主权项 1. A fall arrest safety net arrangement for securing an overhead fitting device, the fall arrest safety net arrangement comprising: a wire mesh bag having an open mouth and a closed end, the wire mesh bag constructed of wire strand having a first thickness and formed by joining adjacent portions of the wire strand and forming a plurality of eyes spaced circumferentially about the mouth; a slit in the wire mesh bag extending from the open mouth toward the closed end, the slit separating a first length of the wire strand and a second length of the wire strand from one another, the second length of wire strand adjacent to the first length of the wire strand; an elongate line having a second thickness greater than the first thickness of the wire strand, and having: a first end,a second end spaced apart from the first end, andan intermediate portion located between the first end and the second end and extending through the eyes spaced circumferentially about the mouth; a choker fitting having: an upper surface,a lower surface,a plurality of line accepting apertures extending between the upper surface and the lower surface of the choker fitting, andan end fixture having a first end accepting aperture extending between the upper surface and the lower surface of the choker fitting and spaced from the plurality of line accepting apertures, wherein the elongate line extends through at least one of the line accepting apertures; and at least one wire mesh extent adjustment comprising an auxiliary wire having a first end and a second end secured to a first section of the wire strand to define a mesh strand accepting space opening between the auxiliary wire and the first section of the wire strand, and a toggle on a second section of the wire strand, sized to selectively prevent a portion of the second section of the wire strand from exiting the mesh strand accepting space opening.
