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.

Don’t Wait to Replace Your Traps!

  • A faulty steam trap can . . .
  • waste valuable heating dollars
  • create hot and cold spots within a heating zone
  • produce destructive water hammer
  • lead to undue wear on, and premature failure of, other traps

Factory Tested and Calibrated . . .

All parts are calibrated together under actual steam conditions and locked in precisely the correct relationship for a perfect balance. To the user, calibration means absolute uniformity of operation, greater sensitivity than perhaps was true with the original parts and simplified maintenance.

The Cage Unit is the only complete one-piece steam trap renewal containing all working parts of the trap, including the trap seat.
