CHARACTERISTICS:

All the sides of the boxes have special punchings of different sizes so that with a few blows the punchings can be opened to accept the hose. These punchings are specially shaped to fit the adaptable couplings with a simple 45º twist. The hosing is then pushed into place. This does away completely with the need for threading or screwing. Each inlet to the box accepts the size of tube indicated, using normal couplings, or directly without the use of other accessories if hollow screws are used. The boxes also accept tubes of a diameter immediately below the size of that indicated, using reducers or reducing washers if using hollow screws. The base of the boxes also have punchings to enable them to be placed at will. These boxes can be supplied on request without punchings or with different sizes or positions of the same.
