Super-Compact Ceiling Hanger

Low-profile isolated ceiling construction using a resilient hanger assembly to support one or more layers of gypsum board is desired by architects wanting to minimize ceiling drop in an occupied space. The Model KSCH Super-Compact Ceiling Hanger helps the designer achieve the goal of resiliently decoupling the ceiling using less than three and one half (3-1/2) inches of space. Model KSCH is designed to allow use of a single piece of 1-1/2" x 1/2" cold-rolled channel to support the drywall furring channel to which the gypsum board is attached. Renovation and new-build design ceiling height concerns are addressed easily with Model KSCH.
