used for the maximum weight of the hood to ensure
the ceiling structure can support the weight of the
hood when filled with water.
CAUTION
To ensure proper structural support, all hanger
brackets must be used for hanging the hood.

Base weight is based on 48 inches (121.92 cm) hood
length. For each additional foot of hood in length, add
55 lb/ft (24.95 kg/m) in weight of hood and 67lb/ft
(30.39 kg/m) in weight of hood filled with water.
Example of a 10 foot hood:
Dry: 48 inch width x 120 inch length
= 440 lbs. + (6 ft. x 55 lb/ft)
= 440 lbs. + 330 lbs.
= 770 lbs.
With Water: 48 inch width x 120 inch length
= 488 lbs. + (6 ft. x 67 lb/ft)
= 488 lbs. + 402 lbs.
= 890 lbs.
