Nonconductive wrench with wingnut tightener slots

A nonconductive stubby wrench with 1/2 and 9/16 inch sockets. The bottom has slots to use in tightening wing nuts. I use this when working with deep-discharge marine batteries and deep discharge golf cart batteries.

Update 1/26/18: I added an SGV variant of this for a lasercutter. Cut it in 1/4" Delron for a vast improvement in strength over the original version. Put colored silicone caulk in the lettering to make them legible.
