Abstract
Abstract A bundle of stiff, resilient strands form a flag to be attached to the top of a grade stake for use in construction work such as road building. The cluster of strands are folded into a bight and held in two loops of a metal strip which also has a large loop which may either encircle a large nail or be driven into a wooden stake without splitting the stake.
