FMP MetalMaster Pro™ is a professional folding ruler designed specifically for insulation mechanics, sheet metal workers, and industrial fabricators.

This all-in-one tool combines a precision ruler, circumference scale, pipe size chart, and insulation layout reference into a single compact tool that fits easily in your pocket.

The front side features a direct circumference scale that allows measurements taken with a circumference tape to be transferred directly to the ruler without additional calculations. It also includes both 32nds and 16ths inch graduations for precise layout work and accurate measurements in the shop or in the field.

On the reverse side, the MetalMaster Pro includes a built-in Iron Pipe Size versus Insulation Thickness chart covering pipe sizes from 1/2" through 36" and insulation thicknesses from 1", 1-1/2", 2", 2-1/2", and 3". It also provides direct references for both insulated pipe dimensions and bare steel pipe dimensions, helping fabricators and insulators work faster and more accurately.

Designed by industry professionals, the MetalMaster Pro helps reduce layout time, eliminate measurement errors, and simplify fabrication and installation tasks.
