ABSTRACT:
A tree stand extension device has a rectangular, hollow base frame. The base frame has a center beam connected centrally, along a long axis, to the base frame. A plurality of engagement arms are attached to the base frame and the center beam to hold a tree stand. The plurality of engagement arms are parallel to each other along a short axis of the base frame and are a predetermined distance apart. The device further includes a pair of top attachment arms and a pair of corresponding bottom attachment arms. The pair of top attachment arms are coupled to the pair of corresponding bottom attachment arms, wherein a tree stand positioned on the remaining end of the plurality of engagement arms is encased therein by the pair of front attachment arms and the pair of corresponding rear attachment arms. In one embodiment, the coupling is accomplished by having a plurality of apertures in each of the pair of front attachment arms and the corresponding rear attachment arms. Bolts and nuts are then used to couple the device. The base frame and center beam have a non-skid material applied to aid footing.
