|Wood Frame Requirements
Railing frames need to be designed and built strong enough to support the tension of properly installed
cables, which is a load in excess of 300 lbs for each cable. Here are some basic guidelines to help you properly prepare
your railing frames. These guidelines apply whether you are using 1/8'', 3/16'' or 1/4'' cable (1/4'' cable not
recommended for wood frames).
- Space cables no more than 3 inches apart
- Space posts/verticals no more than 3 feet apart
- Observe minimum end/corner post sizes shown above
- Securely fasten all posts and cap rails
- Carefully plan all termination and corner posts for proper clearance, positioning, and maximum cable run lengths
- Straight runs of cable (no turns/dips) should not exceed 70 feet; runs with corner bends (2 bends at most) should
not exceed 40 feet
- For railings we recommend spacing the cables no more than 3 inches apart and placing posts or vertical members
no more than 3 feet apart.
- Please note that since building codes vary by state, county and city, our recommendations may not comply with code
requirements in all areas.
- Always consult with your local building department before starting your project.
