Abstract: A mobile barricade support device employs one or more rolling weight-supporting platforms, with a vertical strut extending from each of the one or more platforms to engage and support a barricade wall. The platforms may optionally be fixedly secured together by a horizontal strut and one or more backing brace members may optionally be secured to the platforms and the vertical struts for additional support.

Abstract: Embodiments of a parapet clamp device employ struts, a strut clamp, an L-connector and a clamp arm assembly. The device can securely nest a strut within the strut clamp and the strut clamp within the clamp arm assembly so as to promote sliding engagement to a desired location where the device components can be fixedly secured. The device can be embodied as a series of parapet clamp devices with each uniquely adaptable to the environment in which it is deployed.
