Key Features
Overview
The Klein Straight Locknut Wrench Set (50901R) is a three-wrench set for tightening and loosening conduit locknuts in tight and hard-to-reach spaces. It includes one wrench each for 1/2 in., 3/4 in. and 1 in. conduit.
The convenient U-shaped end gets onto locknuts where pliers will not fit, and an extra tooth on the hook gives improved turn leverage. The slim steel design is corrosion resistant and durable, and each wrench is a different color and marked with its size so you can grab the right one fast.
Two internal magnets on each wrench hold the set together for easy storage. The set measures 5.8 in. (147 mm) long, 1.7 in. (43 mm) wide and weighs 3.03 oz (86 g). Electricians who install conduit and fittings will get the most out of it.
