The Extron CTU 300 is the single tool necessary to terminate all Extron coaxial cables and other compatible cables using Extron's high-quality, reliable BNC crimp connectors. Extron's exclusive precision-machined, self-aligning FastBite die - patent pending - ensures accurate, consistent crimp connections. The crimp termination performed by the CTU 300 passes stringent pull-testing for durable, long-term, secure crimps that will survive the most rigorous environments. The unique four-in-one die has quick-view color-coded markings for ease-of-use, and the lightweight ratchet-controlled frame enables minimal, one-hand effort for complete crimp cycles.
