The APEX 120TPN is an Artisan series diameter tape designed for measuring the outside diameter or circumference of cylindrical objects such as pipes, tanks, and round stock. The blade is 20 feet long and 0.375 inches wide, constructed from steel with a Nubian blade finish that provides contrast for clear reading in the field. The B10 blade style is formatted for SAE measurements. This tool is used by plumbers, pipefitters, mechanical contractors, and industrial maintenance technicians who need accurate diameter readings without calculation.
The 120TPN fits residential and commercial trade applications where pipe sizing, tank measurement, or round-stock dimensioning is part of the workflow. Its compact case — 3.8 inches long, 3.4 inches wide, and 1.2 inches tall — makes it easy to carry on a service belt or in a tool bag. The brown case and Nubian blade finish are characteristic of the Artisan product family from APEX. SAE graduation makes it compatible with standard inch-based pipe sizing used in North American plumbing and mechanical work.
Designed for general-purpose diameter and circumference measurement of cylindrical objects in plumbing, pipefitting, and mechanical trade applications using SAE inch-based measurements.
No installation is required for this measuring tool. Ensure the blade is fully seated and the tape is routed correctly around the workpiece before taking a reading. Keep the blade clean and free of debris to maintain accurate measurements. Store the tape retracted to protect the blade edge and finish.
