Made from UV-resistant, high-quality clear plastic approximately 7/64 inch thick, it offers durable, fog-free visibility. Perfect for protective covers, pet windows, skylights, or creative projects, its half-sphere design can be paired to form a full sphere. Lightweight and sturdy, it combines functionality with sleek aesthetics. ## Description High quality 12 inch diameter acrylic dome, 6 inch high, with 3/4 inch flange. Great for many uses. Could be used as a pet window in a gate, a kid window in a playground, a cover to protect a surveillance camera (may possibly interfere with motion detection), a cover to protect an all-sky camera, a cover for a skylight (if sealed sufficiently), and anything else you can think of. Note that the shape is half a sphere and that two put together could make a nearly perfect whole sphere. Review: Perfect viewing window for catwalk box - 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. Review: Great item, good price - Nice durable fabrication, mounting hole distribution is perfectly even. ## Features - Useful for many applications - 12 inch diameter (not counting flange), 6 inch height, and 3/4 inch flange with pre-drilled holes - Clear, high quality plastic - UV resistant and approximately 7/64 of an inch thick - 4th photo demonstrates 2 domes making sphere, but only 1 dome per purchase ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01GK6ANDQ | | ASIN | B01GK6ANDQ | | Brand Name | SUPREMETECH | | Color | Clear | | Customer Reviews | 4.4 4.4 out of 5 stars (649) | | Date First Available | June 3, 2016 | | Date First Available | June 3, 2016 | | Is Discontinued By Manufacturer | No | | Item Dimensions LxWxH | 13.5 x 13.5 x 6 inches | | Item Package Dimensions L x W x H | 13.23 x 13.23 x 6.5 inches | | Item Weight | 11.7 ounces | | Item model number | 100-1.5 | | Item model number | 100-1.5 | | Manufacturer | SupremeTech | | Manufacturer | SupremeTech | | Product Dimensions | 13.5 x 13.5 x 6 inches; 11.68 ounces | | Size | 12" with Holes | | Target Audience Keyword | everybody | ## Images ![Acrylic Dome/Plastic Hemisphere - Clear - 12" Diameter, 3/4" Flange with Pre-Drilled Holes - Image 1](https://m.media-amazon.com/images/I/71r+Dmz5AdL.jpg) ![Acrylic Dome/Plastic Hemisphere - Clear - 12" Diameter, 3/4" Flange with Pre-Drilled Holes - Image 2](https://m.media-amazon.com/images/I/71vZ-0zzCML.jpg) ![Acrylic Dome/Plastic Hemisphere - Clear - 12" Diameter, 3/4" Flange with Pre-Drilled Holes - Image 3](https://m.media-amazon.com/images/I/71LoVNNdgrL.jpg) ![Acrylic Dome/Plastic Hemisphere - Clear - 12" Diameter, 3/4" Flange with Pre-Drilled Holes - Image 4](https://m.media-amazon.com/images/I/61AyMP9GUSL.jpg) ![Acrylic Dome/Plastic Hemisphere - Clear - 12" Diameter, 3/4" Flange with Pre-Drilled Holes - Image 5](https://m.media-amazon.com/images/I/61ztccwXA+L.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect viewing window for catwalk box *by C***S on July 29, 2025* Bought this to cover a “window” on a wall mounted cat box/platform.

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.
