Tool facilitates hole layout on flanges, base plates

A tool for laying out holes on flanges and base plates is available from J&B Specialty Tools. The single tool allows the user to locate holes based on the web centerline, regardless of variations in flange width, without having to use a collection of squares to first mark horizontal and vertical lines.

The scale can be purchased separately and is designed to fit most combination square bodies. It also is available with its own hardened steel combination square body. It handles gauges up to 8 in. wide.
