Unistrut channel series: 1-5/8 in (P1000 to P5500, back-to-back), 1-1/4 in A series and 13/16 in P6000 / P7000: sizes and gauges — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/strut-channel-series-1-5-8-1-1-4-13-16/ (sheet CC BY 4.0) Basis: Unistrut Ohio channel-size table, Unistrut product pages (P4000, P6000), Unistrut Store 13/16 page; no profile dimensions were readable for 1-1/4 and 13/16 series Catalog version: 2026-10-20 Sizes: see table below - 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 only drawing found (P7000 in a distributor catalog PDF) came back as unlabeled numbers (7/16, 3/16, 3/16, 13/16, 3/32, .243, .163, 13/32) that could not be assigned to features, so no 13/16 or 1-1/4 profile is drawn. 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. - Eaton B-Line equivalents (B52, B54 for 1-5/8 x 13/16) are on the strut-channel-1-5-8 page.
