## Compatibility and Applications

The Matrix Fitness MX185 idler set is listed for the \*\*Matrix Fitness T-5X-7X-3-F treadmill\*\*. The product page does not provide a broader model list, so compatibility should not be assumed for other Matrix Fitness treadmill models or for equipment from different brands.
