IronMind’s Olympic loading pin and carabiner provide a safe and easy way load up barbell plates, ready to attach to anything from the Rolling Thunder to the Headstrap Fit for Hercules, the De Rigueur Dipping Belt, and the Twist Yo' Wrist. First offered in 1990, genuine IronMind loading pins have been part of many a strong guy’s workout ever since and have been featured in more world, continental and national grip championships than could easily be counted. The IronMind Olympic loading pin is 15” long and 1.9” in diameter, sized for Olympic plates, and it’s paired with a carabiner that holds 6,600 lb., giving it the capacity to not even blink at anything you’re likely to load on it. Made in the USA by IronMind, Grip Central since 1988.
