Adjustable Clamp

The Adjustable Clamp Company was incorporated in 1903, by Adele V Holman, to manufacture genuine Jorgensen Handscrews. Today 5 generations later great-great-grandson Douglas Holman is President of the company. Throughout the years each Holman has put his or her mark on the company.
In the 1920's and 1930's Adele's son Harry applied for and received patents on the JORGENSEN "C" Clamps, JORGENSEN Steel Bar Clamps, PONY "C" Clamps and PONY Clamp Fixtures.
During the 1950's and 1960's Adele's grandson D.V. Holman expanded the operation to include ADJUSTABLE "C" Clamps, JORGENSEN Hold-Down Clamps, PONY Spring Clamps, Band Clamps and Corner Clamps.
Great-grandson Daniel Holman increased the companies product line by adding JORGENSEN, PONY and ADJUSTABLE Bench Vises, JORGENSEN Miter Boxes and Miter Saws while expanding our original product offerings with new and inovative designs. Now under the leadership of our fifth generation of Holman's, Adjustable Clamp Company continues to manufacture tools only of the best quality and greatest value.
