A rope ladder in which the steps have a metal frame comprising a pair of longitudinal members joined by a pair of shorter transverse members spaced in from the ends and strengthened by a pair of diagonal members. At each end a metal bracket bridges across the frame and provides an elevated upper plate portion which defines a generally rectangular opening. A molded hard elastomer body is molded around the frame and has a collar portion at each end molded around the bracket. The body has a downwardly and outwardly flaring through opening in line with the bracket opening and vertical bolt openings therethrough adjacent each through opening. A separate wedge collar for each step has a tapered through opening going down to a narrow lower end. A generally diamond-shaped wedge heart in between each pair of ropes provides two rope-engaging side grooves for locking the pair of ropes in place and preventing relative movement between the ropes and the step, when fastening means extending through the bolt openings are tightened in place.
