sw mn | I believe they are called an offset extension and they are approximately 1/2 inch wide + or- and are 12 to 18 inches long and they have 2 gears inside that have a # 40 roller chain between them to transfer the power from one end to the other so they can supposedly get into a spot that a wrench can only get into. They look interesting but question how long the gears and the roller chain would last. | |
