  1. Sensor Change 4 Star Review

    The sensors are working great! But it took me a bit of time to figure out how to attach them so they were clear of the rail. Since there wasn't anything in the instructions about it, it took a little more time but I finally figured it out. The door is working and that's all that matters.

  2. Easy to hook up and set 5 Star Review

    Easy to install, I had old units that stopped working and needed to replace. Very good price and fast delivery. Thank You

  3. It does work!!! 5 Star Review

    This part number does not match what actually came. The ones that came are the newer version designed specifically for models 1997 or newer. However it does work for the models 1993 to 1997. The installation was about as easy as you could get. Took less then 15 minutes. They look more durable then the originals.

  4. Easy and quick install... 5 Star Review

    I ordered the 41A4373A Replacement Kit... Removed the old sensors and mounting brackets and installed the new ones... Lining up the sensors was quick and simple... Garage door opener was back in service in no time... Thanks, I had my doubts about the brackets at first, but once installed they were solid and well attached...

  5. Worked like a charm 5 Star Review

    I ordered the 41A4373A Replacement Kit LIFTMASTER GARAGE DOOR SAFETY BEAMS Sears Craftsman for my door because you can't find the original part any more. It worked like a charm. The hardest part was stripping the insulation off of 18yr old existing wires. It works as it should I tested it to make sure it goes back up if they is something in the way. I have not had any cold weather since I installed it. The old one would work in warm weather but not cold.
