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: Seamless Aluminum Flashing
Constructed of commercial pure grade 1100 series aluminum without seams to prevent leaking. Forward sloping design easily installs on all roof types and slopes without the need for angle adapters.

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: Ceiling Trim Ring and Diffuser
Decorative aluminum trim ring is powder coated white. Diffusers are available in 3 styles with a specific arc for maximum light dispersion to eliminate “spotlight” effects and easily snaps into trim ring.

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.
