摘要： The present invention is an improved construction perimeter guard stanchion. A dual adjustment system performs both coarse and fine adjustments to tightly clamp a pair of jaws at the lower end of the stanchion upon the edge of a floor slab in an elevated, unfinished building structure. A coarse jaw adjustment sleeve formed of a short section of hollow steel tubing is coaxially disposed about an outboard support member in sliding engagement therewith. The coarse adjustment sleeve has one or more perforations therethrough so that a locking pin can be passed through it and through aligned openings in the outboard support member. A fine adjustment screw member is disposed coaxially within a vertical rail support tube and may be rotated by lever arms to move the upper jaw closer to or further from the lower jaw. Adjustment of the fine positioning mechanism is performed by manipulating handles at the top of the vertical rail support tube. A workman installing the stanchion thereby does not have to stoop over to operate a clamp located down near the concrete slab.
