How many rolls of chain link for 300 ft?

Short answer

300 ft of 4 ft chain link takes 6 rolls of fabric, 30 top rails, 2 terminal and 29 line posts, and 33 bags of concrete.

• Fabric: 300 ft ÷ 50-ft rolls = 6 → 6 rolls of 4 ft fabric with nothing to spare — if your measurement runs even a foot over, buy one more roll.
• Posts: 2 terminal posts (2-3/8 in) at least 6' 4" long and 29 line posts (1-5/8 in) at least 5' 6" long, 10' on center.
• Top rail: 300 ÷ 10 = 30 pieces of 1-3/8 in × 10 ft 6 in swedged rail — each swedged end slips into the next piece.
• Fittings: 2 tension bars, 6 tension bands (3 per bar for 4 ft fabric), 2 brace bands, 2 rail end cups, 8 carriage bolts, 29 loop caps, 2 dome caps and 266 ties.
• Concrete: 33 × 50-lb Fast-Setting — 2 per terminal post in an 8-in hole and 1 per line post in a 6-in hole (1,650 lb to haul).
• Add a 48-in walk gate and you need 4 terminal posts, 2 post hinges, 2 frame hinges and a fork latch, and the fabric drops to 296 ft (6 rolls). Bent into a U, the same 300 ft needs 6 tension bars because each corner takes two.
• Fabric, framework, concrete and gravel come to about $2,473 (fabric price estimated) against $3,000–$7,500 installed (Modernize, Aug 2026).
• 4-ft fabric meets CPSC's 48-in minimum for a pool barrier, but CPSC also caps the mesh at 1.25 in square — standard residential mesh is larger, so a pool needs small-mesh fabric or slats.
• 30 top rails at 10 ft 6 in each are long, awkward loads — ask about delivery or plan for a vehicle that can carry 10.5-ft lengths.
