Made from UV-resistant, high-quality clear plastic approximately 7/64" thick, it offers durable, fog-free visibility. Ideal for pet windows, protective covers, skylights, and creative projects, it can be combined with a second dome to form a full sphere. Trusted by hundreds of users for its clarity, strength, and effortless installation. ## Description High quality 11" acrylic dome, with 3/4" 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: Favorite lounge bowl for our cat - 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 great for stopping birds while still letting light through *by O***Y on June 2, 2026* I bought this acrylic dome to keep birds from building a nest on top of my outdoor lights, and it works well for that. The clear material is a big plus because the light can still shine through the top instead of being blocked. It solved the bird problem without making the light look too awkward. One thing to pay attention to is the sizing. The listed size appears to refer to the dome itself, not the full piece with the flange. That was my oversight, and it caused the edge to overhang more than I expected. Even with that, it still works perfectly for what I needed. - Works well for keeping birds from nesting on my outdoor light. - Clear material lets the top light still shine through. - Pre-drilled holes are helpful. - Listed size seems to be for the dome, not the full outside width. - The flange caused some overhang in my setup. - Still perfect for my use. Verdict: A useful acrylic dome that worked well for blocking a bird nesting spot while still letting the light shine through. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/54121552-acrylic-dome-plastic-hemisphere-clear-11-diameter-3-4-flange](https://www.desertcart.com.ar/products/54121552-acrylic-dome-plastic-hemisphere-clear-11-diameter-3-4-flange) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-07-07*
