The original Posi-Clamp was developed by Mr. Ralph West in 1956 and had been fabricated by the Ralph West Company for over 50 years.

In 2007, the Ralph West Company was acquired by S&S Machine Shop, Inc. All staff and procedures were retained. The Posi-clamps are made by experienced machinists at a very competitive price, and can be shipped anywhere in the world.
