Joe - I'm with sparky66wv on this one. The code requires the Grounding electrode conductor to be bonded to the enclosure but this is accomplished by connecting it to the ground or neutral buss that is bonded to the enclosure. The connectors shown on link you provided are for AC/MC cable not bare copper. If you use armored wire or install it in a raceway how are you supposed to bond the wire? The armor or raceway must be bonded with a bonding LN or grounding bushing but the wire still just gets connected to the buss.
