Lufkin 120PN Steel Diameter Tape Measure 240 Inch

Product Description

The LUFKIN 120PN is a steel diameter tape measure designed for precision circumference and diameter measurement in trade and industrial applications. The tape extends to 240 inches and features 1/8 inch graduations, making it suitable for accurate layout and measurement work. At 3/8 inch wide and 0.008 inch thick, the blade is narrow and flexible enough to wrap around cylindrical objects such as pipe, conduit, tanks, and structural members. The tape is constructed from steel for durability in field conditions. This tool is used by pipefitters, plumbers, millwrights, and other trade professionals who need reliable diameter readings without a caliper or micrometer.

The 120PN is suited for applications where determining pipe diameter, tank circumference, or round stock dimensions is required on the job. Its 240 inch maximum measurement range accommodates large-diameter work including storage tanks, pressure vessels, large-bore pipe, and similar industrial or commercial infrastructure components. The compact blade profile allows the tape to seat flush against curved surfaces for consistent contact and repeatable readings.

Key Features

• 240 inch maximum measurement range for large-diameter applications
• 1/8 inch graduation spacing for clear, readable markings
• Steel blade construction for durability in field environments
• 3/8 inch wide blade wraps cleanly around cylindrical surfaces
• 0.008 inch blade thickness provides flexibility for tight-radius wrap
• No belt clip — compact form for toolbox or pouch storage

Compatibility

Designed as a general-purpose diameter tape for use in pipefitting, plumbing, millwright, and industrial maintenance applications where circumferential or diameter measurement of cylindrical objects is required.

Installation Notes

Diameter tapes require no installation. When taking measurements, ensure the tape lies flat and fully contacts the surface of the object being measured with no gaps or overlap at the reading point. Keep the blade clean and free of grease or debris to maintain accurate graduation readings. Store the tape coiled loosely to prevent blade kinking or set.
