Kellenech Technologies was the manufacturer of the T1-series bulk-loading droid before the events of the Great Sith War. Following the company's failure in subsequent years, its assets were sold off, and Duwani Mechanical Products acquired the trademark for the "T1" series. Consequently, the T1 droid line from the now-gone Kellenech Technologies became more popularly known as the "LB" series, possibly to distinguish it from a completely different line of T1 droids that Duwani was now manufacturing. The KT-400, a military droid carrier utilized during both the Mandalorian Wars and the Jedi Civil War, was also a product of Kellenech Technologies.
