144C56 Idler Pulley Liftmaster, Chamberlain, Sears, Craftsman for Square Rail

Glad this is as good as it looks in the pics. Slid right in and I added weight to my door to see ifnit would hold up 75 lbs extra weight. Operated it in every aspect that can go wrong with the door. Stop and reverse quickly, got caught on something making it bind and it just kept on doing it's job. Great product!!

I hope it last as long as it predecessor. My door opener is ten years old and for a small plastic part that may be the weakest part of the entire system to last that long is amazing. If this replacement lasts that long I may retire the whole thing. I am the only person I know who regularly lubricates the door moving parts. When I tell others about my door care I often hear, "what do you use for lube?" Too many mention a water displacement spray chemical. I use only garage door lube. Too bad the maker doesn't make the part from metal, but they must have a good reason. The door works well with its new pulley.

Inexpensive part. Not the same quality as oem part it replaces. I went through a couple of these until I got the tension in my chain right. It seems fine for now.Arrived in a couple days.

Fits perfectly.

Great replacement. Seems sturdy for plastic. Worked the first time. Garage door is smooth now. Recommend.

Very cheaply made plastic that doesnt stand up to stress very well. Unfortunately for this part, there’s not much options.

I wish the part came made of metal, plastic is not so durable. This is second time I replaced this part but I purchased two this time so I have a spare!

we just got it today , its a part for my washing machine.
