## ProForm 305 CST Treadmill Safety Key Lanyard

The ProForm 305 CST PFTL40917 Treadmill Safety Key Lanyard is a preowned replacement safety key for the ProForm 305 CST treadmill.

A treadmill safety key connects the user to the machine’s safety system while the treadmill operates. The lanyard gives the user a way to attach the key to clothing or keep it positioned for use. If the original key has been lost or damaged, replacing it with the correct model-specific part can help restore the equipment’s intended safety-key function.

Product Details and Benefits

This item includes a **ProForm treadmill safety key and lanyard** listed for the **305 CST model, model number PFTL40917**. It is sold as a preowned fitness equipment part rather than a new replacement. Each part has been carefully inspected by the seller’s technicians before shipping.

Choosing a used treadmill part can provide a practical replacement option when the original component is no longer available or when you want to avoid replacing a larger treadmill assembly.
