ABSTRACT:
A ladder support for imparting lateral stability to a ladder includes a C-shaped channel member for each side leg of the ladder. A first shoe member is slidably received and lockable longitudinally within each channel and is pivotally connected to a brace member which in turn is pivotally connected to a second shoe member which is also slidably receivable within the channel member. The second shoe members may be positioned outwardly of the ladder on an appropriate support surface and the first shoe members locked in place. The ladder is held by the support assemblies against any lateral forces which might tend to otherwise tip the ladder. When not in use the shoe members are compactly stored within their corresponding channel members.
