What is the device that is used to join two sections of guide rail together?

The device used to join two sections of guide rail together is known as a fishplate. Fishplates serve a crucial role in ensuring the structural integrity and alignment of the guide rails in elevating devices. These plates are typically made from steel and provide a reliable connection that helps maintain the correct spacing and stability of the rails, which is essential for the safe operation of elevators and similar equipment.

While connector plates and rail splices may also be used in various contexts within construction or other types of mechanical assemblies, they do not specifically refer to the method of joining guide rails in the same way that fishplates do. The guide bracket, on the other hand, often serves a different purpose, typically relating to the support of the rails rather than their joining. Therefore, the term fishplate is the most accurate choice in this context for joining guide rails.
