The Mastodon Engineered Frame System

is one of the most heavy duty batting cages on the market. Using four massive structural steel poles and a cable tensioning system, you get the strength you need without lots of extra components.


  • 8.625" diameter
  • corrosion-resistant coating
  • completely prepared to accept tensioning hardware
  • custom options available

The Mastodon batting cage frame system includes 8.625" outside diameter structural steel pipes coated with the same finish used on the Alaska Pipeline. It has fewer components, and offers free and clear spans up to 75' in either direction - without significant sag. The poles come completely prepared to accept our tensioning hardware.

Corrosion Resistant Coating

All poles are corrosion dipped, finished with STRYK 5388, and sealed with a welded top cap preventing internal corrosion. STRYK 5388 forms a solid coating which bonds to the substrate, preventing corrosion even if coating is scratched or damaged. STRYK 5388 is a thick rust-inhibitive coating used on the Alaska pipeline with a high degree of impermeability to moisture. The finish remains highly flexible and elastic in extreme temperatures. It will not support fungal growth in humid or water-immersed environments or crack in extreme weather conditions.

Cable Tensioning System

  • 3/16" aircraft cable
  • ensures your net will hang properly
  • larger diameter cables available

Our cable tensioning system uses galvanized hardware including 3/16" aircraft cable, cable clamps, thimble eye nuts, eye bolts, institutional grade threaded rod, and curved washers.


Two Mastodon batting cages side by side sharing the center poles. With this system, you save money on the cost of materials, labor, and shipping. Each cage is two feet apart so that balls from one cage will not injure players in another cage. Additional configurations are available.
