Thanks everyone
Thanks for all the help! We were originally going to trash them until we found that they worked. We already have a pair so we were going to sell them for $50 a piece, then the cable guy said they were cool and he likes to fix them up. Said he would call us the next day but...
Just bought our first home, and a washer and dryer was left. Does anyone know anything about these items? Had someone tell us that it's hard to find ones like this in working condition. Curious! Please help.
