Abstract: An improved mounting device and assembled configuration for deploying a manually operated pullout shade system of the type having a tensioned roller member carrying a flexible canvas sheet and parallel tubular actuators therefor. In one embodiment of the present invention, a mounting device is disclosed for securing the manual pullout shade system onto an arching tubular overhead structure onboard a boat so that the pullout shade may be adjusted in its working attitude and maintained in proper position for deployment. The mounting device includes a set of clamp members each constructed in the form of a figure “8” with associated circular sections on each clamp member being rotatably coupled together.
