Pass-through plugs made RJ45 termination beginner-proof; the Jonard UC-4569 makes it production-fast.
This 6-in-1 crimper handles RJ11, RJ12, and RJ45 pass-through connectors across CAT3, CAT5/5e, CAT6, and CAT6A cable, crimping 4-, 6-, and 8-position modular plugs with a vertical crimp action that seats pins perfectly every cycle — no measuring the untwist, just push the wires through, verify the order, and squeeze.

The flush trim is the pass-through payoff, and this tool's is clean.
Wires trim flush to the end face of pass-through RJ11/12 and CAT6A RJ45 connectors — no proud copper stubs to short in a jack — and the heavy-duty cutting blades are rated for up to 400 cuts with a replacement set (UC-4569RB) available to keep the tool in service indefinitely. A detail most crimpers at this price skip: unique crimping slots in the middle of the tool crimp the tails of shielded RJ45 CAT6A connectors, so shielded terminations don't require a second tool.

The ratcheted, ultra-stable platform completes every crimp with low hand force — no half-crimped plugs, no death grip.
It also cuts and strips round STP/UTP and flat phone cable (22-28 AWG, solid or stranded), covering prep and termination in one steel-built tool with dual-material cushion grips. Pair it with the pass-through plugs we stock and a spool of Cat6, and a whole building's drops go faster.
