BOOT LACE PINS
CABAC bootlace pins are used to terminate conductors, by containing the strands in a thin walled copper sleeve that is crimped onto the conductor.
The sleeve ensures that no conductor strands stray, and also stops screws in the terminal from breaking strands.
The sleeves should be slipped over the stripped conductor, and crimped. Crimp is only to hold sleeve on conductor until screw of terminal housing makes connection.
