This caster is designed to fit Metro, Quantum Storage and Uline brand shelving units only. IMPORTANT: Please measure the inner diameter of your tubing to assure it’s 7/8′ ID. INSTALLATION INSTRUCTIONS: Turn your rack upside down, remove existing legs or plastic caps and tap the casters in by hitting the wheel with a rubber or plastic mallet. These are designed to fit tightly so some force may need to be used if the inside of the tubing is dirty or rusty.
