A rotatable power center is configured for installation along a work surface or the like, and includes an outer housing and a pivotable inner housing having one or more electrical or data outlets. The inner housing is positionable between a use position in which the outlets are accessible along the work surface, and a non-use position in which the outlets are generally not accessible. The outer housing defines an upper opening through which different surfaces of the inner housing are exposed or accessible, depending on the inner housing position. Spindles or spindle caps are used to pivotable mount the inner housing to the outer housing, and may also serve to secure two inner housing pieces together. A separate latch may be provided to secure the inner housing at the use or non-use position. Optionally, a detent arrangement holds the inner housing at the use or non-use position.
