        A.    UG-1 inverted T-grid system as manufactured by F.H. Chase, Inc., 120
              Forbes Boulevard, Mansfield, MA 02048-1150. All tee members and
              components shall be extruded aluminum 6063-T5. All components shall be
              fabricated and/or machined to specified lengths and tolerances prior to
              anodizing.

              1.      System design allows for grid suspension points @ 4'-0" o.c. along
                      main tee. Each suspension point along main tee shall be with a 3/8"
                      dia. x 1/2" stainless steel cross dowel nut inserted thru the tee
                      section. The cross dowel nut accepts a 1/4" dia. threaded stainless
                      steel rod. Load bearing shall not be dependent on extruded
                      aluminum screw slot. The ultimate load capacity of each suspension
                      point shall be 3,600 lbs.

              2.      Cope each end of cross tee component for direct bearing of cross tee
                      members on main tee.

              3.      Components:

                              shown. Top portion shall provide a continuous screw slot for
                              assembly and component attachments. Lower portion shall
                              provide continuous slots for utility component attachments.
                              Hanger points shall incorporate cross dowel inserts with
                              factory assembled lower hanging components and splice
                              assemblies. Overall length shall be 12'-0" with tolerances +
                              .000", - .010" (or length as shown on drawings).

                      b.      Cross tee: Same profile as main tee with ends coped to
                              provide full bearing on main tees. Nominal lengths: 8'-0", 4'-
                              0", 3'-0”, 2'-0" (or as shown) on drawings. Length tolerances
                              shall be + .000", - .010".

                      c.      Perimeter components: Half tee or three quarter tee profile
                              with telescoping wall molding insert and retaining clip as

                                       capable of eliminating any lateral or torsional
                                       movements of the assembled joint. Where cross tees
                                       are not continuous, provide a half crossover.

                                       fabricated to interface with the grid components and
                                       filter frame to prevent lateral movement and to seat
                                       when filter gasket is compressed to 50%. Clips shall
                                       be spring loaded to allow for tee deflection.

                              2.       Blank panel clips (minimum 4 per blank panel) shall
