The 7306 fiberglass 6 ft step ladder has a duty rating of 375 lb and features a heavy-duty aluminum HolsterTop?. With a full set of horizontals and heavy-duty internal spreaders, these ladders are built for the long haul. The molded external rail shields and the EDGE? bracing system help decrease damage to the rails. The slip-resistant TRACTION-TRED? steps are single riveted and have extra wide knee braces. The GLAS*MARK? violator stripes increase the visibility of the ladder on the jobsite. Fiberglass rails are non-conductive for working near electricity.
