350 SERIES RATINGS
SPECIFICATIONS
Cover Assembly
Furnish and install 350 Series model_______
baseboard cover assembly as manufactured by
Slant/Fin Corp., consisting of one-piece, back and
top panel, and one-piece front panel, formed of
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 lock-
ing. 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 brack-
ets or cover, confining element to free lateral
expansion for noiseless operation. All cover compo-
nents 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.
