Fiberglass 8'' Step Ladder features a duty rating of 375 lb. and features an extra heavy-duty, aluminum HolsterTop with thick side plates. With a full set of horizontals spaced one per foot 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 nonconductive for working near electricity. Design also includes shoulder bolt and lock nut on top hinge.
