Abstract
A ladder attachment may allow a ladder to securely rest on a corner of a structure, structure corners, tree, or the like. The attachment may be attached to the rung of a ladder via several mounting brackets and mounting flanges. The attachment includes first and second arms which may be arranged at about a 90° angle to allow the positioning a ladder on the corner of the structure or oddly shaped structures during use.

A ladder safety apparatus, comprising:
- a top plate comprising a body, a first arm, and a second arm, the first arm and second arm extending away from the body of the top plate approximately perpendicular to one another, the top plate defining a first through hole and a second through hole therein;
- a bottom plate defining a third through hole and a fourth through hole therein;
- a web connecting the body of the top plate to the bottom plate;
- a first mounting bracket comprising a first mounting flange and a second mounting flange each constructed and arranged to engage with a rung of a ladder, the first mounting bracket defining a fifth through hole and a sixth through hole;
- a second mounting bracket comprising a third mounting flange and a fourth mounting flange each constructed and arranged to engage with a rung of a ladder, the second mounting bracket defining a seventh through hole and an eighth through hole;
- a first plurality of nut and bolt combinations constructed and arranged to thread through the fifth, sixth, seventh, and eighth through holes to mechanically connect the first mounting bracket to the second mounting bracket such that a rung of a ladder is engaged by the first, second, third, and fourth mounting flanges;
- and
- wherein the top plate, web, and bottom plate are constructed and arranged to mechanically connect to the mechanically connected first mounting bracket and second mounting bracket such that the top plate, web, and bottom plate are secured to a rung of a ladder.
