The A6 series are assembled on a 7-11/16 in. OD, 3-1/4 in. ID, 31 in. long heavy-duty sub, which adds 30 in.to the drilling assembly.
 

The proprietary B7 Series Kelly Spinners are designed for smaller rigs where there is no room for an additional 30 inches in the assembly. In this new series the Kelly Spinner attaches to the bottom of the swivel so no additional length is added.
