Seneca Steel Erectors

Other colors may be available at an additional cost. The ridge vents can be used both with Nucor "Classic Roof ”™ and Nucor "CFR”™ roof systems. Nominal ridge vent length is 10’-0”. They have flat skirts for both "Classic Roof”™ and "CFR”™ systems and are attached to the major ribs (or End Dam on the "CFR"™) with self-drilling screws. 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.
