1a: Acrylic Dome
Modified acrylic construction provides unsurpassed weatherability and superior impact strength. Able to withstand large temperature swings, leakproof, prevents condensation and blocks out harmful UV rays.

1b: Aluminum Curb Mount Flashing
Constructed of commercial pure grade 1100 series aluminum. Square shaped flashing easily installs over curb. Curb box should be constructed on-site using 2¨ x 10¨ lumber and carefully sealed with roofing material.

1c: Highly Reflective Light Pipe
Miro-Silver surface specially designed for 98% reflectivity of pure white light even in early morning and late afternoon. Light pipe is NOT a laminated polymer sheet – can’t delaminate, yellow, crack or peel.

1d: Transition Box
Constructed of rugged aluminum powder-coated white. Easily fits all standard drop ceiling grid systems and is available with 2 choices of diffusers styles: Prismatic or SkyBrite.

2a: Flat Roof Flashing
Constructed of commercial pure grade 1100 series aluminum without seams. Unique round shape allows for easy installation on flat roofs without disturbing much of the roofing material.
