   "Beyond the 1-5/8 in channel (strut-channel-1-5-8 page, which already draws the 7/8, 13/16, 1, 1-3/8, 2-7/16 and 3-1/4 in tall profiles and the 3-1/4 in back-to-back), Unistrut also sells a 1-1/4 in wide 'A series' and a 13/16 in wide light series. Part numbers, heights and gauges are from Unistrut Ohio's channel-size table; * means special order (P3000 low volume). Back-to-back sections (last digit 1) are two channels welded back to back.",
   "13/16 in channel is 19 gauge, 0.040 in (1.0 mm) thick; its slot, flange and lip are NOT given in any text read.

The 1-5/8 in x 13/16 in, 16 gauge (P4000) profile is the one the strut-channel-1-5-8 page says prints different flange numbers; those numbers were not found either.",
   "Section properties read from Unistrut's own product pages: P4000 (area 0.244 in², weights 0.82 lb/ft pre-galvanized to 0.869 hot-dip) and P6000 (area 0.107 in²). Hole and slot patterns on these pages: 'punched holes are also available', no sizes.",
