Simply45 is the industry-leading brand for RJ45 modular plug innovation and performance solutions. S45-C100 Pass Through RJ45 Crimp Tool for unshielded and internal ground shielded Pass Through RJ45 modular plugs is a breakthrough in professional pass through RJ45 termination.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, Simply 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. The Simply45 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 are crimping Cat5e, but when 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 handle 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 have many terminations to complete in a day.Steel Reinforced for Greater Stability. wrapped the Simply45 Pass Through RJ45 Crimp Tool S45-C100 with reinforced steel to ensure tool stability during the crimping cycle. When analyzed other RJ45 crimp tools on the market found that tools using various inserts introduced a lot of instability during the crimping cycle. Overtime this instability causes poorer wire trims and incomplete RJ45 pin setting onto the wire conductors. Crimp tool stability results in a smoother crimping cycle, better pin sets, more consistent wire trimming and greater durability over time. You can compare this to chefs in the kitchen. They can tell immediately if they have a good carving knife. They can truly feel the difference in the , the feel, the balance, the compared to a cheaply made knife from China. That carving knife works smooth with less effort. In industry the professional installer is the chef and RJ45 terminations are done in his kitchen. That is why professional installers should only use the best professional tools for the best professional results.
