along all edges. The inner panel shall be 3/8” thick. Both shall be electronically glued hardwood plywood
and shall be fastened together with bayonet hanging brackets at the top and two #8 x 3/4” trim head screws
at the bottom, resulting in a rigid connection with no visible fasteners on the outer wood panel. The veneer

back assembly shall be supported by two 13 gauge formed steel brackets and two 3/8-16 hex head bolts
which will attach the back assembly to the frame.
D. Armrests: Shall be kiln-dried solid hardwood, nominally 1” thick x 2-1/2” wide x 12” long, stained to match
the outer seat and back panels. The armrest will be fastened to the steel frame arm support with one 10-
24 x 7/8” flat head machine screw and one 10-24 x 2-1/4” flat head machine screw into threaded inserts on
the underside of the armrest. Chairs equipped with tablet arms shall have armrests nominally 1” thick x 2-
1/2” wide x 18” long and shall be attached to the steel frame arm support with four #8 x 3/4” sheet metal
screws.
E. Hinge: The seat hinge shall be a weldment consisting of a 7 gauge hot-rolled pickled-in-oil steel component
and shall be formed and punched to receive a 0.56” id x 0.75” od x 0.5” long steel bushing. A self-
lubricating nylon sleeve shall be fitted between the seat hinge and the standard seat hinge pin. The hinge
shall be machined to provide a positive stop location for the seat in both occupied and unoccupied
positions. The hinge shall be fitted with a plastic cover to eliminate all pinch points and shall include a
3/16” thick urethane rubber pad to dampen noise upon the seat return to the vertical position.
