What happens here
The builder demonstrates the proper method for attaching a ledger board to an existing wall. He first shows a common mistake of using nails, explaining they provide insufficient pull-out strength. Then, he correctly attaches the ledger directly to the wall studs using structural screws, highlighting that this method offers superior resistance to pull-out and shear forces.
Goal: Securely attach the ledger board to the existing structure with maximum strength.
