Under the Caltrans specification, what is the diamond count for chain-link fabric 60 inches high?
Why: The table gives 17-1/2 diamonds for 60-inch fabric. Twenty and a half is the 72-inch count, 13-1/2 is the 48-inch count, and 24-1/2 is the 84-inch count.Caltrans 2024 Standard Specifications 80-3.02C
A crew is laying out a long chain-link run with a gate, two corners and two ends. Which posts are located first?
Why: Terminal posts (end, corner and gate) carry the pull of the fabric or the weight of a gate, so they are located first and the line posts are spaced between them. The line posts nearest the gate depend on where the gate falls, and mid-run posts and the easiest holes to dig would leave the spacing to chance.Chain-link maker installation guide
