Amarine MadeBoat Yacht Rectangle Opening Portlight Porthole 15-3/4" x 7-7/8" Replacement Window Port Hole - ABS Tempered Glass, Color: White, Black (Black)

These are super easy to install and work so well quality of them are second to none. Only thing I wish is they came in bigger sizes...We used them in 2 different enclosed trailers/ camper builds and love everything about them .

Excellent Product. Five Star Service from Northern Shipments.

Installed on my sailboat quarter birth. Holds up nice.

Good quality. I ended up not using them as my plans changed, but they are very well made. For the price, you can't really go wrong. Just wish the window XXXXXXXXXXXXXXXXXXXXXX... EDIT: I am wrong. The depiction led me to believe it is to be installed as it shows in the picture. But it is not, as pointed out to me. It is to be intalled with the face you see in the picture facing the INTERIOR of the boat. Change my review to 5 star..

I received both items by fast shipping, well packed. But the gasket (attachment trim) does not work. It fits the hatch perfectly, but none of the attachment bolt holes line up (see photos).I would not install it in direct sun, or where it might be hit, since it is a bit flimsy and probably not very UV resistant.Can be installed to open inside or out: a nice feature. If installed to open in, do not install in on a sloped surface: or the guide will fill with water. It might be a good idea to cut off any excess plastic so it doesn’t get damaged or hit.
