CatStrap, based near Toledo, makes American-made anti-theft shields for catalytic converters and EV charging cables. Its patented, low-profile hardened-steel barriers have protected more than 100,000 vehicles over a decade, while its newer EV Cable Shield extends the same approach to public charging stations. The company also offers the Cateye 130-decibel alarm and DyeDefender blue-dye deterrent as add-ons.
