I love these production videos some manufacturers put out. It’s always cool to see how stuff is made, and this is the first video I’ve seen on a roll cab.
Mac offers 3 levels of boxes, the Select Series, Tech Series, and the top tier Macsimizer™. This video shows the production of what looks to be a Tech Series MB1000A, presumably at their Georgetown, OH production facility. The Tech Series gets you a heftily constructed box with heavy duty ball bearing slides, 1,200 lb. casters, adjustable detents, and up to 90,000 cubic inches of storage.
It’s certainly nice to see things like this still made here in America. Check it out:
