Temporary and long term guard rail systems for use by residential and commercial builders on construction sites to prevent accidental falls that can result in serious bodily injuries. The systems meet the standards of fall protection as specified by OSHA including those on safety issues concerning protrusions that can cause lacerations and present clothing snag hazards. The system includes a plurality of vertical posts/stanchions having side rail mounting points that do not present laceration and clothing snag hazards. The posts/stanchions include rotatable collars with internally threaded holes that create mounting points for the side rails that are capable of rotating along the Y and Z axes of the posts/stanchions allowing the interconnection of horizontal guardrails. The side guardrails can include telescoping tubular adjustable lengths or have a fixed length. The adjustable version can be locked at selected lengths with an internal mechanism leaving no protrusions along the exterior of the horizontal length. The temporary/long term guard rail system can be used on balconies, elevated platforms, stair cases, and the perimeter of a floor prior to the external walls or permanent protective railing being erected to prevent accidental injury. Expandable and fixed length toeguard boards can run between posts/stanchions. The system can include load distribution support plates beneath each of the posts/stanchions that eliminate the need for tiedown straps. The support plates can include drainage holes to eliminate water buildup within the posts/stanchions. Mount plates can be used that can connect the system to existing flat wall and corner wall surfaces. The combination of inexpensive long term posts/stanchions and fixed length guard rails with the extremely versatile pivot stanchions and adjustable length guardrails, make this system a highly versatile safety device which is easy to install, easy to dismantle, and relatively inexpensive to manufacture.
