Abstract: A post holder is provided with a breaking arrangement to hold a post without application or external force even under the influence of gravity. In the preferred embodiment, a post holder is provided with a shoe which contacts the post. The shoe is urged toward the post with a spring, in the preferred embodiment a single convolution spring. Preferably, the shoe has a relatively large face area contacting the post, thereby provide more positive locking of the post relative to the post holder with the application of lesser external force. Ideally, the spring applies sufficient force on the shoe that the post does not move under the force of gravity. In operation, the user may remove the external force, move the post relative to the post holder, and reapply an external locking force, at any time the post being supported by the breaking arrangement. In this way, the user may move the post relative to the post holder with a single hand.
