The World's Strongest Hand-powered Heavy Dute Metal Roller!

This is our strongest roller yet, rolling half inch thick bar steel! As I say in the intro, we're claiming this is the world's strongest hand-powered metal roller. If you know of anyone making and selling something better, please let me know! We make a 10 gauge unit, with 2 inch rollers, a Super strong 4 inch roller machine, and this unit which has 6 inch diameter rollers.
