Abstract: An improved pipe shoe is provided for permanently supporting a length of insulated pipe above a pipe rack of the type used in industrial facilities. The pipe shoe includes a base member for sliding engagement with the pipe rack, a first clamp member including a spacer portion, a first clamp portion, and a through slot. A second clamp member includes a second clamp portion and a projecting plate, such that the plate can be fitted within the through slot and the second clamp member rotated to its closed position. A securing member retains the plate adjacent the spacer portion, so that adjacent edges of elongate insulation members may be positioned on opposing sides of the spacer portion and the adjacent plate. The insulation thus retains its generally sleeve-like configuration about the pipe and the pipe shoe, thereby decreasing the time required to install the insulation.
