About Us, The Collins-Phillips and Pi Tape Texas, LLC History
It is impossible to have a legitimate conversation about diameter measuring tapes without focusing on the names of Norman Collins, Leo Cochran and Harold Phillips, the individuals who invented and advanced the Pi Tape® measuring device system.
Norman Collins circa 1961
Harold Phillips circa 1967
In 1944, while working at Solar Turbines in San Diego, Norman Collins developed a measuring tape method that would accurately measure diameter utilizing circumference measurement. Also in the mid 40's, Leo Cochran saw Norman's innovation and advanced his own company. As Norman's business grew, he was introduced to Harold Phillips, Sr., a retiring calibration technician for the Atlas Missile Guidance Systems. In 1966, Harold and Norman partnered and changed the name from Norman Collins Company to Collins-Phillips Tool Corporation. Ultimately the Pi Tape® brand name and logo were introduced, making Pi Tape Texas, LLC's products
synonymous with accurate precision diameter measurement on a global level.
