Abstract: A load indicator for use with a fall protection apparatus having a line and a connector for connecting to a user includes a housing having a pass-through opening and a covered indicator region. At least a portion of the housing is configured for connecting to the line. The load indicator also includes a shear pin supported by the housing and extending across the pass-through opening, and a saddle extending across at least a portion of the pass-through opening and supported by at least a portion of the shear pin. The saddle is configured for connecting to at least a portion of the connector. The saddle is movable relative to the housing between a first position and a second position when a force exceeding a predetermined threshold value is applied on the saddle causing the shear pin to shear or break. At least a portion of the indicator region is uncovered in the second position of the saddle when the shear pin shears or breaks.
