An MC6x15.1 channel stair stringer with a one-half-inch cap plate connects to a one-half-inch end plate via a three-sixteenth-inch fillet weld, with side, top, and bottom welds ground smooth. Two three-quarter-inch-diameter by three-and-a-half-inch-embedment Hilti HIT-HY 200 V3 adhesive anchors secure the end plate to a concrete wall sized per plan. The connection interfaces with a four-inch slab on grade reinforced with number four dowels at twelve inches on center. Treads and risers are coordinated per architectural drawings.
