About this detail

This elevation and plan detail shows a stainless steel stair security gate installed at an egress exit above a level change. The assembly features two-and-one-quarter-inch-diameter stainless steel pipe posts anchored to the finished concrete floor with a welded base plate secured by four expansion bolts. A one-and-one-half-inch by two-inch stainless steel tube forms the gate frame, equipped with a beveled collar and locking pin allowing two-way ninety-degree rotation with automatic return to the closed position. A twelve-inch vinyl sign with applied graphics, white background, red graphics, enter arrow, and no enter symbol is attached to one-inch aluminum angles mounted to the bottom of the tube frame. The gate stands three feet four inches tall with a clear opening width of three feet one inch, positioned adjacent to the stair stringer and wall.
