V-shaped clear window with a universal hole pattern

A flat window leaves a gap at each cheek, and a V-shaped one closes it. This clear polycarbonate window bends to follow the line of your face and takes particles, flying chips and splashes before they reach your glasses. It is 15 inches wide, 9 inches tall and 0.060 inch thick, and it comes uncoated.

We drill it with a universal hole pattern. It fits our 301 Series crowns and many crowns from other makers, so you can keep the headgear you already wear and replace only the scratched window. Line the holes up with the crown pins, seat the window evenly, and make sure it clears your chin before you start the grinder. It is marked to ANSI Z87+ and CSA Z94.3.

The 301 Series V-Shaped Window is on the Face shields shelf of the Sellstrom catalog.

Before you start

A face shield goes over safety glasses or goggles, never instead of them. OSHA's guide says a shield alone does not stop an impact, and a pitted or scratched window is the cue to replace it.

This is general information about choosing protective equipment, not a hazard assessment of your workplace and not medical advice. Your employer's assessment, the markings on the product and its instructions come first; after any injury to the eye, get medical help right away.

What the safety sources say

OSHA Publication 3151: Personal Protective Equipment. Describes safety spectacles, goggles, welding shields and face shields, and says face shields protect against splashes and sprays but not adequately against impact, so worn with goggles or safety spectacles they give added protection. It also says hearing protector makers must print the NRR on the packaging and that glasses, facial hair or long hair can reduce the protective value of earmuffs. Read October 2, 2026.
OSHA, 29 CFR 1910.133: Eye and face protection. Employers must ensure appropriate eye or face protection against flying particles, molten metal, liquid chemicals, chemical gases or vapors and injurious light radiation, with side protection against flying objects, and filter lenses must carry a shade number suited to the work. Devices must meet ANSI/ISEA Z87.1-2010, Z87.1-2003 or Z87.1-1989 (R-1998), and the table sets minimum shades such as 10 for gas metal arc welding at 60 to 160 A and 14 for carbon arc welding. Read October 2, 2026.

Each of these sources is linked in our eye and face protection guide.
