No Can a tie tube be joined for a scaffold? 37. Can an extended transom be used as a tie for a scaffold? No 38. Unless alternative engineering approval has been obtained, how many standards (or ledgers) must a tie be connected to for a tube and coupler independent scaffold? 4 39. What is the best way to support a two plank wide cantilevered platform and still use putlog clips to attach putlogs to ledgers? By using spurs 40.
