Westbury Stair Crossover Kit & Post Adapter

The Westbury Stair Crossover Kit & Post Adapter is designed to create a continuous, graspable top rail along stair sections where a standard post would normally interrupt the railing. By replacing the cap on a 2" x 2" Westbury stair post, the crossover adapter allows the top rail to pass smoothly over the post for a cleaner appearance and improved safety on long stair runs. The adapter swivels from 0 to 43 degrees, making it ideal for a variety of stair angles and configurations. Constructed from durable, powder-coated aluminum, the Stair Crossover Kit is built to match Westbury Tuscany and Montego aluminum railing systems while resisting rust, corrosion, and fading. The kit is easy to install and includes the crossover bracket hardware needed to convert an existing stair post into a crossover post, creating a seamless railing transition without gaps. Westbury Stair Crossover Kit & Post Adapter is available in coordinating Westbury finishes to match your railing system and is compatible with both level and stair crossover applications. The adapter is commonly used with 2" Westbury posts and Tuscany stair rail kits to complete a professional-looking railing installation.
