The 500-C Series Cable Railing Kit by Ultra-Tec features a surface-mount configuration, along with two different cable size options, a wide variety of lengths and a design specifically for use on pitched (stair) runs that have wooden posts with composite sleeves with an outside diameter greater than 4½". The tensioning device is an Adjust-A-Body with Threaded Eye, which attaches via mounting screw to the extended lag eye on one end post, while a Push-Lock with Threaded Eye attaches to the other end post. With this kit's 100% swageless design specifically made for DIY homeowners, it will completely eliminate the need for expensive professional installation while also making your deck look great!

Swageless fittings are made to easily be installed by hand in the field, requiring only the use of Cable Cutters. By using swageless fittings, the holes that need to be made only need to be as big as the bare cable that passes through. This also eliminates the use installers or expensive machinery because it can all be done by hand in a matter of minutes.

Surface-Mount configurations are the only types of installations that the 500-C Series can be used with. Surface-Mount installations create an organized, clean look while also serving as a secure means of installing your cable railing in situations where the back of the post is inaccesible. The 500-C Series should not be used on corner installations because it is not recommended to bend cables through a sleeved post, therefore stair to landing installations need to be on two seperate runs.

Wood Post Installations

For wooden posts, a minimum outside diameter of 4½" is required to keep the post from bending when cables are tensioned. A top rail is also needed and is recommended that it be reinforced with a support such as a 2" x 4" on end under the top rail. End posts must also be securely mounted to the deck in order to prevent the post from coming loose while tensioning cables. Additonally, a bottom rail is recommended to to help distribute the force away from the bottom of the post, however it is not required.

Intermediate Posts

Intermediate posts (or mid-posts) are to be placed every 48" between end posts. An intermediate post runs from the top rail to the lower mounting surface and is integral for proper structural design. Intermediate posts can be substituted with something thinner such as an aluminum or steel cable brace. Cables are strung through holes in each post in order to provide support between end posts. Each post hole made should not exceed 3" vertical spacing in order to comply with IBC regulations. Cable Braces can be purchased here.

Cable Runs On A Pitch

Top posts are often corner posts, which may often require the stair run to connect to the face of the post. The top and bottom of the cable run should be connected perpendicular to those posts, and only the intermediate posts would be drilled on the angle for the cables to run through.

Tools Needed For Installation:

  • 5/32 Drill Bit For 1/8" Cable / 7/32 Drill Bit For 3/16" Cable
  • 9/32 Drill Bit For Lag Eye Installation
  • 7/16 Wrench For Tensioning Adjust-A-Body
  • 5/32 Hex Wrench To Tighten Mounting Screws
  • Cable Cutting Tool

*In order to comply with IBC regualtions, an intermediate post must be placed every 48" between posts and distance between each cable shall not exceed 3", however specific city and state rules and regulations may apply.
