Belt vs Chain Driven Garage Door Opener

Noise Evaluation of two Chamberlain garage door openers. 1 is belt driven. The other is chain. Significant noise difference. Models: B550 & CG40D

Thank you for doing this side by side. Nobody else compares the 2 and my wife and I were trying to decide if it was worth it. We decided on the belt drive thanks to this video!

Great video. I now clearly understand the difference between belt and chain. Huge noise factor difference. My neighbor will be thankful.

My chain drive opener is just as quiet as a belt drive unit. They made a chain speader that is located right by the sprocket to keep it quieter than the old design. And as long as you do your annual lubrication to keep things running smooth, it should last 25 - 30 years. My third stall opener is 30 years old now.

you're a gentleman and a scholar for dedicating your garage to science

Odd because I have always had the belt and it makes just as much noise as the chain. I prefer knowing when someone is opening up the garage and is home so I prefer the sound. But thanks for posting… great video !

Thank you. This is just what I needed as hubby’s office is right above the garage.

Wow! I’m actually in the process of replacing my old chain unit and is why I ended up here. Just ordered one yesterday.

Wow .. having a garage built and made the right choice with the belt vs chain .. thanks for the side by side

Great video, thanks for doing this. I have a chain driven opener and it drives me nuts. That will soon be replaced.

if you want to make it quieter, go to home depot and get a tube of lucas oil products white lithium grease. Run a bead on the drive rail, and the inner trolley. It's the part that moves along the rail when the door is not attached. Hope this helps

Sold on the belt. Thanks for doing this comparison.

I was trying to find out chain or belt and based on sound, it looks like the one I have is a chain! Thanks for the video!

[jsasu.]

thanks for video....trying to explain this to my wife and now she understands

[gunnarbondank]

I do like the right one it is so quiet but the left I recommend it to

[tomatexelon]

I had all three, 1-Chain, 2-Screw, 3-Belt / Noiser to Quieter

Its funny because the actual motor sounds quieter on the belt than the chain.. It's almost like its not the actual chain that makes the noise but the actual motor in the belt driven one.. It tricks you

Belts way better great vid and well said btw our future home in Florida may have it
