Carpenter Eric Roberts, of Archadeck of Suburban Boston, plumbs and levels the bench supports for a deck on grade.
Roberts secures the post to the deck frame with FastenMaster ThruLOK structural fasteners.
Roberts attaches the engineered washer and LOK-nut for the ThruLOK post connector.
After cladding the seat posts with Fiberon trim, Roberts lays a preservative-treated 2x4 in place against the post and scribes it out as he begins to frame the bench seat.
Roberts transfers his layout marking to the opposite matching piece for his bench seat frame.
