Installing a skylight is easier with the Instant Light Shaft

The Instant Light Shaft is faster, cleaner, more efficient and cost-effective than traditional drywall installation. It can be installed in an hour versus 20 hours over 3 days - it's that easy!

• Works on all "box" type, 90° light shafts (no flare).

• 16" standard depth (trim to actual on site).

• All other pieces are pre-cut to size to be site assembled.

• 4" minimum spacing required around all sides if multiple skylights are installed
