About the 1/2" 3/4" & 1" x 20" Flat Stud Bracket
Sioux Chief 521-810 Flat Stub Bracket has a galvanized construction so it will not rust. It also is copper plated which allows it to do two things; 1. The copper keeps the bracket from getting hot, and 2. It has a larger design allowing for more soldering surface which in return provides extra strength.
