A temporary guardrail system comprising:
- a plurality of stanchions, said stanchions each having a bottom end and a base having a top side and a bottom side, said base fixedly attached to the bottom end in perpendicular relation thereto, each base having a plurality of mounting apertures extending from said top side to said bottom side;
- each of said stanchions further having an upper and lower bracket attached thereto,
- a plurality of side rails supported by the upper brackets of said stanchions;
- a plurality of side rails supported by the lower brackets of said stanchions;
- each said side rail comprising an outer rail member and a slidable inner rail member whereby the length of said side rails is adjustable;
- said slidable inner rail member further having, when in a fully retracted position, a distal end which protrudes from said outer rail member;
- each of said side rails having an end defining an opening opposing an opening in another of said side rails;
- and,
- a plurality of coupling members, each coupling member having a pair of end sections, each said end section sized to be partially inserted within the opposing openings, each said coupling member further comprising a directional means disposed between said pair of end sections, said directional means capable of positioning the respective end sections of the coupling members partially within the opposing openings of adjacent side rails which are orientated in different vertical and horizontal positions.
