Ridge Vent
Ridge vents come completely assembled for ease of installation. Ridge vents
supplied by Metal Building Depot are of a low profile design to provide gravity
type ventilation. Because gravity ridge vents are designed to allow free
airflow, some penetration of water during blowing rains is to be expected.
Standard available finishes for the ridge vents are polar white and galvalume.
Other colors may be available at an additional cost. Nominal ridge vent
length is 10'-0". Ridge vents are available with 9" and 12" throats. Bird
screens are provided as a standard. The ridge vents can be ordered as
continuous or single units. Exterior parts are 26 gage painted or galvalume.
Interior parts are all made of G90 galvanized steel. The substructure consists
of 10 gage saddle straps with interior baffles of 24 gage steel. Lifter arms
and damper slides are made of 18 gage steel. Manual operation is through
activation of a pull bar which is attached internally to bell cranked type
lifter arms connected to the damper with Teflon coated pins through the damper
slides. Dampers are spring loaded to remain in the open position until the pull
bar is operated and locked in the closed position. Dampers operate in a
vertical manner. Each vent is opened by a pull chain that extends approximately
12" below the roof unless noted otherwise on the order documents. Other opening
mechanisms are available at an additional cost upon special request. Ridge
vents should not be placed closer than 5'-0" to the endwall steel line to allow
room to properly flash the building. For example, a 90'-0" long building with
ridge vents required the entire length should have no more than (8) units. The
ridge vents are available with the following accessories:
-
Single unit w/ screen and damper (center pull 10'-0" - chain package)
-
Single unit w/ screen (no damper)
-
Continuous unit w/ screen and damper
