Designed for Commercial Use: Engineered to integrate seamlessly with the Nike Strength Pro rack system using 1-inch hardware. Built-In Barbell Protection: A nylon sleeve and rubber bumper prevent metal-on-metal contact, helping protect barbell sleeves and endcaps during repeated storage. Efficient, Space-Conscious Storage: A shortened storage tube allows for smooth loading and removal of barbells, even inside the rack or in low-ceiling and tight training environments. Tested for Long-Term Durability: Rated for commercial storage and tested to ASTM standards at 2.5 times its stated load.
