Acrylic Dome/Plastic Hemisphere - Clear - 1.5" Diameter, 1/4" Flange with Pre-Drilled Holes

Bought this to cover a “window” on a wall mounted cat box/platform. We installed steps and boxes/hammocks on the wall of our living room for our cats, and one of the tallest boxes at the end has sight windows cut into it. Within minutes, our kittens realized they could jump from this window onto a hanging lamp shade which was not sturdy enough to hold the weight of the kittens.This dome window works perfectly, true to size for what we needed and it allows our cats to still poke their heads through the sight window and look around, but keeps them from skydiving out of it.The lip flange has predrilled holes that were wide enough to fit typical screws without cracking the plastic, and the flange is about half an inch thick, which was wide enough for us to get a good attachment for our use.I also like the quality of the plastic, it’s very clear and doesn’t have any haziness fogging up the view through it.Easy to install, great price, and looks like it was supposed to be a part of the cat box the entire time.

Nice durable fabrication, mounting hole distribution is perfectly even.

I cut a hole in a 5/8 plywood just enough for this bowl to fit in. I used a cardboard sheet to create my template. I reduced the diameter during first cut and reduced it slowly until the bowl fit tight.What this did was, I didnt have to screw the bowl down as that seemed to the point of failure for others. And I didnt want any sharp stuff jutting out on the surface.Used a couple of heavy duty L brackets from hardware store and mounted below the window.Between the cat tree and this bowl, our teen kitten spends most of his time in this bowl - watching outside the window or even sleeping.Until now, the bowl hasnt come loose, despite our kitty doing all sort of acrobatic stuff on/in it. If it does, Im planning to use some sort of acrylic safe adhesive to bond the lipping to the plywood.Best purchase ever!

Worked well to protect a photo eye for dusk to dawn lights.

It rains a lot where I live. I needed to cover an indoor motion sensor that was mounted outdoors. The sensor would not work with the dome in place. Not the dome’s fault. It is nicely clear to visible light. It just won’t work in my specialized application.

I freaking LOVE this little dome window. I bought it for my chicken coop so we could see in and the girls could see out a bit. Built a little perch right in front of it and the ladies all take turns sitting and looking out, it's the best investment I have made since getting the chickens themselves.I did crack one of the screw holes by drilling in too far, so do be careful of that!

Why did you pick this product vs others?:Right size for the hole in my cat tower. Now longer wanted the passthrough and this fit the bill.

I have a videolarm FDW75C outdoor dome housing which they dont sell anymore but the dome was dull and could not see out of it. I searched everywhere for the right size and landed on this one. With a little modification if fit into my housing and now my cam images are super clear. Very happy with my purchase in fact i bought another one today.
