The painted steel ladder assembly features rails that are bent and aligned with support brackets. These 3/8-inch by 4-inch support bracket plates are welded to the ladder rails and secured to the concrete wall using 1/2-inch by 4-inch expansion bolts with galvanized bolts and washers. The ladder terminates above a 4-inch concrete slab, with metal siding molding provided to accommodate the supports. Wall type and thickness must be verified prior to fabrication to ensure proper anchorage.
