Abstract
A horizontal safety net support system which is especially adaptable for high-rise building renovation projects employs a collapsable wind brace and a retractable support arm section. The wind brace includes a pair of restraining tubes which are pivotally connected and are maintained in a linear configuration under the force of a spring. A pre-established force applied to the wind brace will result in the wind brace folding to a collapsed position to permit erection of the support arm for cleaning or installation purposes.
