Head exhaust fan grill

Does anyone know where I can buy a replacement head exhaust fan grill?

there is a thread somewhere on the forum about chrome plated plastic replacements, i got them about 8 years ago and they still look great.

Sam’s, just bought three this summer.

Is this what you’re looking for? If so, they make them in plastic with chrome finish or stainless steel.

Only photo I have of it installed.
