Review on Gardner Bender LNW-KIT Locknut Wrench Kit - Efficiently Loosen & Tighten ½ & ¾ Inch Locknuts with UL Compatibility - Heavy-Duty Steel Construction - 2 Pack Bundle, Black by Christopher Lance

Conduit Nuts can present a challenge when going directly into a wire-filled panel or junction box. Sometimes you just can't get to it with pliers to tighten or loosen, so come with a flat head and a hammer. Not exactly perfect. These little wrenches have saved me so much time and effort on electrical jobs that they have paid for themselves many times over. They're thin enough to get into those tight spaces, but strong enough to get the job done. I doubt they will ever wear out or break, but if I ever lose one I'll order another immediately. They will always be in my power tool kits from now on.
