Abstract
Abstract A low-cost, movable guardrail post especially adapted for temporarily supporting safety railings during roofing work and the like is provided which is braced against unintentional tipping for insuring that the integrity of the safety railing is maintained at all times. In preferred forms the post includes a concrete base having an upright steel post member detachably mounted thereon, with a pair of elongated bracing arms connected to the assembly and extending to a point adjacent the support surface and being coupled to a pair of metal stick clips secured to the support surface; in this manner the posts can be quickly mounted adjacent a roof edge, for example, by partially burying the stick clips under a layer of roofing asphalt or pitch and operatively coupling the brace members thereto. When the roofing work is completed, the guardrail posts can be removed by trimming the upstanding portions of the stick clips and transporting the concrete blocks and posts to another work site.
