  • Quality, strength, & durability

    Cable Bullet tensioning posts are high-quality, surface-mount posts that are pre-drilled and tapped to accept Cable Bullet tensioners. Heavy-duty 1/4-inch thick aluminum walls, super-durable flat black powder-coating, and machined stainless steel tops give these posts a custom, premium look and feel that stands out.

    Combine Cable Bullet tensioning posts with ultra-slim structural intermediate posts and cable spacer bars for a modern, unobstructed view from your deck, balcony, or stairway.

    Every tensioning post automatically includes a base cover plate and the same set screw leveling mechanism designed for irregular hard surfaces, including concrete or stone patios. Cable Bullet tensioners are sold separately. Mounting screws for the base and top rail are not included and will vary by project.

    Fixed or Pivot Top?

    Each Cable Bullet post features a stainless steel top of your choice that can be fastened to wood or metal top rail. Select the classic fixed-top anywhere you handrail makes a level pass over the post. The classic pivot top is available for select stair applications. To learn more about which post top is right for your project, download: Stair Rail Design: Post Layout & Handrail Options (PDF).

    Selecting the Right Post Type & Height

    Posts are available in 36 and 42-inch heights. 36-inch posts are designed for 11 cable runs, 42-inch posts for 13 cable runs. All tensioner holes are pre-drilled and tapped every 3 inches on center and will accept Cable Bullet tensioners.

    Corner posts have two sets of holes on perpendicular sides to each other (90 degrees). 2-way posts have holes on parallel sides. Ends posts are pre-drilled and tapped on one side only.

    All post holes are set every 3 inches on center.

  • Installation


    • Drill and bits appropriate for anchoring end or intermediate posts to your selection of top rail and flooring
    • (4) Structural screws for mounting each post (sold separately). Screw length may vary by application (e.g. 5/16" x 5-1/8” GRK structural screws for decks with the recommended 3-1/2" blocking). 
      NOTE: When mounting to a concrete foundation, use 1/4" x 3-1/4" Hex Head Tapcon screws. In lower-quality concrete, consider an epoxy anchor or very long wedge anchors.
    • (4) Screws to attach the post top to the handrail. For wood handrail, we recommend Grip Fast #9 Trim Head Screws (length will vary by handrail thickness). For attaching Signature Series Reinforced Aluminum Handrail, use Grip Fast #8 x 3/4" Phillips Flat Head Stainless Steel Sheet Metal Screws.
    • 1/4" Tamper-Proof Security Spanner Nut Bit (sold separately)
    • 3/16 Hex Wrench

    Structural Guidelines

    The structure supporting your posts must be able to handle the transferred loads of the railing system (+150 lbs of tension per cable). It is the installer’s responsibility to make certain that the structure your posts are fastened to is capable of supporting the applied loads.

    Handrails are also a structural component of cable railing and must be able to resist both the compression load of the tensioned cable and perpendicular guardrail loads.

    For more information, please read our terms of service.

    Select your post locations

    When designing your railing layout, follow these guidelines.

    • For optimal tensioning over time, end posts should be spaced no more than 20 feet apart
    • To minimize cable deflection, add Cable Bullet spacer bars or intermediate posts every 3-½ to 4 feet
    • Add structural intermediate posts to support your handrail where necessary
    • Start and stop cable runs at sharp turns (e.g. 90 to 180-degree angles)

    Setting your posts

    Once your post locations have been identified, mark and drill pilot holes for the post-mounting lag screws. Angle each post according to your cable runs before securing them. Before tightening the lag screws, plumb each post using the leveling set screws at the base. Once your posts are secured, set the base cover plate.

    Attaching your top rail

    Use the ¼” Spanner Nut Bit to loosen the two threaded pins on either side of the stainless steel post top. Once your top rail is set, mark and drill pilot holes for each top mount. Secure the top rail, then tighten the threaded pins.

    Note: To ease the installation of the top rail you may detach the u-shaped top-mounting bracket from the post top completely by removing both threaded pins. Detaching and installing the top-mounting bracket is especially helpful when installing a top rail on sloping runs, or where spacing is tight.

    Your posts are now ready for cable infill. Complete this process using the Cable Bullet Metal Post Installation Instructions.
