Has anyone had any experience with those add on plastic ladder treads for the standard fold down transom ladder?? Catalina Direct sells them but it appears that you either screw them or pop rivet them on through the 1" ladder rung. I fear this will only let in water and promote rust in the ladder. Has any one ever seen any ladder treads that clamps on the rung with out drilling holes?
