Which type of single point nozzle is used on the type 4 hose end pantograph?

The 2-1/2 inch D-2 straight nozzle is specifically designed to work effectively with the type 4 hose end pantograph system. This nozzle configuration allows for a more streamlined flow of water, which is crucial for efficient operation in various fire suppression scenarios. The straight design of the D-2 nozzle enhances the ability to maintain a consistent discharge pattern, reducing turbulence and promoting a steady stream, which is particularly important in firefighting operations.

Using a nozzle matched to the type of pantograph ensures optimal performance; the D-2 straight nozzle facilitates better control and reach during application. In contrast, the other nozzles may not provide the same level of efficiency or effectiveness with this setup, potentially leading to less desirable outcomes in fire situations. Therefore, the selection of the D-2 straight nozzle for the type 4 hose end pantograph is based on its compatibility and performance benefits within that specific system.
