Abstract
A standoff device and ladder designed for positioning with respect to a supporting structure, the standoff is temporarily and rigidly attached to the upper end of a ladder for the purpose of holding the ladder away from the structure against which the ladder is leaning to provide more stability and a comfortable distance between the user and the structure during tasks such as painting, power washing a house, working with gutters, carpentry, roofing, tree trimming and pruning. The standoff comprises a pivotal frame which is moveably and adjustably secured to a selected rung of the ladder with the pivotal movement limited by a chain, rope, strap, strut, telescoping member, or other holding element attached to a lower portion of the ladder such as a lower rung. The standoff device includes a frame having extendable legs with padded rollers journalled on the end in a “V-shape” for leaning against various shapes of vertical support structures such as walls of a building, columns or trees.
