The APEX C120TPN is an Artisan series diameter tape designed for accurate outside-diameter measurements on cylindrical objects such as pipe, conduit, and round stock. The 20-foot steel blade is finished in a Nubian/Chrome Clad coating that resists corrosion and maintains legibility under field conditions. The blade is 0.375 inches wide and reads in SAE increments, converting circumference directly to diameter so technicians can eliminate the manual calculation step. The B10 blade style is suited for professional use by plumbers, pipefitters, mechanical contractors, and industrial maintenance trades who need reliable diameter readings without a separate conversion chart.
This diameter tape is used wherever accurate pipe or cylindrical stock measurement is required in the field or shop. Common applications include plumbing rough-in, HVAC pipe sizing, industrial piping layout, and maintenance inspection of round components. The SAE measurement format makes it compatible with standard U.S. trade work. The compact case dimensions of 3.75 inches long by 3.75 inches wide by 1 inch tall allow the tape to fit in a tool pouch or service bag without bulk.
Designed as a professional-grade diameter tape for use on pipe, conduit, and cylindrical round stock in plumbing, HVAC, pipefitting, and industrial maintenance applications where SAE outside-diameter measurement is required.
Diameter tapes require no installation and do not involve electrical, gas, or pressurized systems. Wrap the blade snugly around the outside of the cylindrical object, keeping it perpendicular to the axis of the pipe or stock for an accurate reading. Avoid kinking or creasing the steel blade, as deformation will reduce measurement accuracy. Store the tape retracted to protect the blade edge and coating.
