Review: One of those simple tools that makes electrical work much easier - I work in generator service and do electrical work in transfer switches, control panels and other tight enclosures on a regular basis. These are one of those tools I didn’t realize how much I’d appreciate until I started carrying them. Trying to tighten or remove conduit locknuts with pliers or a screwdriver works, but it’s awkward and usually ends up chewing up the locknut. These fit properly and the offset design makes a huge difference when the locknut is buried against the side of an enclosure where there’s barely enough room to get a tool on it. The 1/2”, 3/4” and 1” sizes cover most of what I commonly run into in the field, and I really like the magnets that keep the set together in my tool bag. Typical Klein tool—simple, well thought out and made for a specific job. If you regularly work inside electrical panels, transfer switches or junction boxes, these are absolutely worth throwing in your tool bag.
Review: Super - I love it thanks
