Product Details and Benefits

This product is identified as the LifeSpan TR4000i Treadmill Safety Key Lanyard, with the SKU and barcode SK48. It belongs to the Safety Keys category and is intended for use as a replacement part for compatible LifeSpan fitness equipment.

A treadmill safety key lanyard is designed to connect the safety key to the user during treadmill operation. Replacing a missing or worn component helps keep the treadmill’s safety-key system complete and ready for use. This can make the equipment more practical to use and helps avoid leaving the treadmill without an important safety component.

The part has been carefully inspected by skilled technicians for performance and safety before sale. It comes from used fitness-part stock, which gives buyers an option for replacing a needed component without purchasing an entire treadmill. Reusing fitness parts also helps extend the service life of existing equipment and reduces unnecessary waste.

Product photos are provided for reference. Because the seller carries multiple units, the part you receive may have slight visual differences from the image shown. These differences do not change the listed model or part identity.

Compatibility and Applications

The LifeSpan TR4000i Treadmill Safety Key Lanyard (SK48) is listed for the LifeSpan TR4000i treadmill. It is a treadmill safety key lanyard intended to replace the corresponding original component on that model.

This part may suit several common replacement situations, including:

- A lost LifeSpan TR4000i safety key lanyard
