Ratcheted for Full Compression Cycle. A ratcheted crimp tool requires the installer to complete the full crimping cycle. While some RJ45 brands are eliminating this feature with their crimp tools, Simply45® knows that a ratcheted crimp tool is critical to ensuring that the RJ45 pins are properly seated onto the wire conductors and the pass-through wires are properly trimmed. A ratcheted crimp tool prevents incomplete plug termination. Synchronized Handles = More Force with Less Hand Effort. TheSimply45® Pass-Through RJ45 Crimp Tool S45-C100 uses synchronized handles that compress together during the crimping cycle. This synchronization delivers consistent and even force directly to the plug socket and the wire trimming. The result is a smoother, faster, and easier crimping process. The Simply45® Pass-Through RJ45 Crimp Tool S45-C100 provides more leverage than any other RJ45 crimp tool. The tool handles open up to 4.25” (108mm). This leverage delivers more force with less hand effort during the crimping cycle. Other RJ45 crimp tools may work ok when you are crimping Cat5e, but when you start crimping Cat6 or Cat6a LAN cables, it usually takes both hands squeezing strongly to complete the crimp cycle. This is because most other RJ45 crimp tools use only ONE handles to generate the crimping force. The Simply45® RJ45 Crimp Tool design utilizes BOTH handles working in tandem to deliver the crimping force with much less effort. Crimping Cat6 cables with one hand is easy to do. This lowers the hand fatigue, especially when you have many terminations to complete in a day.
