These heavy gauge caps are made of galvanized steel for durability. A lower cost alternative to stainless steel, these caps feature corner mounting bolts for a secure installation. These caps are painted satin black. They are brand new and undamaged, but have been sitting in inventory, so the boxes may be a bit banged up. These are the heavier, old style caps. We have a limited supply of these in stock, so when they're gone, they're gone.
