About this detail

A double hollow structural section assembly frames at a spreader beam. The connection utilizes L6x4x1/4 by zero foot six inch angles with two two-and-one-quarter-inch long vertical laminated strand lumber blocks typically each side. A half-inch by six-inch by two-foot-six-inch plate is centered on the hollow structural section at the elevation specified by the manufacturer. Two hollow structural section L4x4x1/4 by zero foot six inch angles are included typically each side, secured with five-sixteenth-inch fillet welds. Two three-quarter-inch diameter ASTM A307 bolts spaced at three inches on center are centered in the vertical laminated strand lumber. A block-out on one side of the hollow structural section is provided for bolt access with a four-inch maximum clearance and a three-quarter-inch clearance gap.
