8 feet
10 feet
12 feet
Rail heights come in 36 inches and 42 inches, so you can match local code and your design preferences. Keep in mind that nominal lengths can differ slightly from finished, installed dimensions once posts and hardware are factored in.

Yes. Drink Rail is one of the top rail options available with the Classic Composite Series, and it's a favorite for entertaining. It gives you a wide, flat surface, perfect for setting down a drink or a plate while you enjoy the view.
The Classic Composite Series actually offers several top rail profiles, so you can dial in the exact look you want:
Drink Rail
RadianceRail®
Premier Rail
Trademark Rail™
Yes, with the right approach. The Classic Composite Series is a durable, low-maintenance railing that performs well in a variety of outdoor settings, including near lakefronts and pools.
For salt-water and coastal projects, a few smart steps go a long way:
- Always check local code requirements for coastal applications
- Use corrosion-resistant hardware suited to salt air and spray
- Keep in mind that the TimberTech Limited Warranty does not cover exposure to corrosive elements.
