Fibre-Metal Quick-Lok Cups FM4001

Bought for my son but have purchased 100's of these for our welders before I retired. They stand up well.

Works perfect. The pipeliner hood is a bit tight with the quick disconnects but it does work just fine. But this all depends on which hard hat you are using.

I ordered two sets of these adapters because it seemed as though it included the male and female pieces. When it got here it was only the female pieces.

Great product, it replaced my speedy attachment. Only issue is when using the pip-liner helm by fiber metal, on the fiber metal roughneck hard hat it tends to bend the quick lock cup on the right side when bringing your helmet to the down position, then locks it self back into the cup lifting the welding helmet back up, I think this is only a issue for very stiff and hard helmets like the pipe-liner. But still works.
