ground. This type of ground screw technology has been tested and approved for construction for over a decade.
Post installation takes about 10 minutes from start to finish. And you don’t need to exert a lot of strength. Just stand the SPIN-DIGGER upright, in position, and start turning. It’s really that easy!
Absolutely! We use 16-gauge, rust-resistant aluminum, which is 1/8” thick—twice as dense as a normal post. We also striate (rib) the metal to increase the strength. Plus, unlike wood, this heavy-duty aluminum doesn’t weather or rot.
The auger tip is engineered to cut through almost any soil, including clay and rocky soil. Add some water to the soil to soften it; install spin digger when it dries the soil will be hard again. The SPIN-DIGGER, however, is not designed to be installed in frozen ground, cement, or stone.
