Dock Frame Aluminum End Rail

Aluminum Dock Frame End Rail – 4 FT

Finish or expand your Patriot Docks frame with this essential end support.

The Patriot Docks 4-foot End Rail is a truss-style support that spans the full width of each dock frame section. Measuring 4 feet wide by 12 inches tall, this aluminum end rail provides critical structural reinforcement and is required to complete or connect frame sections.

When do you need an extra end rail?
Each 8-foot Patriot Docks frame section includes two end rails—one on each end. When connecting multiple sections, the end rail from the next section is shared. However, an additional 4 FT end rail is required to cap off the final section at the lake end of your dock.

General End Rail Guidelines:

• Straight Dock Layouts: Require one extra end rail to finish the end
• Patio or Platform Layouts: Require two or more extra end rails depending on design
• Custom Layouts with Quick Connects or Hinges: May require additional end rails for each break or transition in the layout
• Dock Packages: Already include the correct number of end rails—no need to order separately

This end rail is made from marine-grade aluminum and is compatible with all Patriot Docks Truss Frames.

Use this part when custom-building your dock layout or adding to an existing frame. If you're purchasing a complete dock package, all necessary end rails are already included.
