SDA50 Aluminum Spiral Duct Grille Single Deflection

Product Application

Our model SDA50 helps you reduce installation cost by directly mounting on to spiral ducts without the need for transitions. This single deflection supply grille is available with either radius endcaps (R) or universal endcaps (U). Curved “R” endcaps allow flush mount to the duct while straight “U” endcaps allow direct mounting to the duct regardless of duct diameter. The model has a low-profile appearance, helping it blend in with the environment without being obtrusive.
