Apex 120PN Artisan Diameter Tape 20 Ft Steel Sae

Product Description

The APEX 120PN is a diameter tape measure from the Artisan line, designed for direct diameter and circumference measurement on cylindrical objects such as pipe, tubing, and round stock. The blade is 20 feet long, constructed from steel with a Nubian finish, and formatted in SAE units. At 0.375 inches wide, the B12-style blade delivers consistent contact along curved surfaces. The case measures 3.9 inches in length, 3.4 inches in width, and 1.2 inches in height, making it a compact tool for field and shop use. Pipefitters, plumbers, and mechanical tradespeople use diameter tapes when direct outside diameter measurement is needed without calipers or wrap-and-calculate methods.

The 120PN suits applications where outside diameter readings must be taken quickly on round workpieces in the field. Typical use cases include pipe sizing verification during plumbing and mechanical installations, mill and fabrication work on round bar or tubing, and any situation where standard linear tapes are insufficient for accurate diameter measurement. The SAE scale makes it compatible with standard inch-based trade work in North American installations. No auto-lock mechanism is present, so the blade is managed manually during measurement.

Key Features

• 20-foot steel blade for measuring large-diameter cylindrical workpieces
• Nubian blade finish for contrast and readability on metal surfaces
• B12 blade style at 0.375 inches wide for consistent contact on curved surfaces
• SAE graduation for standard inch-based measurement
• Compact case at 3.9 x 3.4 x 1.2 inches for easy tool belt or bag storage
• No auto-lock — manual blade control for deliberate, repeatable reads

Compatibility

Designed as an OEM-style replacement or direct-use diameter tape for trade professionals requiring SAE-graduated circumference-to-diameter measurement on cylindrical pipe, tubing, or round stock.

Installation Notes

No installation is required for this hand tool. Ensure the blade lies flat against the full circumference of the workpiece for an accurate diameter reading. Keep the blade clean and free of debris that could cause misreads or premature wear. Store the tape retracted to protect the blade finish and scale markings.
