light distribution and good
efficiency.
• Die formed perforated steel
modular housing lengths – 4’
and 8’.
• Incremental mounting on the
ceiling grid - 4’ and 8’
centers.
• Precision die cast end caps.
Construction: Two piece housing is die-formed
cold rolled steel, forming an 8-5/8” x 1-3/4”
architectural profile. Standard 4’-0” and 8’-0” fixture
lengths combine for individual or continuous runs.
End Caps: End caps are precision die-cast
aluminum, mechanically attached with no exposed
fasteners.
Reflectors: Optical reflectors are die-formed high
reflectance white painted steel.
