Best RJ45 Plugs and a Crimper for Clean, Reliable Ethernet Terminations
Terminating Ethernet cable is a job that rewards the right tool, and a pass-through crimper paired with matching RJ45 plugs removes most of the guesswork. This guide covers five kits that suit first-time installers running cable through a house, home-lab builders wiring a rack, and anyone repairing a damaged patch lead. Each pick includes a crimper and connectors, and most add a tester or boots. The overview below shows the differences at a glance before the full reviews.

1. RJ45 Crimp Tool Kit Pass Thru Ethernet Crimper
Type: Pass-through crimping tool kit
Compatibility: Cat5e, Cat6, Cat6a, 8P8C modular connectors
Included: Crimper and cable tester
Power source: 9V battery for the tester (not included)
Best use: First-time installers who want testing built in
This kit pairs a pass-through crimper with a network cable tester, which covers the two steps that trip up most beginners: seating the wires in the right order and confirming the finished cable actually works. The pass-through design lets the wire tips push out the front of the plug so they can be checked visually before the crimp closes. The tool handles the common 8P8C connector family across Cat5e, Cat6 and Cat6a cable, so one purchase covers most home and small-office runs.
It suits someone wiring a house or repairing patch cables who wants a single box rather than separate tools. The tester needs a 9V battery, and the kit does not ship with one, so a first-time user should have one on hand before starting work.
Trade-off: The tester is a convenience addition rather than a lab-grade instrument, so the crimper is the star of this kit.
2. Klein Tools VDV226-110 Ratcheting Modular Data Cable Crimper
Type: Ratcheting modular crimper, stripper and cutter
Compatibility: RJ11, RJ12 standard and RJ45 pass-through connectors
Function: Crimp, strip and cut in one tool
Build: Ratcheting mechanism
Best use: Trade work and repeated terminations
This is the pick for anyone who terminates cable often. The ratcheting mechanism holds the plug firmly and completes the crimp in a controlled motion rather than relying on hand strength, and the tool combines crimping, stripping and cutting so a single hand tool covers the whole job. It works with RJ11 and RJ12 standard connectors as well as RJ45 pass-through plugs, which makes it useful for phone and data work alike.
It suits electricians, IT installers and serious home-lab builders who want a tool that will survive years of use and are willing to pay for that durability. Buyers who only need to fix one cable a year will find it more tool than the job requires.
Trade-off: It is a bare professional tool with no tester and no connectors, so the plugs and any testing gear must be bought separately.
3. Solsop Cat7 Cat6 Cat5 Crimping Tool Kit with 50 Connectors
Type: All-in-one pass-through crimp tool kit
Compatibility: Cat7, Cat6, Cat5 cable
Included: Crimper, network cable tester, 50 Cat6 pass-through connectors, 50 connector boots
Best use: A complete Cat6 termination job in one box
This kit is the most complete package of the group for a single project. It ships with the crimper, a tester, fifty Cat6 pass-through connectors and fifty boots, so a buyer can wire a full patch panel or a run of room drops without ordering anything else. The pass-through connectors are the style the tool is built for, which keeps the seating and crimping steps consistent across every cable.
It suits someone wiring a new home network or finishing a home lab who wants the connectors and strain-relief boots included in the same purchase. The Cat7 listing in the compatibility is worth noting, though the included connectors are Cat6.
Trade-off: The included connectors are Cat6, so a buyer running Cat7 cable for the higher rating will need to source matching plugs separately.
4. Solsop CAT5 Cat5e Cat6 Crimping Tool Kit
Type: Pass-through RJ45 crimp tool kit
Compatibility: Cat5, Cat5e, Cat6 cable
Function: Pass-through crimping
Best use: Straightforward Cat5e and Cat6 patch cables
This is the stripped-back version of the Solsop kit: a pass-through crimper aimed at the most common home and office cable, Cat5e and Cat6. The pass-through design means the wire ends can be inspected before the crimp is made, which is a real advantage for anyone who has ever found a crossed pair after the plug was already closed. It is a sensible, no-frills tool for the person who already has connectors and a tester on the shelf.
It suits occasional users making up patch leads or replacing a broken plug on an existing cable. Buyers starting from nothing should look to a kit that includes connectors and a tester instead.
Trade-off: The kit is the tool alone, so the connectors and tester that a first-time job needs are not part of the package.
5. Gaobige Ethernet Crimper with 50 Connectors and Tester
Type: Pass-through crimping tool kit
Compatibility: RJ45, RJ12, RJ11 connectors; Cat6, Cat5e, Cat5 cable
Included: Crimper, 50 Cat5e pass-through connectors, 50 covers, network cable tester
Best use: Small jobs that need spare connectors and a tester
This kit bundles the crimper with fifty Cat5e pass-through connectors, fifty covers and a network cable tester, which makes it a practical choice for a modest wiring job. The tool handles RJ45 as well as the smaller RJ12 and RJ11 connectors, so it covers data and phone terminations with one unit. The pass-through design keeps the wire ends visible until the crimp is closed.
It suits a homeowner running a few drops or replacing damaged cables who wants connectors and a tester without buying a larger kit. The connectors are Cat5e, so a buyer working with Cat6 cable will want to confirm plug compatibility before starting.
Trade-off: The included connectors are Cat5e rather than Cat6, which limits the kit for anyone wiring newer cable.
Before You Buy
- Connector type: Pass-through crimpers need pass-through plugs; standard plugs will not work in them, so match the plugs to the tool.
- Cable category: Buy connectors rated for the cable being terminated — Cat5e plugs on Cat6 cable waste the cable’s headroom.
- Compatibility: Check that the crimper covers the connector family in use, including RJ11 or RJ12 if phone terminations are planned.
- Included accessories: A tester and boots save a second order; a bare tool keeps the cost down for buyers who already own them.
- Battery: Testers that run on a 9V battery usually ship without one, so add it to the list.
- Build quality: A ratcheting mechanism helps with repeated crimps; a basic tool is fine for occasional work.
Frequently Asked Questions
-
What is a pass-through RJ45 crimper?
A pass-through crimper is designed for plugs where the wire ends push through the front of the connector, so the installer can check the wire order before crimping. -
Can one crimper handle both RJ45 and RJ11 connectors?
Some models, including the Gaobige kit, list RJ45, RJ12 and RJ11 compatibility; others are built for RJ45 pass-through plugs only. -
Does a crimper kit include the connectors?
It depends on the kit — the Solsop all-in-one and Gaobige sets include fifty connectors, while the Klein Tools crimper is the tool alone. -
Is a cable tester necessary?
A tester confirms the finished cable works and shows which wire is faulty if it does not, which saves time on a multi-cable job. -
Do the tester batteries come included?
The RJ45 Crimp Tool Kit lists its 9V battery as not included, so it is worth checking each kit before starting work. -
Which cable categories do these kits cover?
The picks cover Cat5, Cat5e, Cat6 and, in the Solsop all-in-one, Cat7 cable, though the included connectors may be rated lower than the cable.
Bottom Line
For most buyers the RJ45 Crimp Tool Kit Pass Thru Ethernet Crimper is the easiest starting point, pairing a pass-through crimper with a tester in one purchase. Anyone terminating cable regularly should step up to the Klein Tools VDV226-110 for its ratcheting build and combined strip, cut and crimp function.
