Little Giant King Kombo Industrial is the world\'s first and only 3-in-1 extension ladder, leaning ladder and stepladder combination, in one lightweight package. King Kombo was built for those who get stuff done! King Kombo has ultra-heavy-duty feet with seriously aggressive tread, for elite traction and durability in harsh industrial environments. King Kombo also brings a tough corner, pole, and stud gripping V-bar for the extension ladder position. This heavy-duty grip conforms to inside and outside corners and even offers protection for damageable leaning surfaces like paint, drywall, stucco and round poles. Fitted with the patent-pending Ground Cue‚ an audible and tactile signal to let you know you when you have reached the bottom step of the ladder.
