The Equalizer extension ladder from Werner Ladder is designed with factory-installed integrated leg levelers for added safety while working on uneven ground. The Werner-exclusive built-in EverLevel System is an easy-to-use integrated leveler. The leveler leg, with its dual-channel holes allows the ladder to be adjusted in 3/8-inch increments up to 8 ¼-inch to help the user set the ladder more accurately. A durable zinc-plated-steel locking pin with detent ball secures the leveler at the proper height. The Equalizer is available in two aluminum models — the D1700 Series, a Type II duty-rated model with a load capacity of 225 pounds and the D1800 Series, a Type I duty-rated model with a 250-pound load capacity.
