Klein Tools 21050 – Frequently Asked Questions

1) What wire sizes does the Klein Tools 21050 cable stripper handle?
The Klein 21050 strips four large conductor sizes: 350 MCM, 500 MCM, 600 MCM and 750 MCM. That is the clover design, four ports in one head, so a crew terminating a range of feeders in a panel isn't carrying four separate strippers. Anything below 350 MCM won't be held correctly by these ports, so for smaller building wire you need a different stripper.
2) Will the Klein 21050 stripper work on THHN and THWN-2 building wire?
Yes, it's built for MTW/THHN/THWN-2 insulation in the 350 to 750 MCM range. The description also names cable from CME Wire and Cable, Encore Wire Corporation, United Copper Industries and Southwire as brands it works with. Insulation type matters on a tool like this because the blade depth is set for that jacket thickness, not adjustable.
3) How does a twist-type large cable stripper compare to using a knife on 500 MCM?
Insert the conductor into the matching port and twist, and the blade scores a clean ring at a fixed depth. A knife on 500 MCM is freehand, and a nick in the strands is what you're trying to avoid on a terminationthat carries real current. The Klein 21050 gives a repeatable cut without adjustment, which is the argument for it on switchgear and service panel work where every lug looks the same and there are a lot of them.
4) Is the Klein 21050 cable stripper small enough to work inside a crowded panel?
The head measures 4.656 x 4.656 x 1.75 inches and the tool weighs 1.25 lbs, so it's a one-hand tool you can bring to the conductor rather than pulling the conductor to a bench. In a packed gutter or a switchgear section with feeders already dressed in, that size is the deciding factor.
5) Can the blades on the Klein 21050 be replaced when they dull?
They can. The 21050 uses powder metal blades in an aluminum body, and replacement blades and screws are available, so a dull tool is a blade change rather than a new tool. That matters for an MRO or shop crib buying one stripper to be shared across a crew for years.
6) What is the Klein Tools part number for the large cable stripper for 750 MCM?
Klein Tools model 21050. It is sold as a single model, no size or finish options to pick, and it covers 350 through 750 MCM in one head.
