How to Install Signature Series Top Mount Cable Rail Posts

  • 3 min read

Installing Signature Series Top Mount Cable Railing

Watch this short demo video for step-by-step instructions on installing Signature series top mount posts.

How difficult is this project?

This project is: DIY-friendly - Advanced

Installing Signature Series posts and cable rail tensioners on level runs is straight-forward. Take special care to consider your post layout around stairs. Advanced carpentry skills may be required for complex handrail joints. Consult an experienced metal worker when installing stainless steel handrails.

Signature series top mount posts with cable railing infill are a beautiful addition to any deck, patio, or staircase giving you a cleaner, unobstructed view. If properly maintained, all-metal railing can provide a lifetime of beauty and reliability.

Depending on your project layout and specifications, installation can vary from DIY-friendly to advanced skill level required.

Installation Instructions

1| Project Guidelines

  1. Cable tensioning posts can be spaced up to 20 feet apart. To ensure adequate cable tension (150#) use 2-way posts and additional tensioners to cover longer runs.
  2. Add cable spacer bars or cable support posts every 42–48 inches to minimize cable deflection under load.
  3. Support your handrail as needed with tensioning posts. See Setup Guide for post spacing recommendations.

PLEASE NOTE: All Cable Bullet recommendations and rail components are designed to comply with the International Residential Code (IRC). However, because building codes may vary it is the installer’s responsibility to verify that the installed system complies with all applicable state and local building codes. For more information on Cable Bullet and building code standards, visit our terms page.

2| Mark Post Location

Mark the location of each structural screw

Determine the placement of your posts, and mark the location of each structural screw (4 per post).

PRO TIP: Use painter's tape to mark the edge and angle of your posts.

3| Drill Pilot Holes

drill 4 pilot holes

Set your post aside and drill four pilot holes with the 3/16" drill bit. The depth of your pilot holes will vary by project and foundation construction.

4| Set Mounting Screws

set the mounting screws with a drill

Set each screw, but don’t tighten them down before levelling the post. Screw lengths and type will vary by application (see Setup Guide for structural guidelines). It is the installer’s responsibility to ensure there is sufficient blocking to anchor securely to!

5| Advance Screws

tighten the set screws with a 3/16

Use 3/16” Allen wrench to advance the four set screws to plumb your post, then finish setting each screw. Repeat the process until all structural posts are set.

PRO TIP: The leveling feature is designed to work best on hard surfaces. On soft wood or composite decks, consider adding a #10 washer underneath each set screw.

6| Attach Your Top Rail
