I have a craftsman garage door unit. Just curious if they use a different belt because this particular belt does appear to be the (new version) as it has 20 grooves per 6”.
The 41A5250 belt specifies that it's specifically for Chamberlain openers. We don't sell this belt but it does appear to be the same as the 41A5434 (Liftmaster is a division of Chamberlain) however we have seen some retailers note some specs of the belt that are different from the 41A5434. Most list it as 233" in length but we've seen some list it at 237". We've also seen it listed for square rails only (where most of the Liftmaster openers use a T rail). Since we don't sell the 41A5250 belt I can't confirm the overall specs of the belt. If you're looking to replace the belt on your operator then I would suggest that you use the belt part number found in the opener manual specifically for your model of operator to avoid any issues that there may be between the two parts.
Ignore the rail and measure the belt. If you were to remove the belt and measure the overall length it should be around 233" long for a 7' operator belt. If you need the older style of belt then it would be the 41A3589-3 7' Belt and if you need the newer style of belt it would be the 41A5434-11A 7' Belt.
If you have a 9' high garage door then most likely you have a 10' garage door operator. If you have an 8' garage door operator connected to a 9' high door then that operator would not be able to open the garage door the full 9' and the bottom section would hang in the opening. It's possible to attach an 8' opener to a 9' high door but it's unlikely. This is why we recommend that you should measure the overall length of the belt to confirm the appropriate replacement for your operator.
If the belt is still installed on your operator then you can measure the length of one side of the belt and multiply that by 2. That should give you a rough estimate of the overall length of your belt. If the measurement you come up with is close to 233" then that would mean that you have a 7' operator and require a 7' belt.
Are you asking about the overall length of the operator or what is called a 10' operator? There's a difference. For example, a 7' garage door operator is actually going to have an overall length of about 10'. While a 10' operator is going to be around 13' in overall length. So if you have a 7' operator on a 7' high garage door the overall length of the operator itself is going to be around 10'. That's why it's always important to measure the overall length of the belt when it's laid out on the floor so you get the correct belt and not the length of the operator. If you are asking if an actual 10' operator (which would be around 13' long) would ever be used on a 7' high garage door the answer is yes. It would be rare but there are some situations where it would make sense. For instance, if there was a beam or duct that was 10' back into the garage & it just happened to be right where the powerhead of the 7' opener would get mounted then it may make sense to use a longer 10' operator rail so the powerhead could be mounted on the other side of the obstruction. Hope this answers your question.
This isnt correct information. I measured the distance between my two pulleys and it was 10 feet. But there is way too much length. It takes about an 8 foot belt. Now i have to pay for return shipping. Whatever the distance is from gear to gear. Go about a foot shorter than that.
As we explain in the video, the 7', 8' and 10' that the manufacturer puts on the packaging refers to the height of the garage door not the length of the belt. We explain that you should measure the height of your garage door and also measure the actual belt. We explain how to measure your belt here: ua-cam.com/video/mMWV7ffkHf8/v-deo.html. If you were to remove the belt from the operator you'd notice that it is one long piece (like a piece of spaghetti) and not a solid loop (like a tire). That is how they get the measurements for the overall length of the belt as a 7' belt is 233" long, an 8' is 255" long and a 10' belt is 307-1/2" long. If you measure one side of the belt while it's still on the operator and multiply it by 2 then you'll get a measurement that is close to what you are looking for. For a more accurate measurement you can remove the belt from the operator and measure the overall length.
Hey, I just wanted to say thanks for the awesome video. You saved me so much headache and money
Great to hear! Thanks for watching.
Wish i saw this before. But glad I'm watching now
Thank you for sharing your knowledge with us.

No, the Sears/Craftsman openers would use the same belt as the Liftmaster openers since the Craftsman openers are made by Liftmaster.
While looking for a 41A5434, I keep coming across a 41A5250 part, which looks identical. Is this compatible / the same thing?

Help Plz... My door is 7ft tall... From pulley to pulley on the rail is 10ft. Which size belt do I need?
Ignore the rail and measure the belt. If you were to remove the belt and measure the overall length it should be around 233" long for a 7' operator belt. If you need the older style of belt then it would be the 41A3589-3 7' Belt and if you need the newer style of belt it would be the 41A5434-11A 7' Belt.
2:35 I have a 9ft door, would it always be a 10ft belt or could it be an 8ft?
If you have a 9' high garage door then most likely you have a 10' garage door operator. If you have an 8' garage door operator connected to a 9' high door then that operator would not be able to open the garage door the full 9' and the bottom section would hang in the opening.

my garage door is 7' How to measure the belt of my garage door ..all along? or supposedly the way it is installed?
If the belt is still installed on your operator then you can measure the length of one side of the belt and multiply that by 2. That should give you a rough estimate of the overall length of your belt. If the measurement you come up with is close to 233" then that would mean that you have a 7' operator and require a 7' belt.
What about the hooks/ends. The one i bought i had to modify the hook
You shouldn't have to modify anything on the belts so I'm not sure why you would've needed to do that.
Would there ever be a 10ft operator with a 7ft door?
Are you asking about the overall length of the operator or what is called a 10' operator? There's a difference. For example, a 7' garage door operator is actually going to have an overall length of about 10'. While a 10' operator is going to be around 13' in overall length.
