span clamps?!!? LMAO....round here no one, and i mean no one uses them...we just tie off with the messenger wire......
had a beauty the other day in downtown smyrna (smer-nah)....house has on the courner of a four way intersection, came from side of the subs house, across the street to a midspan...then down that midspan across the street (caddy corner from the house), tied off at that pole, then took a 90 turn going down the street away from the house to the tap.....great engineering on this design!!!
best tip to increase your time, is dont carry the windex with you like some other techs do.....
