Fibre-Metal F300 Face-Shield Headgear — Ratchet Crown, Z87.1

The Fibre-Metal F300 is an ANSI Z87.1 face-shield headgear crown with an adjustable channel-grip suspension and slot/pin locking cams, serving as the durable base that face-shield windows mount to for standalone use or over a hard hat — secondary protection worn over primary safety glasses or goggles.

Why the Fibre-Metal F300 is the crown, not the window

A face-shield system has two parts: a durable crown you buy once and a window you replace as it wears. The F300 is the crown — an adjustable channel-grip suspension with a slot/pin mechanism and locking cams that hold a face-shield window and set the fit tool-free across most adult head sizes, standalone or mounted over a hard hat. It carries ANSI Z87.1 basic impact for general industry, and the windows snap in as consumables. As face shields go, this is the headgear-crown base pick, and the best face shields guide and the glasses vs face shields guide explain how it layers with primary eyewear. It is the base a program buys once and re-windows for years.

What the Fibre-Metal F300 listing documents

From the published specs: an ANSI Z87.1 basic-impact face-shield headgear; an adjustable channel-grip suspension fitting most adult heads; a slot/pin mechanism with locking cams for the window; and configuration for standalone or hard-hat mounting. These are the listing's face shield headgear and face shield crown suspension credentials for an industrial face shield system. Confirm the compatible windows and Z87 marking on the listing.

How the Fibre-Metal F300 compares to other face and eye protection

For a window that mounts to a Fibre-Metal crown, the Fibre-Metal 6750CL; for another Fibre-Metal window, the Fibre-Metal 4178DGN; for a complete shield with headgear included, the 3M 8270 Deluxe; for a full-face shield with headgear, the Uvex Bionic; and for the goggle you wear under it, the Uvex Astrospec. The eye protection buyer's guide covers the range.

Where it fits by job and crew orders

The F300 suits general manufacturing, maintenance, and metalworking programs that standardize on one durable crown and re-window it as the lens wears — see the manufacturing eyewear guide and the mechanics eyewear guide. Pair the crown and window with the safety glasses or goggles they supplement, and keep the eyewear underneath clear — see the anti-fog eyewear collection and the anti-fog guide. Confirm the compatible windows and Z87 marking on the listing, and keep fresh windows on hand.
