A hanging device attachable to overlapping siding members for supporting objects comprises an insert edge extending outwardly from an upper section, an offset section, and a lower section. The insert edge is insertable into the joint between adjacent siding members and the lower section includes a support element adapted to retain objects. The offset section extends between and joins the upper section with the lower section, with the offset section spacing the lower section from a siding member when the insert edge is inserted between adjacent siding members. The hanging device may be biased about a pivot area when an object is held by the support element such that the insert edge is urged into the joint between adjacent siding members. The insert edge defines an obtuse angle relative to the upper section and the support element may comprise hook members or mounting holes.
