Patented two-piece design uses an expanding cage to grip cores, a carbon fiber based activating shaft, and U.H.M.W. polymer ribs.

• Grips cores to keep plug centered and to accommodate for variations in core ID.
• Activating shaft can be used with various cage sizes to save money when running multiple core sizes.
• Lightweight, strong, and durable.

Patented one-piece design uses a heat-treated steel body, carbon fiber carrier beam, and U.H.M.W. polymer journal

• Easy handling, single-step insertion.
• Lighter than most existing plugs.
• Durable, high-strength solution.
• Least expensive Double E core plug.

One-piece ultra-lightweight design uses a cast nylon outer body, a lightweight carbon fiber carrier beam, and an U.H.M.W. polymer journal.

• Extremely light in weight for easy lifting and handling.
  
• Single-step insertion.
  
• Advanced materials offer drastic weight reduction while maintaining high strength and durability.
