Assembly features four bolts arranged in two pairs, with a two-inch edge distance from the outer bolts to the edge of the connection plate. Spacing between the two bolts in each pair is two and one-half inches. Centerline of the ladder is aligned with the centerline of the stringer, with the bolt pairs spaced symmetrically from this axis.
