Wire rope sizes and weights: 6×19 IWRC and fibre core, 7×7, 7×19, 1×19 — diameter in inches and mm, weight per foot — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/wire-rope-sizes-6x19-7x19-1x19-weights/ (sheet CC BY 4.0) Basis: Unirope, Sky Dog Rigging and Lexco Cable for 6×19 weights per foot; Campbell's galvanized cable table for 1×19, 7×7 and 7×19; numbers only, breaking strengths left out on purpose Catalog version: 2026-10-20 Sizes: see table below - Diameter is the nominal rope diameter in inches as each source prints it (measured across the outer crown of opposite strands, which the Campbell catalogue states); the mm column is that diameter converted (× 25.4, computed). Weight is as printed: pounds per foot (6×19 sources) or pounds per 1000 ft (Campbell); the last column converts each to pounds per 100 ft (computed). Metric kg/m is not given by these sources. - 6×19 construction is six strands of 19 wires (the class covers 6×19 Seale, Filler wire and others, so the number of wires per strand varies inside the class); IWRC is an independent wire rope core, FC a fibre core; 7×7 and 7×19 are seven strands (one core strand and six outer strands) of 7 or 19 wires, 1×19 is a single strand of 19 wires. These are general definitions; the sources read do not tabulate wire diameters or lay lengths, so none is shown. - The 6×19 IWRC weights disagree between makers by a few percent, and by more at some sizes: 1/2 in is 0.44 lb/ft (Unirope) against 0.46 (Sky Dog); 5/8 in 0.69 against 0.72; 3/4 in 0.99 against 1.04; 1 in 1.76 against 1.85. Unirope's fibre-core column is lighter than its IWRC column at every size, as expected. The Lexco stainless 6×19 IWRC weights agree with Sky Dog's galvanized figures at 1/2 in (0.458 and 0.46), 5/8 in (0.715 and 0.72) and 1 in (1.87 and 1.85) but differ at 3/4 in (0.922 against 1.04) and 7/8 in (1.430 against 1.56); no source explains the spread. All are shown as printed. - Campbell's 1×19 galvanized row for 1/16 in printed 0.85 lb per 1000 ft, which is inconsistent with the 3/32 in row (20.0) of the same table, so that row is not shown; the 1×19 rows from 3/32 up, and the 7×7 rows from 1/16 and 7×19 rows from 3/32, are kept as printed. Campbell's own note: breaking strengths are for comparison only and operating loads should respect the design factor; breaking strengths, minimum breaking force grades and safe working loads are left out of this page on purpose, because they depend on the rope grade (IPS, EIPS, stainless) and lay. - No file: a rope is a helix of strands whose wire sizes and lay length are not in the tables read, so a drawn rope would be invented.
