My buddy has Legacy brand overhead garage door opener. He is not too handy, so I figured I would help him out, since he is my business partner too. Looks like his safety sensors (kid-catchers, as I call them) went bad due to some moisture issues (and they were old). I think he should skip buying a new opener and just get replacement sensors instead. I can't find Legacy brand anymore. Do you know what other I could substitute with? Are those pretty much universal?
