(2) Depth. Depth shall be a minimum of twenty-four inches (24") for a four-foot high fence, plus an additional three inches (3") for each additional one foot increase in height over four feet.
(3) Top rail. A top rail shall be used for all chain link fences. Top rail shall be continuous between terminals and shall be swedged or sleeved. Top rail shall be supported at all posts. At corners and terminals, rail shall be connected by means of a rail end fitting.
(4) Dimensions of structural members.

Rolls of wire fabric shall be joined by weaving a single picket into the ends of rolls to form a continuous mesh. Fasten fabric to line posts at intervals not exceeding fifteen inches (15"). Fasten fabric to top rail at intervals not exceeding twenty-four inches (24"). Tension bars shall be used at all terminal, corner and gate posts.

For non residential applications, minimum gauge of chain link fence fabric shall be 9 gauge.
