3 Tools in 1

The Tri-Penta WrenchTM is an underground utility wrench that combines three everyday functions into one convenient tool.  The ¾” Penta Socket opens transformers and switch gears.  The addition of a high visibility patent-pending Speed SleeveTM helps linemen open those transformers and switch gears up to 2X faster than standard Penta sockets or wrenches.  It also comes with 2 other tools built into the handle – the integrated Lid Lifter lifts hand hole lids and the 3/8” Screwdriver is great for opening secondary or primary doors.
