Manufactured gates shall be 18 feet long x 51-1/2 inches high, constructed of 15 gage, 1-1/2 <br /> inch square tubing similar in quality to the "Heavy Duty Cattle Gate" as manufactured by Linn <br /> Enterprises, Linn, Kansas 66953, except that a 1-1/2 inch x 1-1/2 inch x 2 feet 2 inches long <br /> solid steel bar shall be continuously welded onto the gate for a gate latch as shown on Standard <br /> Drawing Number 9. (These gates shall be furnished with all necessary hinges and <br /> appurtenances.) The gate shall have at least one finish coat of green enamel so as to match <br /> standard steel fence posts. <br /> Steel pi used for framing the lock chambers, for manufactured gates, shall be standard weight <br /> (Schedule 40) seamless steel pipe. <br /> 18.3 EXECUTION <br /> Line Posts <br /> Steel line posts shall be driven 1-1/2 feet into the ground or to the top of the anchor plate. All <br /> posts shall be set to the minimum depths specified above unless bedrock or other restrictive layer <br /> prohibits it. In such cases, line jacks or other suitable type of anchoring shall be acceptable, or <br /> posts may be set in pre-drilled holes at least twelve inches (12") deep and backfilled with <br /> concrete. Line posts shall be spaced uniformly, as shown on Standard Drawing Number 9. <br /> Wooden line posts shall be inserted into a hole dug a minimum of 28 inches deep. The backfill <br /> material must be thoroughly compacted by tamping so that the installed post has minimal play. <br /> Maximum wooden post spacing is twenty feet (20') for a 4-wire fence, and eighteen feet (18') <br /> for a 5-wire fence. <br /> Fence shall be straight between corners. Some tree branch or brush cutting may be required to <br /> maintain alignment. Reasonable deviation in alignment will be permitted where rocky ground <br /> or steep slopes make it necessary. <br /> Corner Post <br /> Unless otherwise specified, comer post installations in conformance with Standard Drawing <br /> Number 9 shall be installed at all comers and at all points where the fence alignment changes <br /> horizontally fifteen degrees (15°) or more. <br /> End Post With Brace <br /> End posts with braces shall be built as shown in on Standard Drawing Number 9 at both sides <br /> of all wire gates, at all fence ends, and where fences cross large water courses or below rock <br /> structures as shown on Standard Drawing Number 9. A twelve-inch by twelve-inch by twenty <br /> four-inch (12" x 12" x 24") concrete block or durable rock of equal size may be used as a <br /> deadman anchor in lieu of braces to fit site conditions. <br /> Line Braces <br />
