CHAIN LINK FENCE MANUFACTUTERS INSTITUTE PRODUCT MANUAL(CLF‐PM2445)The purpose of this manual is to provide chain link fence technical information for general knowledge,system design or the development of a commercial/industrial/security chain link fence specification.HOW TO USE THE CLFMI PRODUCT MANUALa. Familiarize yourself with the content of the CLFMI product manual.b. The product manual includes drawings of the four standard chain link fence designs plus swinggate, cantilever slide gate and fitting/assembly details.c. Review the different chain link fabric configurations and gauges to ensure the best selection ofthe mesh size and wire gauge for the application.d. Prior to designing a security fence system read the CLFMI “Security Fencing RecommendationsSFR2445”.e. Select the type of fabric for the application; galvanized (ASTM A392), aluminum coated (ASTMA491), zinc ‐5% mischmetal alloy (ASTM F1345) or polymer coated (ASTMF 668).f. Review the framework Dimensions and Strength Characteristics Table # 6 and Guide forSelection of Line Post, Table # 7 to select the post that best suits the application, (ASTM F1043and ASTM F1083). Make sure to take into consideration wind load particularly if the fence is 8 ft.high or greater using 1 in. mesh or less. Use the CLFMI “Chain Link Fence Wind Load Guide forthe Selection of Line Post and Line Post Spacing WLG2445” for a fence requiring a structuralframework design due to wind load.g. For polymer coated fabric or systems choose an ASTM color from ASTM F934.h. Thoroughly review and understand the chain link ASTM standards; those reference above aswell as; chain link terminology (F552), fittings and tie wire (F626), barbed wire (A121 and F665),barbed tape (F1910 and F1911) tension/coil spring wire (A824 and F1644), swing gates (F900),horizontal slide gates (F1184), automated vehicular gates (F2200), and chain link installation(F567).i. The CLFMI manual includes a CSI formatted chain link fence specification, “Commercial,Industrial and Security Chain Link Fence and Gates, Section 32 31 13” for use in designing andspecifying a chain link fence system.j. For light industrial/commercial applications select framework form ASTM F1043 Table 4“Summary of Requirements for Light Industrial/Commercial Fence Framework”.k. All phases of chain link fence installation are covered in detail within the Specification 32 31 13,Part 3.1

DESCRIPTION OF TERMSA short list of descriptive terms: (See ASTM F552, “Standard Terminology Relating to Chain LinkFencing” for a complete list.)a. Chain link fabric – A fencing material consisting of wire helically wound and interwoven in such amanner as to provide a continuous mesh without knots or ties except in the form of knuckling ortwisting at the top and bottom of the mesh to form the fabric selvage.b. Selvage‐The top and bottom edge finish on woven chain link formed by joining adjacent pairs ofwire pickets. The selvage may be knuckled or twisted.c. Knuckled selvage* refers to bending the adjacent pairs of wire back into a tight loop.d. Twisted selvage* refers to twisting the adjacent pairs of wire together in a close helix of 1 ½machine turns, which is equivalent to three full twists.e. Mesh size – The minimum clear distance between the wires forming the parallel sides of themesh.f. Terminal post – A post to which the chain link fabric is terminated using specific fittings; endpost, corner post, gate post and pull post (a terminal post used to accommodate a grade orplaced at intervals on long stretches of fence).g. Line post‐ Intermediate posts set no greater than 10 feet on center between the terminal posts.h. See drawing Typical Fence Section for details of various fence fittings; tension bar, truss rod,tension band, brace band, rail end and barb arm.KNUCKLE SELVAGE*TWIST SELVAGE**Adapted, with permission from the Annual Book of Standards, copyright ASTM International, 100 Barr Harbor Drive, West Conshohocken, PA192482
