The hardware is likely bronze, not brass. Brass isn't used much on boats, since it doesn't hold up to salt water exposure all that well. It would help if you said what kind of boat you had, since it may be a stock part on that boat, with a known source... I'd highly recommend you read this POST to help you get the most out of sailnet.

Hatch Slide Hardware
The brass rail on my main hatch coaming is in solid condition, but the brass slide on the hatch itself is wearing thin. Does anyone have a source for its replacement? Or a new set, supposing that getting the right dimension slide for the original rail might be a problem?
