What is the difference between 2 way and 4-way breeching inlet?

Normally there are two types of inlet breeching available, one is 2-way another is 4-way. The 2-way version has 2 x 2½" Instantaneous male non-return valve inlets and a 4″ outlet while the 4-way inlet breeching has 4 x 2½" Instantaneous male non-return valve inlets and a 6 outlet along with 1″ drain valve

The main difference between the two is the number of hoses that can be connected to the inlet at once. While both are effective at providing water to fight fires, the 4-way inlet is usually preferred for larger buildings, as it allows firefighters to attack the fire from multiple angles at once.
