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

Constructed from Class 25-30 gray cast iron, this industrial-grade post ball cap offers excellent durability, compressive strength, and a solid, one-piece construction that withstands environmental exposure. Its material properties make it ideal for welding onto steel posts, providing a seamless and robust connection that enhances the structural integrity and longevity of any ornamental ironwork project. The raw cast iron finish is ready for priming and painting to match any design specification for commercial applications.

This versatile 2-1/2 inch ball cap is essential for fabricators, contractors, and MRO professionals working on architectural metalwork in the Los Angeles area. It is primarily used to terminate fence posts, gate frames, and handrail systems, protecting the interior of the tubing from moisture and debris. Its classic spherical design complements a wide range of styles, from traditional wrought iron fences to modern industrial railings, making it a staple component for both new construction and repair projects. Warehouse stock is available for same-day pickup.

Target Users

This product is ideal for metal fabricators, welding shops, fencing contractors, and maintenance teams specializing in ornamental iron, construction hardware, and architectural steel projects.

Finish Options

Our 2-1/2 Inch Post Ball Caps are supplied in a raw, unfinished state, perfect for custom finishing. This surface is ideal for welding and can be prepared for various coatings, including industrial-grade primers, alkyd or epoxy paints, or durable powder coating to match any project's color scheme and provide excellent corrosion resistance.

How to Measure

To ensure a proper fit, measure the outside diameter (OD) of the post or tubing you intend to cap. This ball cap is designed to fit snugly over a 2-1/2 inch OD post. For square tubing, measure the flat outer surface from one side to the other. For round tubing, measure the diameter across the widest point.

Example: To order, specify "2-1/2 Inch Post Ball Cap, Cast Iron" for a square tube measuring 2-1/2" x 2-1/2".

Order Checklist

  • Product name and required dimensions (e.g., 2-1/2" Post Ball Cap)
  • Material specification (Cast Iron) and quantity
  • Confirm compatibility with post profile (Square or Round)
  • Surface finish requirements (e.g., Raw for painting)
  • Welding or installation supplies needed
  • Special handling or delivery requirements
