Abstract: An improved bypass device for a fall arrest system that is not impeded by cable supports as it is pulled along a flexible and/or rigid cable. The bypass device has a gate which can be quickly and easily removed from a frame of the bypass device to reveal an opening which allows the bypass device to be positioned on the cable. Once the bypass device is positioned on the cable, the gate may be reattached to the frame to partially close the opening. A portion of the opening remains unblocked by the gate so that the bypass device will pass over one or more cable supports when it is pulled along the cable. The cable supports act to guide the cable along a desired workpath. The supports are also constructed to withstand the force exerted on the cable in the event someone or something connected to the bypass device falls.
