Mac Allister Aluminum Extension Ladder - A Mac Allister aluminum extension ladder featuring square-section rungs with corrugated interior surfaces for increased grip. The rungs are swaged into the hollow rectangular side rails. The side rail is printed with the maker's name in a stylized black font reading MAC ALLISTER. The ends of the rails are fitted with textured blue plastic caps. A loose rectangular section of aluminum box tubing is shown resting against the ladder structure. The ladder appears to be a multi-section extension variety, though the total number of sections and rungs are not visible in this detail view.
