  • Tests voice, data and video cables with clear results
  • Measures cable length up to 2000 feet (610 m)
  • Detects Open, Short, Miswire and Split-Pair faults
  • Punchdown tool terminates and cuts CAT3, CAT5e, CAT6/6A in one step
  • Ratcheting crimper strips, cuts and crimps STP/UTP paired-conductor cables

Complete cable-testing kit

This kit combines a cable tester, an impact punchdown tool with a 66/110 blade, and a ratcheting modular crimper that also strips and cuts wire. It is built for installers and technicians who need to verify, terminate and connect voice, data and coax runs in one package. The tester checks RJ11, RJ12, RJ45 and F-connector cables, while the punchdown tool seats wires into 66 and 110 blocks and the crimper handles pass-through RJ45 plugs.

Backlit LCD readout and tone tracing

The tester shows cable length up to 2000 feet, wiremap, cable ID and fault results on a backlit LCD for clear reading in dim spaces. It detects open, short, miswire and split-pair faults and includes a hub-blink mode to locate ports on a switch. An analog probe (VDV500-123) can be added for tone tracing, and five LanMap plus five CoaxMap remotes let you map multiple runs in a single step.

Replaces separate tester, punchdown and crimper

Buyers who currently carry three individual tools can consolidate to this kit and reduce pouch weight. The jump is worth it when you regularly terminate CAT3, CAT5e and CAT6/6A into 66/110 panels and also need to verify coax and twisted-pair links on site. It does not suit buyers who only need a basic continuity checker or who require a punchdown blade for a different block type.

Questions about this item

How do I install the 66/110 blade on the punchdown tool, and what step do people get wrong?

Align the MIM precision-ground combination 66/110 blade with the tool head and press firmly until it locks; the common mistake is not seating it fully, so the blade slips during termination and leaves wires uncut.

What maintenance will the crimper/stripper/cutter need later?

Keep the ratcheting mechanism clean of copper shavings and apply a drop of light machine oil to the pivot points every few months; the hardened steel jaws do not need sharpening under normal use.

What limit shows up first when I test many long cables in a row?

The backlit LCD draws the most power, so the 9 V battery typically runs down after several hundred length measurements up to 2000 feet, ending the session until you swap in a fresh cell.
