RE: Tate GrateAire 24" with Damper - what is best orientation to rack, slots perpendicular or parrallel? Thank you for your inquiry, With the Damper, you would orient the slots perpendicular to the rack. The slots on the damper can be adjusted from 0-100% range towards the rack with quarter turn adjustment. If you would like further clarification on this, please feel free to contact your Server Racks Online sales representative directly. |
