ABSTRACT:
A roof perimeter cable guard system has a main stanchion member supported at its lower end by an anchor bracket screwed to the roof perimeter. A main brace member extends outward and downward from the upper end portion of the main stanchion member and curves around and under the perimeter feature. The main brace has a lower sleeve receiving an adjustable wall-engaging member to provide bracing against the wall of the structure. In one configuration the wall-engaging member has an additional supporting extender member, which allows the wall-engaging member to engage the soffit of an overhang. An inward extender member and parapet engagement bracket allow for position attachment to a parapet feature. Pairs of barrier cable engagement brackets having barrier cable receiving slots are spaced along the inner side of the stanchion vertical members for easy insertion or removal of an equal number of barrier cables, normally three.
