Pinnacle Rail™
Exceptional Performance. Elevated Design.
Pinnacle Rail takes PVC railing to its highest expression. Reinforced with aluminum for structural integrity and crafted with TimberTech's hidden stainless steel fastener system, every joint is clean, every line is crisp. Choose classic balusters or make a statement with decorative Chippendale or square web panels — design elements you simply can't find in other railing systems.
Decorative Panels
Chippendale and square web panels add architectural character that standard balusters can't match — unique to Pinnacle Rail.
Hidden Fasteners
Discreet stainless steel hidden fastener system ensures a sleek, seamless appearance — no visible screws or brackets.

Pinnacle Rail™ FAQ
What makes Pinnacle Rail different from composite railing?
Pinnacle Rail is made from extruded PVC reinforced with aluminum, delivering the highest moisture resistance of any TimberTech railing. It won't crack, chip, rot, swell, or split — even in the most demanding wet environments. The material produces crisp, milled-wood-inspired lines that composite cannot replicate.
What infill options are available?
Pinnacle Rail offers three infill options: solid square PVC balusters for a classic look, Chippendale Type 1 decorative panels for architectural character, and square web decorative panels for a geometric statement. Decorative panels are available in both 36" and 42" heights.
Is Pinnacle Rail only available in white?
Yes, Pinnacle Rail is currently available in White only. The clean white finish delivers a crisp, traditional aesthetic that pairs beautifully with virtually any decking color.
Can I add a gate to Pinnacle Rail?
Yes. A beautiful, sturdy PVC Rail Gate Kit is available, reinforced with aluminum and featuring a lockable latch system. No cross-bracing needed. Available for both 36" and 42" wide openings.
What heights and lengths are available?
Pinnacle Rail comes in 6-foot and 8-foot sections (72" and 96" actual) in both 36" and 42" heights. Stair sections are also available in matching lengths and heights. Sections are designed to be cut down for on-center post measurements.
