Fibre-Metal® 4199CL extended view clear high performance faceshields provide an additional 1 3/4 inches of vertical protection compared to the standard 4178 series window. They are SEI certified to comply with current ANSI
standards. SEI certification is your assurance of consistent quality and performance.
Fibre-Metal 4199CL clear faceshield windows measure 9 3/4 inches long X 19 inches wide. They are injection molded from propionate, which is superior to
other window materials in every significant performance characteristic. They are pre-formed
at the factory to the exact curve of our crown protectors for easy installation, an exact fit and
a perfect seal against dust, dirt and debris. All High Performance windows are .060" thick
for an extra margin of protection, yet they cost no more than ordinary .040" thick windows.
