SPECIFICATIONS

Housing:

6063 T5 extruded aluminum.

Optical system:

Constructed of highly specular aluminum, and highly reflective 24 ga. metal, to produce an indirect distribution.

Row ends:

1/4" aluminum end plate or mitered aluminum extrusion end caps.

Joints & Intersections:

All joints shall be accomplished using QuickLock joining system. Optional connectors in "L", "T", or "X" configura-tions, shall be mitered aluminum extrusion.

Mounting:

Brackets attach to existing structure anywhere behind fixture. Fully adjustable mounting brackets to provide up to 1/8" wall variance and allow for vertical fixture leveling.

Electrical:

All luminaire sections shall be factory pre-wired to section ends. Optional quick connect plugs are available.
