US Patent 7802773 Reusable fall restrain supports and fall arrestor

A system for providing re-usable safety support fences and fall restraints for the construction industry. The system comprises a plurality of disposable bases which are welded to I-beams or otherwise permanently attached to a floor or roof, and a plurality of removable support posts that screw into the disposable bases. The support posts form the posts of a safety fence through which steel cables are threaded to form a fence. Also, a fall arrestor, comprising an eye hook onto which a construction or maintenance worker on the perimeter of a building may attach, can be screwed into the permanently mounted disposable base. Additional embodiments for use with concrete construction instead of steel I-beams are disclosed.
