Structural Support with a Minimal Footprint

The Cable Bullet intermediate post is a sleek, top-mount, structural pass-through post, designed to support both your cables and top rail, with the smallest visual footprint possible.

Intermediate posts are made from solid T6061 tempered aluminum for maximum yield strength. Each post includes pre-drilled cable pass-through holes every 3 inches on center, optimally sized for use with 5/32" diameter cable (max.). The elongated, tapered hole design offers the necessary support on level runs, while still allowing the cable to pass through without kinking along sloped spans.

Combine these posts with Signature series side mount tensioning posts, or add them as infill for custom side mount wood railing. Use cable spacer bars to maximize the view from your deck, patio, or stairway.

    What's included with each post?

    Each Signature series intermediate post includes the following components:

    • (1) Post
    • (1) Handrail mounting bracket
    • (4) Post-leveling set screws
    • (2) Screws to mount the column to the mounting bracket

    What tools & supplies will I need to install my posts?

    For detailed installation instructions and setup guides, see the Helpful Guides & Resources list on this page.

    PLEASE NOTE: Aluminum posts and handrail are NOT suitable for use in exterior coastal applications. Signature series railing is designed for inland exterior and interior projects. Exposure to salt will cause accelerated oxidation and galvanic corrosion between aluminum and stainless components.
