6 Oatey Copper Roof Flashing Plates
$ 60.00
Six Oatey protrusion caps that use copper for the flashing. None look to have holes in them from screws or nails, but the rubber sleeve looks like it has been wrapped around something for a while. Maximum width pipe (outside diameter) is ~2 1/4". Plates are 8 3/4" x 12 1/2". Found these online for $50+ each. For this price, you could afford to use them as project copper.
