They are open 7 days a week. 8 to 6pm I think. From 70 east, you need to go to 71, go south on 71 get off at the Frank Rd exit. Turn right, go straight it will turn into 104. Go I think 3 exits and it's Groveport Rd exit. Get off and turn right, then about half mile on your left you'll see U Wrench it.
