OSHA compliant Wrenches we're about to begin aPV installation along the lower edge of a 100 foot long metal building. Because of skylights down the middle of the length of the E-W roof we are forced to mount the southern-most row only about 5 feet from the 20 foot high eave. Fortunately the slope is less than 10 degrees but perimeter warning lines are a must here. Not wanting to appear a cheapskate here but I'm not surprised at the outrageous cost of "OSHA compliant" perimeter warning flag systems. Your basic fold up standards with nothing more than light-weight bases and multi-colored banner rope runs hundreds of dollars. Even sandbags for ballast are way overpriced. So where are the affordable units available or is there such a thing? Better yet, has someone fabricated their own pro-looking standards and used the same off-the-shelf banner rope used in the roofing catalogs? I already have several hundred feet of banner rope just nothing to hang it from.
