Keep your toolboxes clean and organized with Irish Iron Wrecker's Tool Box Accessory Line. Our four shackle rack will hold many different shackles but capacity is dependent on shackle size. This rack is constructed from 10 gauge steel and is designed for light, medium, and heavy duty shackles. It is finished in a semi gloss black powder coating for enhanced durability. All of our Tool Box Accessories are designed to bolt back to back to minimize drilling of holes.
