          2.7ACCESSORIES
 
          A.C-Hangers: Suspension hangers that are direct-screwed to the panel and hang over the heavy duty-grid. Hangers are made of spring-steel with phosphate pre-treatment and corrosion-resistant coating.
 
          B.Torsion Springs and Saddle Clips: Two parts of a suspension system in which the torsion spring is direct-screwed to the panel and compressed to attach to the saddle clip that is fitted over the heavy duty-grid. Springs and clips are made of spring-steel with phosphate pre-treatment and corrosion-resistant coating.
 
          C.Acoustic Nonwoven Backers: Thin, sound-absorbing fabrics that can be applied to a substrate in order to increase sound attenuation.
          ** NOTE TO SPECIFIER ** Coordinate with Rulon's Integrated Lighting program in partnership with GE Lighting. The program is an effort to coordinate MEPs more effectively and provide for a more streamlined process of integration. In practice, this effort begins with factory cutouts to accommodate light fixtures. Contact the manufacturer for additional information.
 
          D.Integrated Lighting System: Coordinate ceiling panels with lighting specified in Section 26 51 13 - Interior Lighting Fixtures, Lamps, And Ballasts
 
          E.Z-Clips: Male/female aluminum attachment clips, similar to a French cleat but with a thinner profile, used to hang wood wall panels on furring strips.
 
          2.8SUSPENSION SYSTEMS
 
          A.Main Tees: Standard heavy duty 15/16 inch (24 mm) T-rail specified in Section 08 11 16 - Aluminum Doors and Frames.
 
          B.Hangers; shall be Suspend ceiling panels from T-rail using torsion springs, C-hangers, or direct screw attachment, as recommended by the manufacturer.
          1.System for Linear 4.5 inch open, 6 inch open, and 4 inch closed shall consist of Rulon cliprails, installed on #12-gauge wire hangers.
          2.Linear wood system cliprail shall use clips factory-attached to the main tees, factory indexed to maintain the specified module.
 
          C.Accent Beams: Fabricate to attach to the ceiling/floor deck above. Beams may be suspended using threaded rod or #12 hanger wire. Accent Beams are intended for decorative purposes only, electrical fixtures, HVAC equipment and fire suppression components should be independently supported and shall not rest on or wrap around the beams in any way.
 
          2.9FABRICATION
