cold rolled steel. Bottom and top edges of back
panel shall be formed to provide channels along
entire length, to receive full-height support brackets.
Brackets shall be die-formed of electro galvanized
cold rolled steel, for rigid bracing and spring locking. Slide-action expansion cradles, formed of
polypropylene, shall be inserted between heating
element and support bracket. Cradles shall protect
element bottom and sides from contact with brackets or cover, confining element to free lateral
expansion for noiseless operation. All cover components with a 19-gauge front cover shall be painted
in Nu-White thermosetting polyester enamel and all
cover components with a 16-gauge front cover
shall have a galvanized finish.
Extra-cost Options
Optional damper shall be provided for each length
