3 Inch Post Ball Cap

Enhance and protect your fencing or railing with our 3 Inch Post Ball Cap.

Overview | Specifications | Applications | Finish Options | How to Measure | Order Checklist

This 3 Inch Post Ball Cap is manufactured from high-quality Class 25-30 gray iron, a standard in durable architectural castings. This material provides excellent compressive strength and natural corrosion resistance, which can be enhanced with proper finishing. The casting process ensures consistent dimensions for a secure fit and a classic, solid feel. Its substantial weight and robust construction make it a superior choice for heavy-duty industrial and commercial fencing projects where longevity and aesthetic appeal are paramount.

Ideal for metal fabricators, fence contractors, and MRO teams, this ball cap is a critical finishing component. It is commonly used to terminate the tops of steel or iron fence posts, gate frames, and handrail systems. Beyond its decorative purpose, the cap prevents internal moisture accumulation and rust, extending the life of the entire structure. These industrial-grade post ball caps are stocked at our Los Angeles warehouse for immediate, same-day pickup, supporting both large-scale fabrication jobs and minor repairs.

Specifications

  • Material: Class 25-30 Gray Iron
  • Standards: Industry Standard for Ornamental Castings
  • Strength/Tensile: N/A (Excellent Compressive Strength)
  • Dimensions: Designed to fit standard 3" x 3" square or 3" OD round tubing/posts.
  • Finish: Raw/Unfinished (Ready for paint or powder coating)
  • Certifications: N/A

Applications

  • Architectural & Commercial Fencing: Providing a decorative finial for office parks, residential complexes, and public spaces.
  • Security & Perimeter Gates: Capping gate posts to prevent water ingress and add a professional finish.
  • Handrail & Balcony Systems: Terminating vertical posts in railing systems for safety and aesthetics.
  • MRO & Repair: Replacing damaged or missing caps on existing metalwork and fences.

Target Users

This commercial post ball cap is used by metal fabricators, fence installation contractors, and maintenance teams for projects requiring durable and decorative metal components. It is a key piece of construction hardware for new builds and repairs.

Finish Options

Our 3 Inch Post Ball Caps are typically supplied in a raw, unfinished state, perfect for custom finishing. This allows fabricators to weld them directly to steel posts before applying a final coat. They are ready to be primed and painted with industrial coatings, such as DTM alkyd enamels, or can be powder-coated to match any project's color scheme.

How to Measure

To ensure a proper fit, measure the outer dimensions of your post. For a square post, measure the width of one side. For a round post, measure the outside diameter (OD). This ball cap is designed for a nominal 3-inch post, fitting securely over a 3" x 3" square profile or a 3" OD round profile.

Example: Order Specification: 3 Inch Post Ball Cap for 3" x 3" Square Post.

  • Grade/material specification and quantity
