Some of the products sold by 1800ceiling.com are included in the California Proposition 65 warning. What is Proposition 65?
Proposition 65 requires businesses to provide warnings to Californians about significant exposures to chemicals that cause cancer, birth defects or other reproductive harm. These chemicals can be in the products that Californians purchase, in their homes or workplaces, or that are released into the environment. By requiring that this information be provided, Proposition 65 enables Californians to make informed decisions about their exposures to these chemicals.
Proposition 65 also prohibits California businesses from knowingly discharging significant amounts of listed chemicals into sources of drinking water.
Proposition 65 requires California to publish a list of chemicals known to cause cancer, birth defects or other reproductive harm. This list, which must be updated at least once a year, has grown to include approximately 900 chemicals since it was first published in 1987.
Proposition 65 became law in November 1986, when California voters approved it by a 63-37 percent margin. The official name of Proposition 65 is the Safe Drinking Water and Toxic Enforcement Act of 1986.
The California Office of Environmental Health Hazard Assessment is establishing this website to provide the public with information on chemicals, products and locations often associated with Proposition 65 warnings. These warnings inform Californians about their exposures to chemicals that cause cancer, birth defects or other reproductive harm. Visiting this website regularly will help you learn about these chemicals and how you can reduce your exposure to them. We will be adding new information frequently.

Perfect item, fair price, quick ship. Would buy from again
I looked a long time to find a solution for a small gap on a bathroom exhaust. This was awesome! Much cleaner looking than trying to repair the ceiling. So worth it!
Very pleased with this purchase! The acrylic disc my light fixture came with looked ok when the light was on, but had a weird, blue-white color when the light was off. It was also too shiny and looked cheap.
The replacement is fantastic, fits perfectly and gives the fixture an elevated look when the light is off.
It arrived quickly too, in about a week. Highly recommend!
I ordered a custom sized disc for the overhead light in my foyer. I am not ready to replace the fixture, so I covered it with a large drum lamp shade. It looked nice except for directly underneath you could see the old fixture and be somewhat blinded by the light bulbs. The disc is sturdy but still somewhat bendable, looks professional, and functions perfectly for my purposes! I considered other DIY options, but this was worth the cost for how good it looks. You can barely tell in person that there are 3 light bulbs, it's very evenly illuminated.
Replaced bathroom exhaust fan, but new unit cover was slightly smaller than original and could see hole. Instead of uninstalling and returning, decided to just cover mistake with goof square and worked perfectly! Looks great.
I emailed customer support and they were very helpful and responded within a few hours. I went with a slightly smaller inner diameter than the base so there is no doubt the damage will be completely covered. I also had the ring cut in half so that I wouldn't have to dismantle the fan again. The fit was perfect and you can't even see where the ring was cut (see photos). The ring came with a glossy side and a textured side. Since my ceiling is a white semigloss,, I went with the glossy side. I am very happy with this solution. The company is fantastic, and the ring came in less than a week. I would use them again and I will recommend them to all my family and friends.
Ordered two acrylic tabletops for my leather nightstands, they look and fit amazingly. and also the convenience of acrylic instead of glass when you have litlle children around. No one would ever think is acrylic, it looks perfect. I just wished I had specified for the corners to be at least a minimal rounded, because they are a bit sharp, other than that, I love them. They delivered promptly. It was a smooth transition from start to finish. Highly recommended!
Used them to fill a gap between the light fixture and the ceiling (concrete so I didn’t have the drill or skill to get the hole deep enough to be flush). I ended up ordering the band about an inch wide and it looks good but I could have made them another inch in diameter and they would have looked even better.
Don’t know what covers to get? No problem with these covers! Great product, creates a sleek finished look to any light fixture with T8-size bulbs to attach to.
Ordered (2) Item 4822 white acrylic goof rings to cover unsightly areas and openings through the ceiling which were exposed when fire sprinklers heads in my unit were upgraded.
After searching for stock items everywhere online, I opted for the custom rings and am very pleased with the results. It saved me tons of extra work, i.e. spackling, texturing and repainting my ceilings.
Very quick turnaround and good communication! Thank you!
I was very impressed with the quality of the goof plate. I recently had a bathroom exhaust fan replaced and the electrician cut the hole in the ceiling too large. The new fan covering did not completely cover the hole. It was a happy discovery when I learned about goof plates and 1-800 ceiling.
The plate fit perfectly covering the hole in the ceiling. Nobody will ever know there is a small gap in the ceiling under the exhaust fan.
Went from rectangle to circular bathroom exhaust ceiling fan. Eliminated the need for drywall repair
I very rarely write reviews. When I do, you can bet I was spectacularly pleased with the product and the service as is the case with 1800ceiling! A wind storm and a falling umbrella took out the glass top of our patio table. After searching in vain for a company who sold this odd size table top (33 1/2" diameter), I was ready to junk the entire table and chair set. One last internet search for "replacement glass patio table top" brought me to 1800ceiling. To my delighted surprise, I could customer order the diameter to the exact size, the thickness and even the size of the center hole. I had the choice of clear or frosted glass. ordering and payment was a snap. I completed the order on March 29th. To my complete shock, it was delivered via FedEx on April 3rd, just 5 days later. The protective packaging was like something you would ship the Mona Lisa in. And the fit was perfect. I gave you the top rating possible but you need a few more stars to adequately describe my level of satisfaction.
Replaced a wall mounted makeup mirror with a smaller diameter mount on a wallpapered wall. Looked terrible but the mirrored goof ring was the perfect solution. Looks great next to the chrome wall mount!
Arrived super quick. As advertised. They're great quality and they look perfect with my new low profile LED recessed lights. Thank you!
