Water meter socket adapter

This is a redrawn socket adapter for opening a water meter box, using the concept from pillthomas. This adapter will fit 13/16" (.8125" point to base) pentagonal bolts commonly used on water meter boxes and it fits a 1-1/8" socket.

There are three files - the base one is designed to be slightly larger for the bolt opening as I found mine had swollen with corrosion a bit and the "proper" size was a little too tight. The "exact dimension" file is the tight fit, so adjust if needed to fit for your uses.

edit 2/27/17 - I've added the "largest adapter" file, which opens up the bolt opening a hair bit more and makes for the best fit on my meter.
