Size: 1/2 prybar wrench adapter. 【Pry Bar Wrench Adaptor】I like the adjustability of this which will work in a variety situations，can be used with a 1/2 socket as well，but I thing the breaker bar would be better use of this pry bar head，prybar wrench adapter，This tool is great for getting into tight machines that need a little extra leverage.
