MATERIAL: 18-gauge front cover. 16 and 14-gauge
optional. Optional back panel: 20-gauge.
FINISH: Galvanized is standard. Baked enamel fin-
ishes in a variety of colors available on special order,
all models.
WALL BRACKETS/HANGERS: Order separately,
specify BKT (bracket only) or BKT ASSY (bracket
complete with SC hangers) followed by cover stock
number and quantity. Recommended bracket spac-
ing is as follows:
ELEMENTS: Copper with aluminum fins: C-340,
C-440, C-540. Steel with electro-galvanized steel
fins: S-532, S-540, S-832. Lengths from 2 to 12 feet.
See p. 30.
JOINTS: Slip joint connectors (JR models only) and
internal splice plates (JA models only; see p.5) align
cover sections which butt to one another, providing
a near seamless joint. Use of telescopic acces-
sories with any J Series model eliminates the need
to perfectly butt one length of cover to the next.
Critical linear and vertical tolerances are eliminated
because telescopic assembly absorbs misalignment
that might result from uneven floors and walls.
JL-10, JA-14 and JA-21 models mount flush with
the wall. For readily available prepackaged two-
piece fin-tube radiation refer to Multi/Pak 90,
pages 4-11.
JR-10, JR-14 and JR-21 models utilize a 4" Top
mounting rail (BPT). Allows for 3/4" recess into wall
and protects wall covering in case removing of
enclosure is necessary. Electro-galvanized finish is
standard. Optional baked enamel finish available.
Built for easy installation, long life
J Series fin-tube enclosures are functional, durable
units, popular for deluxe commercial installations:
schools, offices, hospitals, churches and office build-
ings. J Series enclosures feature a graceful, sloping
louvered top which minimizes apparent bulk, and
discourages use of the enclosure as a shelf or win-
dow seat.
• Pencil-proof louvers minimize “see through”.
• Heavy duty 14-gauge wall bracket is drawn die formed.
Secures cover in place with rigid spring lock action.
Snap-in center brace supports middle of cover.
• Bracket mounting slots provide
3
⁄4" height adjustment.
Large recessed “flat” prevents bracket from crushing wall
surface when back panel is not used.
• Element hanger has sliding guide rod that provides full
cradle width support. 1
5
⁄16" lateral movement permits
smooth, noiseless expansion. Cradle supports finned or
bare tubing at same height. Fastening slot in bracket
allows 1
1
⁄8" pitch adjustment.
• Knob-operated damper (optional) modulates fully to
control output. See page 5 for details.
