SDG - Spiral Duct Grilles

Spiral Duct Grilles (SDG) are designed to be mounted on round or spiral ducts without the use of transitions. Available with single or double deflection supply and perforated return options, the SDG is highly versatile.

Typical Applications

The SDG can be used for supply or return applications and is ideal for highly visible, exposed round or spiral duct mounting. With a variety of material finishes available, the SDG can be supplied to match the duct finish, combining architectural appeal with excellent performance characteristics.
