The frame is particularly adapted to be used with Optical Fiber Composite Ground Wires (OPGW) and has a coiling chamber for the coiling of the surplus splice length. The coiling chamber has an interior in which the surplus splice length is coiled, and an outer edge, allowing the free rotation of the frame about a shaft. The surplus splice length is pushed from underneath by an operator and is further pushed and held by its own restoring force against the outer edge of the coiling chamber, where the pushing and holding effects induce the rotation of the frame.
