ProGlass has sold over 200,000 fiberglass trench covers in the last 30 years. Our utility customers across the U.S. and Canada have achieved great gains in both safety and value by replacing heavy, crumbling, rotting and possibly failing trench covers with ProGlass products.
The National Safety Council estimates the cost of a single disabling workplace injury to be over $61,000 in the United States. ProGlass fiberglass utility products are built for safety and ergonomics - with a high strength-to-weight ratio, non-conductive materials, and ease of installation - and are built to last!
