Why the Fibre-Metal 6750CL is preformed for a tight crown seal

A flat window bent onto a generic carrier leaves gaps; a window shaped for the crown seals better. The 6750CL is preformed for a tight seal on the Fibre-Metal FM400DC and FM500DC dual crown — a clear injection-molded propionate window with full brow-to-chin coverage and side flanges, meeting ANSI Z87.1 basic impact for general industry. It is the window; the dual crown is sold separately. As face shields go, this is the crown-matched clear window pick, and the best face shields guide and the glasses vs face shields guide explain how it layers with primary eyewear. It seals to the crown for a better fit.

What the Fibre-Metal 6750CL listing documents

From the published specs: an ANSI Z87.1 basic-impact window; injection-molded propionate clear material; a shape preformed for the FM400DC/FM500DC dual crown; and full brow-to-chin coverage with side flanges. These are the listing's clear face shield window and propionate face shield visor credentials as a replacement face shield window. Confirm the crown model and Z87 marking on the listing.

Where it fits by job and crew orders

The 6750CL suits general manufacturing, maintenance, and metalworking programs running Fibre-Metal FM400DC/FM500DC crowns that need clear propionate replacement windows in stock — see the manufacturing eyewear guide and the oil and gas eyewear guide. Pair the window with the safety glasses or goggles it supplements, and keep the eyewear underneath clear — see the anti-fog eyewear collection and the anti-fog guide.
