About this detail

An assembly detailing a one-and-a-half-inch outside diameter stainless steel pipe handrail mounted thirty-six inches above the stair nosing onto masonry, concrete, or cold-formed metal stud frame walls. The handrail welds to a three-eighths-inch stainless steel structural bracket and a four-inch stainless steel wall plate with ground-smooth connections. On masonry or concrete walls, the wall plate secures with three one-quarter-inch diameter stainless steel Tapcon concrete screws. On gypsum board and metal stud walls, the wall plate secures with three one-quarter-inch diameter stainless steel toggle bolts anchored through plywood blocking and six-inch eighteen-gauge metal stud blocking. Additional details show pipe sleeves with recessed Allen set screws at the bottom fitting inside the handrail diameter, with intermediate wall supports spaced equally at a maximum of four feet on center.
