To meet OSHA fall requirements GSI has developed a low cost alternative to safety cages.  Shown below is over 1,000 lbs of dead weight applied to the skylight system.  This exceeds OSHA guidelines set at 250lbs.

Polycarbonate sheet is as clear as glass and 250 times stronger.  It's also 30 times stronger than acrylic sheet - offering a margin of safety that no other clear glazing material can beat!
