So I’m trying to make replacement lenses out of polycarbonate to cater for all various different masks out there, I’m wondering if any savvy gas mask owners would be kind enough to measure and tell me the specification of said lenses, I need to know the diameter and thickness and any other information I would need to know in order to make the lenses.

Currently I only make S10 lenses, I’m happy to provide a free lenses set that I make to anyone (well the first people) who gives me manufacturing specifications for each kind of mask.

I’m currently looking at the more main stream masks, FM12 and GP-5 but im happy to make any (flat lenses) for any kind of masks.

Thank you.
