Built with HEAVY THICK METAL. I don't need to bolt it to the ground.
I mean this thing is QUALITY. Landmine slides in the Base perfectly. There is a Handle to carry it around (I store it behind my power rack). Frees up my power rack (don't need this attached landmine anymore). I inserted my 84" axle bar (also Titan brand) in it, and I have a world class setup :-)
Showed up only 4 days after ordering. Buy this and You will not regret.
