20 MTU Installation Requirements
Meter Pit
Use the short spacer if the lid is flat, and does not have MTU mounting provisions,
OR has mounting provisions that are even with the bottom of the lid.
Long Spacers
In some rare situations the use of the tall spacer is needed. The tall spacers are
used when the bottom of the pit lid is not flat and there are no provisions for
mounting the MTU. The need for the Long spacer is specified at the time of lid
qualification.
Summary
• Mount the MTU to approved, non-metallic meter pit lids only.
• Mount the MTU with the label facing the pit lid.
• Use the appropriate spacers for the type of meter pit lid.
