Professional DIY Layout Tips
To ensure a rock-solid structural setup and meet building code standards:
- Post Spacing: We highly recommend a maximum spacing of 4 feet center-to-center between posts to prevent cable deflection.
- Max Section Run: Keep individual cable runs to a maximum of 20 feet (up to 6 posts) before terminating to maintain proper cable tension.
- Coastal Notice: This T304 post is ideal for standard indoor and outdoor environments. For projects within 10 miles of saltwater, we recommend looking into Zylorix SS316 marine-grade posts.
- Grommet Use: Always install the included rubber grommets in the pre-drilled holes to prevent metal-on-metal wear and friction against the tension cables.
