NO-RUST WEATHER LAST™
WALL SLEEVE AND FRONT
PANEL
The indoor front panel and non-insulated wall sleeve
use nonmetallic compounds that never rust or corrode,
do not support combustion, and do not give off toxic
fumes. The weather-resistant feature exceeds require-
ments of Underwriters' Laboratories and resists dam-
age caused by impact and scratching. The Weather
Last feature also insulates and has up to 10 times the
acoustic absorption of metal cabinets.
Standard Wall Sleeve (Plastic or Metal)
Insulated polymer wall sleeves combine all of the
above features with the option of factory-installed
insulation. The insulation helps to reduce heat loss,

of sizes for most standard and deep wall applications.

All metal wall sleeves come with factory-installed
insulation, designed to minimize heat loss and reduce
