SD60® Fixed Fabric Draft Curtain®
A permanently fixed fabric draft curtain for smoke zoning in aircraft hangars, warehouses, and attics.

— APPLICATION
Aircraft hangars (NFPA 409), warehouses, and attic spaces — anywhere a static curtain satisfies the smoke zoning design without a motor or control panel. Fabric fastens directly to the beam flange, beam clamps, roof decking, or a high-tensile cable at end walls; pipe penetrations get a keyhole cut and re-sewn shut with stainless steel fabric. Reduces sprinkler system requirements while meeting the strictest NFPA draft curtain thresholds in place.
