† Weight of spool and wire rounded to the next highest kg (lb) (does not include packing material). †† Overall color clear.
††† To order special limits of error wire, add “-SLE” to model number before spool length. * Has color tracers on jacket and conductors.
HH Wire has trace thread in positive leg, negative leg is red, overall has trace thread.
