One tool for stripping, cutting, and crimping -- the WirthCo 80920 self-adjusting wire stripper automatically senses wire gauge from 10 to 26 AWG and strips cleanly without nicking or breaking strands. Built for RV wiring, trailer harnesses, and automotive electrical work.
The WirthCo 80920 is a purpose-built electrical hand tool that eliminates the guesswork of manual wire strippers. The self-adjusting jaw mechanism automatically calibrates to the wire diameter before stripping, so you get a clean strip on multi-strand wire every time -- no adjusting a dial, no accidentally cutting through the conductors.
The built-in crimping section handles both insulated and uninsulated terminals, making this a practical all-in-one for wiring up trailer connectors, 12V accessories, solar components, and any other electrical project around your rig or tow vehicle.
Automatically senses and adjusts to wire gauge from 10 to 26 AWG -- no dial setting required before each strip.
Strips multi-lead trailer wire in one smooth motion without nicking or breaking individual wire strands.
Crimps both insulated (color-coded) and uninsulated butt connectors and terminals for a wider range of electrical work.
Steel construction provides long-term durability. Yellow rubber-coated handles reduce hand fatigue during repeated use.
RV and trailer electrical systems use a wide variety of wire gauges -- from 10 AWG on brake controllers and heavy accessories down to 26 AWG on sensor leads and signal wires. A self-adjusting stripper means you can move between gauges without stopping to recalibrate, which matters when you're tracing a wiring problem under the rig or installing a trailer plug in the driveway.
The WirthCo 80920 is particularly well-suited for multi-conductor trailer wiring (4-flat, 5-wire, 6-wire, and 7-wire harnesses). The self-adjusting mechanism strips the individual leads of flat or round trailer cable cleanly in one motion, which saves significant time compared to a manual stripper that requires repositioning for each gauge.
The crimping jaw on this tool is designed for standard insulated terminals (red/blue/yellow color-coded) and uninsulated butt connectors. It is not intended as a replacement for a dedicated ratcheting crimper on high-current or marine-grade crimp work. For heavy-duty ring terminals on battery cables, use an appropriate heavy-gauge crimper.
