, mfgr: Mainship as I recall
. Angled so no water
collects. Beautiful polished Stainless steel
. Very reasonably priced and they look much better than the original plastic ones I had (made by PI-Hi or something like that) I got 8, two different sizes were available that matched what I needed, so they slipped right in. mmimarine.com You can specify cabin

you some pics if you want.
