A pass-through cable grab system which allows a workman wearing a harness to move up and down a ladder on a tower or similar structure while being protected from falling by a vertically extending safety cable attached to the tower. The system includes at least one standoff bracket having a rear end secured to the tower and a forward end secured to the cable. A cable grab assembly includes a housing that can move vertically up and down the cable and further includes a brake mechanism. A lever extends from the housing and is connected to the workman through a lanyard. In the event of a fall, the lever moves downwardly activating the brake mechanism. The housing includes a vertically extending slot which allows the cable grab assembly to pass over the forward end of the standoff bracket as the cable grab assembly moves up and down. The standoff bracket also includes cam surfaces adjacent the top and bottom thereof which engage the housing as it moves toward the bracket to properly align the cable grab assembly so that it can pass over the standoff bracket.
