Wrench for turning the valve handles on 1 1/2"-2" backflows and small valve handle wrench for the backflows up to 1". They are made out of aluminum and work with a 3/8" Rachet Wrench. They are not gold in color for some reason the aluminum silver color wants to turn gold in the pictures. The handle is made so the curved handles on the larger backflows fits just right. There is also a larger opening for the nut to fit into. Wrenches makes it a lot easier to turn those stubborn valves. There are some Apollo backflows that have a large handle that the small wrench won't fit. It is a discounted price to buy both at once.
