Ladder guards

A top ladder guard is telescoped over the upper end of each siderail of a ladder to provide a protective mounting against a vertical supporting wall structure. Each ladder guard is a single piece cup-shaped member which is molded of a suitable soft rubber-like plastic and includes a body portion of a rectangular cross-section to fit over the upper end of a siderail and an integral outer curved end wall having a substantially curved configuration. The body portion includes a pair of main sidewalls formed as essentially smooth continuous members of an essentially constant thickness and a pair of narrow walls joining said main sidewall. The narrow walls are molded with a serpentine cross-section to form an accordian or expandable structure permitting expanding and contracting of the narrow walls. The narrow walls provide limited flexibility of the body portion for tight telescoping engagement with different sized siderails.
