Abstract
A cathodic protection system for a burial casket comprises a sacrificial anode rod, nylon sleeves encircling the rod and metal straps positively positioned relative the sleeves and welded to the casket bottom. One of the sleeves encircles the resistor of the system. The lead of the resistor connected between the casket and strap is carried in a slot in the one sleeve. The strap includes a welding dimple and a dog-eared corner which traps the lead between the casket bottom and the strap during welding of the strap to the bottom.
