Abstract
The fall arrester according to the present invention includes a plurality of upright standards which are spaced apart along the sill plate of a wall of a building under construction. The upright standards extend above the sill plate and netting is attached to the upright members to span the space between adjacent upright standards. A ledge bracket is provided on each of the upright standards which extends inwardly from the wall to which the upright standard is secured. Planks are then placed on the ledge brackets of adjacent upright standards to provide a working platform for workers installing roof trusses and sheathing. At the gable end of the building, a gable-end pole is mounted to a truss and lifelines are installed between the pole and the upright standards to prevent workers from falling from the gable-ends of the roof.
