Sometimes we discover a really good tool that just doesn’t seem to be available from our locksmith distributors. Our 4″ stainless steel electronic caliper is one of those tools. We couldn’t help notice that we usually only measure things less than 1″ and it really is kind of hard to carry around the 6″ dial caliper we use at the bench. Then we found this model. It will fit nicely into a shirt pocket and has a carrying case if you prefer that.


For those who need another 6″ bench caliper, our CAL6 (Dial) and CAL6E (Electronic) has the same stainless steel frame construction and is reasonably priced.  Email orders to
