Claim:
1. A fitting for channel framing having a first side defining a continuous slot extending into an interior of the framing, and a second side defining an external fitting groove, the fitting comprising: a coupling component, at least a portion of the coupling component having a generally dovetail cross-sectional shape defined by an outer perimeter of the coupling component configured for reception in the external fitting groove of the channel framing, wherein the coupling component defines an opening sized and shaped to receive a fastener, wherein the coupling component has a lower face, an upper face, opposite sides, opposite ends; a groove defined by one of the opposite sides of the coupling component and extending from the upper face toward the lower face; a washer secured to the coupling component and configured to engage outside surfaces of the second side of the channel framing at opposite sides of the external fitting groove when the coupling component is received in the external fitting groove, wherein the portion of the coupling component having a generally dovetail cross-sectional shape defined by the outer perimeter of the coupling component tapers toward the washer, wherein the washer defines a through opening that is generally aligned with the opening defined by the coupling component and sized and shaped to receive the fastener; a coil spring interposed between the washer and the coupling component and securing the washer to the coupling component, wherein the coil spring biases the washer in a direction toward the coupling component, the coil spring including an upper extended portion firmly fixed to the washer, and a lower extended portion firmly fixed in the groove defined by one of the opposite sides of the coupling component, wherein the washer is movable in a direction away from the coupling component to resiliently deflect the spring.
