safety sensor eyes universal

I installed these universal sensors and they worked well with my 1994 LiftMaster opener.
However, the one piece mounting brackets that came with it were too short to move the eyes past the door hardware. I had to screw them onto the old brackets. The old bracket were two part which allowed you to set the depth. Maybe you should consider using this type of hardware.
I like the fact that these units were manufactured in the U.S.
