Frequently Asked Questions

What is the actual length of TimberTech Pinnacle Railing?

Pinnacle Rail® comes in two panel sizes to fit a range of layouts:

6 feet

8 feet

You can also choose between two rail heights, 36 inches and 42 inches, so you can match local code and your design. Pinnacle Rail ™ actual lengths are out of the box to be cut down for an on-center measurement depending on the post sleeve dimension and/or stair angle.

Pinnacle Level 6′ and 8′ sections (72″ and 96″)

Pinnacle Stair 6′ and 8′ sections (72″ and 96″)

Is Drink Rail compatible with Pinnacle Railing?
Pinnacle Rail® is built around a single, wide, flat top rail with a milled-wood-inspired look. That broad, flat surface already gives you a handy spot to rest a drink or a plate while you enjoy the view, so it delivers a similar everyday benefit to a dedicated Drink Rail.
Which decking collections are compatible with Pinnacle Railing?
Good news: Pinnacle Rail® pairs with every TimberTech Decking collection. Whether you're building with Advanced PVC or Composite boards, this PVC railing works with your deck.
Which lighting options are compatible with Pinnacle Railing?
Pinnacle Rail® can be paired with TimberTech deck and rail lighting to add ambiance and help improve visibility after dark.
Can Pinnacle Railing be used near water? Near salt water?

Yes. Pinnacle Rail® is made from durable, low-maintenance PVC with an aluminum-reinforced core, a combination that's a smart fit for waterfront settings like lakefronts and poolside.

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

What colors are widely available? Are there local exclusions?

Pinnacle Rail® comes in one clean, versatile color:

White

As with any building product, local inventory can vary by length and distributor demand. For exact regional availability and lead times, check with a local TimberTech dealer before finalizing your build.
