Two Liftmaster 971LM transmitters. These work for slightly older Liftmaster, Chamberlain or Sears Craftsman door openers. They are rolling code 390mhz (current models are 315mhz). If your opener has a white, yellow or red "learn-button" these will work...not compatible with purple button models. One in box other out of box. Both like new - never used. Shipped conus for $25 for both. Paypal only. Trade for whatever you have that might strike my fancy. Cheers!
