  • Modular Strength – The 3-piece design bolts together using heavy-duty ½” Grade 8 hardware, delivering serious durability with serviceable flexibility.
  • Backup Visibility Ready – Dual recessed mounts allow you to add 3” cube lights for improved rear lighting in low-visibility situations.
  • Built from Real American Steel – Constructed entirely from 3/16” USA plate steel and designed and manufactured in California.
