Gym owners and home workout folks, these WRINGKIT foam roller pads are exactly what you need when your equipment starts looking worn out! You get 8 pads in the pack, which is enough to refresh multiple machines or have spares on hand. Each pad measures about 6.2 inches long with a 3.5-inch outer diameter and 0.9-inch inner hole, designed to fit tubes from 0.85 to 1 inch thick - so they work with most leg extension machines, weight benches, inversion tables, and other gym equipment. The foam is nice and dense, giving you that firm but comfortable support during workouts. Installation is super simple - just add a little water or soapy water to lubricate your machine's tube, then slide the new pad right on. They're perfect for replacing those sweaty, torn, or compressed pads that make your equipment look (and feel) tired. Whether you're fixing up your home gym, maintaining commercial equipment, or just want fresher feeling pads for your workouts, these are affordable and do the job well. Just make sure to measure your existing tubes first to ensure proper fit, but they work with most standard exercise machines out there.
