The Simpson Strong-Tie DWA7G2 swivel adaptor attaches to the Dewalt DCF620 cordless screwgun so you may also use Simpson's Quik Drive QDPRO200G2 drywall system. This Quik Drive adaptor is specifically designed for drywall applications only. It rotates 360º without having to detach the tool from the motor and allows the use of one hand to rotate the tool. This adaptor also rotates screws out of the way for corner applications.
