ABSTRACT:
A ladder leveling leg has a universal clamping arrangement adapted for fastening to the rail of a ladder of various cross sectional configurations. The leg is adjustably mounted within a guide channel secured to brackets to which a clamping member is adjustably fastened to lock the guide channel to the rail of the ladder. The leveling leg is slidably mounted within the channel and may be secured thereto in selected positions by means of a detent resiliently urged toward cooperating holes in the leveling leg and the channel. Gripping members on the clamping member and one bracket frictionally engage the front and rear walls of the rail as the clamping member is secured to the brackets.
