          PART 2PRODUCTS
          A.Acceptable Manufacturer: Johnson Architectural Hardware, Div. of C. Sherman Johnson Co., Inc., which is located at: 1 Matthews Dr.; East Haddam, CT 06423; Toll Free Tel: 800-874-7455; Tel: 860-873-8697; Fax: 860-873-8589; Email: request info; Web:
          ** NOTE TO SPECIFIER ** Delete one of the following two paragraphs; coordinate with requirements of Division 1 section on product options and substitutions.
          B.Substitutions: Not permitted.
          C.Requests for substitutions will be considered in accordance with provisions of Section 01 60 00 - Product Requirements.
          D.Provide all cable, materials, fittings and components from a single manufacturer.
          ** NOTE TO SPECIFIER ** Select size of cable and fittings required and delete those not required. 1x19 wire rope is used for most railing applications. 1x19 has higher tensile capacity and is more resistant to bending and deformation under load. Typically 3 mm (1/8 inch) to 6 mm (1/4 inch) is used for cable infill. The fittings and size of cable to be used can be selected by Architect from Johnson product literature and load tables. Contact Johnson for assistance in determining the fittings and correct cable size for your application.
          ** NOTE TO SPECIFIER ** Select the cable size and type required to suit the performance requirements of the project. 3/16 inch cable is typically used for most railing applications. In high traffic applications such as airports, stadiums or amusement parks, 1/4 inch cable is highly recommended. For residential applications where view and unobtrusiveness are paramount, 1/8 inch cable is often used. In addition, heavier cable is recommended in locations where the bottom cable may be subjected to more stress such as conditions when it may be used as a footrest.
          A.Cables: ASTM A 492, Type 316 stainless steel, polished finish, commercial, dry grade.
          ** NOTE TO SPECIFIER ** Select one of the following paragraphs to suit the performance requirements of the project. 1x19 cable is a semi-rigid, low-stretch cable, used for long straight runs and typically used for most rail applications. 7 x 7 cable is a semi-flexible cable used for short runs up to 25 feet and decorative corners. Note that while 7x7 cable is not as sturdy as 1/19 cable it is slightly less expensive. 7 x 19 cable is a very flexible cable similar to winch cable that is not recommended for rail systems and is typically used for decorative purposes only. Typical breaking strength for 1x 19 is: 1/8 inch - 2,100 lbs, 3/16 inch - 4,700 lbs, 1/4 inch - 8,200 lbs, 3/8 inch - 17,500 lbs. Typical breaking strength for 7x7 is: 1/8 inch - 1,700 lbs, 3/16 inch - 3,700 lbs, 1/4 inch - 6,100 lbs, 3/8 inch - 12,600 lbs.
          1.Straight Runs: 1/8 inch (3 mm) diameter, 1x19.
          2.Straight Runs: 3/16 inch (5 mm) diameter, 1x19.
          3.Straight Runs: 1/4 inch (6 mm) diameter, 1x19.
          4.Straight Runs: 3/8 inch (9.5 mm) diameter, 1x19.
          5.Straight Runs under 15 feet: 1/8 inch (3 mm) diameter, 7x7.
          6.Straight Runs under 15 feet: 3/16 inch (5 mm) diameter, 7x7.
          7.Straight Runs under 15 feet: 1/4 inch (6 mm) diameter, 7x7.
          8.Straight Runs under 15 feet: 3/8 inch (9.5 mm) diameter, 7x7.
          B.Fittings: Type 316 stainless steel, vibratory/tumbled finish. Provide fittings required for attachment and connection of stainless steel cable and infill to support framework and substrates.
          1.Cable Attachment Method:
          ** NOTE TO SPECIFIER ** Select one of the following methods of attaching cable to fittings and delete those not required. Machine Swaging is stronger and more aesthetically pleasing where the cable attaches to the fitting but requires a cable fabricator. Hand Crimping is possible only with 1/8 and 3/16 inch cable. Hand Crimping method allows for easy field installation. Mechanical terminals are more expensive and are typically not recommended for guardrails.
          a.Machine Swaging: Machine swaged by cold-forming press, with smooth surface and can achieve full cable strength in fitting connection.
          b.Hand Crimping: Hand crimped for in-field installations.
          c.Mechanical Terminals: Mechanical terminal with full cable strength in fitting connection.
          d.As recommended by the fabricator and approved by the Architect.
          ** NOTE TO SPECIFIER ** Turnbuckles come in many different attachment styles and designs. Metal or wood railing frameworks require careful selection of turnbuckles to ensure a safe and logical railing system. There are many way to achieve the same guard rail goal with different turnbuckles. Select from the following series of turnbuckles and choose the end attachment style that best suits your needs for the type of framework you design. Select one of the following Series of turnbuckles and end attachment styles and delete those not required.
