having the complete meter set completely assembled. They are made with heavy,
one piece I-Beam construction to protect the meter from piping stresses and
ensure a solid installation. The meter bars offer compact space saving
installations for both single home and multi-unit residences. National Pipe
Threads (NPT) are provided on the inlet and outlet tappings. Swivels are
provided with flat gaskets or o-rings. Manufactured by A.Y. McDonald.
