Irwin has released a new line of levels, dubbed the 2500 Series and they are marketing them in an unusual way. To demonstrate how tough they are, the company took a Chevy Silverado with 3,360 pounds of front axle weight and drove it across both a pair of Stabila Type 196 levels and a pair of their new 2500 Series levels. The Stabila levels folded under the pressure, but the 2500s held firm with just a slight bow in the middle. It’s an impressive demo and now perhaps you can use your levels to square up your shed and then make a ramp to drive your tractor into it… or not. In either case, the frame of the new levels are made with thick-walled high-grade aluminum. It’s gotta be pretty thick indeed to stand up to that type of stress.
