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.

Constructed of commercial pure grade 1100 series aluminum. Square shaped flashing easily installs over curb. Curb box should be constructed on-site according to local building codes 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.

Decorative aluminum trim ring is powder coated white. Diffusers are available for standard sheet rock ceilings or for suspended warehouse installations.
