Profile: Simplex Strip Doors, Inc. manufactures clean room components, isolation curtains and hardware. Our strip doors & mounting systems like bonded bead & flex-track and accessories like gatorjaw, are designed for quick installation. Our gatorjaw eliminates troublesome nut inserts, which are required for fastening. In cleanroom settings, our AirBlock strip doors protect environments from contamination. In industrial applications, ArmorBond industrial strip doors maintain stable temperatures, and so there is less food spoilage, less shrinkage, and less frost build-up on coils. Our strip doors reduce wear & tear on compressors, motors and switches.
