Overview
NCA offers several options for galvanized and stainless steel control dampers. The SCD-57 (low leakage version = SCD-LL-57) is NCA’s “go-to” galvanized steel control damper. NCA also has the ability to build control dampers with more custom options with the OBD-106 and PBD-100 such as different gauge steel as well as 304 or 316 stainless steel. NCA also has the ability to fabricate round control dampers as well as provide factory mounted controls on any control damper made.
