Just about everyone uses them but how many Co.'s out there permit the clamp to be installed directly on the bare wire?Seems like most places want a stirrup to attach it to.The newer type(last 30 or 40 yrs. or so) has a split washer to retain commpression that makes it a very dependable connection unlike the older style without the washer.Most of us out here would like to go right to the line(copper only for now) but we need the names of some Co's to help back up our agruement.Any ideas,good or bad?Thanks.
