Werner Extension Ladder: 20 ft Industry Ladder Size, 17 ft Extended Ladder Ht, D-Rung, 58 lb Net Wt

This extension ladder is ideal for utility or telecommunication industries. Factory-installed levelers enable it to adapt to uneven terrain. With a simple foot action, each leveler can extend up to 10" in 3/16" increments. Rugged, heavy-duty extruded rung locks are spring loaded to operate smoothly. The D-rungs are slip resistant and the molded end caps are mar resistant. The external guides at the top of the base section secure the interlocking rails. The top of the fly section has prepierced holes for easy installation of accessories. The base and the fly sections are easily separated so the base can be used as a single ladder. The fiberglass rails are nonconductive for working near electricity.
