CST/berger is the union of two measuring tool specialist
manufactu-reres: Chicago Steel Tape, founded in 1903, and Berger
Instruments, founded in 1871. While Chicago Steel tape specialized
originally in the manufacturing of precision long tapes for land
surveyors, Berger specialized in the development and manufacturing of
precision optical instruments. After acquiring Berger Instruments in
1994, the merged CST/berger developed global leadership in designing,
developing & manufacturing leveling and layout instruments and
accessories for the building, construction and survey markets.
In July 2008, CST/berger was acquired by the Robert Bosch Tool
Corporation, creating one of the the worlds leading manufacturer of
layout and measuring tools.
