FM4178DGN - Fibre-Metal 4178DGN High Performance Propionate Face Shield Window, Dark Green

Clear Vision and Tough Protection with Fibre-Metal

When you are on the grind, you need a face shield that doesn't just protect you—it needs to let you see what you're doing. The Fibre-Metal 4178DGN Dark Green Face Shield Window is built for welders and fabricators who demand the best in optical quality and durability. Unlike cheap, flimsy replacement visors, this window is made from injection-molded propionate. This means you get a crystal-clear view of your workpiece without the wavy distortion that can cause headaches and mistakes.

The Dark Green tint is perfect for shops with bright lighting or for tasks that generate distracting glare. While it keeps the brightness down, it doesn't compromise your ability to see fine details. It fits perfectly onto your existing Fibre-Metal F-400 or F-500 headgear. Because it comes pre-formed with the correct curve, it snaps right into place and creates a solid seal against the crown protector. This is crucial for keeping grinding dust, sparks, and floating debris from falling behind the shield and into your eyes.

Safety is the top priority, and this shield delivers. It meets ANSI Z87.1+ high-impact standards, giving you confidence when the sparks start flying. The 0.060-inch thickness is tough enough to handle the rigors of daily shop life, resisting pitting and scratching better than standard acetate shields. Whether you are chipping slag, grinding down a weld, or working near bright reflection, this replacement window keeps you safe and focused.

Don't settle for generic, flat replacement sheets that you have to wrestle onto your headgear. Upgrade to the Fibre-Metal 4178DGN for a professional fit and finish. It’s an essential accessory for any welder's safety kit, ensuring that your face protection is as tough and reliable as the welds you lay down.
