   I am not sure what it fits, but it is a combination box-end and spanner wrench. The box-end part is easy, the spanner end fits in a pair of slots in a cap or retainer, typically one that has a hub or axle protruding from the center. Typically this type wrench would have been supplied with a particular machine to make adjustment or repair simplier. Not many of us have an assortment of spanner wrenches laying around.

   I just bought an adjustable spanner wrench from Garret Wade. I found I was short the proper sized spanner when I needed a custom collar to attach a disc to my Bosch angle grinder.Frosty“If you put the federal government in charge of the Sahara Desert,

   Any old furnaces or boilers in that basement? Wouldn't be surprised if it loosened a fitting thereon.

   It looks like the type of wrench made for water filters, oil filters, and water softeners. Is there a manufacturer's name on it?

   A google search reveals that Champion Brass makes sprinkler systems. It is probably the tool used to remove and install sprinkler heads.John White

   That's it, John. I have one just like it - although I haven't used Champion sprinkler heads for several years.

   This tool is commonly held by the short end with the wider u placed around the neck of young children. Works well for keeping toddlers at a distance while spending hours surfing message boards.

   I think it's a modern day boot jack.

   Tool for brass sprinkler heads. Hex end tightens/loosens spray nozzles; spanner end fits into two notches to tighten/loosen the whole head from the riser.

   Makes sense. It was hanging on the end of the workbench closest to the water shutoff valves. Thanks!Janet
