Mini Pipe Calipers are unique outside diameter calipers created and manufactured by Oregon Rule Co. The Mini Pipe Caliper is a tool often useful to Engineers, Draftsmen, Pipe-fitters, Contractors, Carpenters, Plumbers, and related industries. This is a fractional measuring unit, which reads in inches. This Mini Pipe Caliper can measure up to 6" in diameter and pipe sizes up to 5" in diameter. A conversion chart printed on the caliper translates measurements of the outside diameter to the nominal interior diameter dimension. The swing arm can extend into a 7" long ruler.
