XJJ 41A3489 Garage Door Openers Carriage Complete Trolley Assembly Compatible with Chain Drive Operators Made by Liftmaster, Chamberlain, Sears Craftsman

Worked great , easy to install , the bar was a T shape , fit perfectly

Not exactly match my existing but have to adapter, make the hole greater and some other changes at the end it worked, great quality though, you can not find the original, be patient and save money .

Came fast and fits right- replacing isn’t as easy as the initial install but I only needed the inner trolley. Just a pain to get it on the track- remember when attaching the chain to re center the motor stopping sensor inside the motor casing.

Purchased to replace broken traveler on a 2007 chamberlain opener. No instructions but was pretty easy having watched a YouTube on replacement. About four bolts and two cotter pins to remove in order to replace. Wear old clothes as the filthy chain will be dangling or falling on you. Also - unplug garage door opener to avoid any lost fingers should someone open the door while fixing.

It took me like 10 minutes to install looks and works just like the original.

Great solid steel construction. Can be used for a chain or belt system. Worked like a charm.

The old trolley chassis bent and was unusable. This product arrived very quickly and less than three days after the old chassis broke, I replaced it with this item and we're back in business!

I misdiagnosed a garage door opening problem and bought and then fitted (thank you YouTube) this carriage trolley assembly. It came with all the bits I needed (less grease for the track) and works fine, even though it's not manufactured by the maker of my door-opening system. My hope was that I would avoid a call-out charge and repair bill for a specialist company to come and fix the issue. I was wrong, but at under $30 and 90 minutes of my time, I don't consider it a big loss. If you're semi-competent at DIY this may be a quick-fix to your garage door difficulty.
