This HighRise adapter bracket allows the RETRAC HighRise folding rear entry step to fit on semi trucks with a 3” x 2” bumper. The bracket is specifically intended to fit the HighRise step #409924 (sold separately). It installs together with the step hardware, allowing the step to be mounted onto the smaller bumper beam size. The bracket is constructed from the same high-strength steel as the step itself, and it offers an easy installation.
