Barnes & Jones Steam Traps

THE “TRAP WITHIN A TRAP”

What Is A Cage Unit?

The Cage Unit is a “trap within a trap”—an integrated combination of all the working parts of the trap, including the trap seat. It can be easily installed at less than half the cost of a new trap without disturbing the piping.
