Inside of Wood Post to Inside of Wood Post Cable Rail Kit by Rail FX
What It Is
The 300 Series by Rail FX is a stainless steel cable railing kit designed for straight, inside-of-post cable runs — especially in wood railing applications. It’s one of RailFX’s classic cable kits and is meant to give you a sleek, modern infill option that’s relatively easy to install and durable for outdoor decks or balconies.
Key Features
Mounting & Compatibility
- Inside-of-post to inside-of-post mount: The cable runs straight through drilled holes in your posts, so the fittings are mostly concealed.
- Best with wood posts: Intended for minimum 4×4 wood end posts, though it can be adapted to other setups with the right fittings.
- Straight cable projects: Ideal for level runs (not pitched/stair sections).
Hardware & Materials
- Adjust-a-Body® tensioner: Screws into one post to tension the cable.
- Push-Lock® Lag fitting: Secures the cable on the opposite end.
- 1/8″ Type 316 stainless steel cable and fittings: Excellent corrosion resistance, great for exterior use.
- Made in the USA and designed for long-term outdoor performance.
Length Options
- Cable runs in the 300 Series are available in a range of lengths (e.g., 5 ft to 50 ft) so you can pick based on your deck or balcony span.
