set of copper conductor heads. Buy one or more at 200 each. The front has an overflow hole to alert if lower drainpipe is blocked. Very nicely fabricated, well flanged with 50/50 solder joints. There are three removable top collars. Bottom fits into 3 " round, or 2 x 3 " rectangular downspout. One head was made with a blackish patina. The bright head with bottom downspout strap collar was waxed to stay bright longer. All will get dark and eventually get some green color. Full cleat flange at the back top for mounting/hanging on a cleat if wanted. Mostly made from 24 oz copper, with some 20 and a bit of 16 oz. The long curved joint flanges are stretched, not tabbed, for better strength, water tightness, longevity, and looks. With the ogee top collar, it's 18 high, 14 wide, and 8 " out.
