Boris Rogelja founded Single Rope Technique Equipment (SRTE) in 1980. Capital Safety Group acquired SRTE in 2011 and their devices started showing DBI-SALA, Capital Safety, and/or Rollgliss™ markings. Some of these continued to show SRTE markings, and some did not. There does not appear to be a specific date when the markings disappeared. Different devices removed the SRTE logo at different times. 3M acquired the Capital Safety Group in 2015 and the Single Rope Technique Equipment markings disappeared completely.
