A cross-laminated timber stair stringer is supported by a cross-laminated timber bearing wall and an L7 ledger. The connection incorporates recessed bolts through the timber elements with Douglas fir wood plugs to conceal the hardware and match the exposed timber appearance. Section views detail the bolt spacing pattern of two inches, five inches, five inches, and two inches along the connection interface.
