Is it just me or what??? Here lately every knock out that is supposed to knock out stays and the wrong size pops lose or the darn thing won`t comeout with out killing the box.And also the darn switch ears don`t break off as designed Boy feel better now I vented.Yea operator error I`ve been told already.Last night 4' troff lights the knock outs would not push out with out laying the piece on the ladder and beating the hell out of it then you have to straighten the part back.
