Abstract:
A ladder leveling attachment (10) for adjusting the length of one or both legs of a ladder (L) to compensate for uneven surfaces, has a housing (11) with means (12, 13, 14) for securing it to a leg of a ladder, and an extendible leg (15) is telescopically received in the housing for movement inwardly and outwardly of the housing to selectively increase or decrease the length of the leg. A plurality of angled notches or slots (25) are formed in the housing and a spring-biased latching pin (35) is carried by the extendible leg and is adapted to engage in the slots for latching the extendible leg in an adjusted position. The opposite ends (38, 39) of the latching pin project outwardly beyond the opposite sides of the housing and may be grasped in one hand to release the latching pin from the slots to move the extendible leg along channels (24) to a new position. Thereafter, the pin is simply released and the spring urges the pin into seated engagement in adjacent notches (25).
