Established in 1903 by Adele V. Holman and partnered with Danish cabinetmaker Hans Jorgensen to create the Jorgensen wooden handscrew.

The product line was expanded to include C-clamps, bar clamps, and the famous Pony pipe clamps.

The product line also included miter boxes and saws, wood and metal working vises, and a drill powered wood working lathe.

In 2016 the company closed and was subsequently purchased by GreatStar Industrial (based in China).
