Use ANSI Tiers to help match enclosures to applications
You know what the job requires when it
comes to choosing underground enclosures.
The Tiers of the ANSI Standard for
Underground Enclosure Integrity (ANSI/
SCTE 77 2007) makes specifying easy by
helping remove guesswork. Tiers help
match appropriate load-rated enclosures
to anticipated vehicle loads.
Use the ANSI Tiers to know what
enclosures you need based upon various
load exposures. From light duty Tier 5
sidewalk enclosure applications to heavy
duty Tiers 15 and the new Tier 22 for
non-deliberate vehicular traffic, the Tiers
work for you to protect the public and
your system.

Our “PG” enclosures are Tier 15 rated
and give the flexibility to change to
higher Tier rated covers if the expected
load exposures increase after installation.
You can replace the lower rated
Tier 8 or 15 cover with a Tier 15 or 22
without having to dig and remove the
entire enclosure.
