1. Parabolic Louver: Semi-specular anodized aluminum louver has low
iridescence finish. The deep four-cell louver provides 52° cutoff. Overlap
flange provides ceiling trim while eliminating need for separate mounting
frames for different ceiling types.
2.Housing: Die-formed steel painted in high reflectance white finish.
Contoured for maximum light output. Unique overhang design permits use of
13" long 24/27 watt lamps.
3. Ballast Assembly: Ease of field inspection for servicing. Cover plate is
removable without tools.
4. Mounting Brackets: 16 ga. steel. Adjust from inside of fixture. Use 3/4” or
1 1/2” lathing channel, 1/2” EMT, or optional mounting bars.
5. Retaining Springs: Precision-tooled rust proof steel springs secure reflector
to housing for quick tool-less installation. Positive tension springs hold
reflector tight to ceiling for clean finished appearance.
6. Lamp Holder: Snap-in design allows for easy relamping, center lamp
properly over louver for even illumination.
7. Access Plate: Permits wiring without opening fixture, includes two 7/8"
knockouts. Accepts most modular wiring receptacles.
