The Facom Sliding T-Handle has a 1/2in Drive to fit 1/2-inch sockets or extensions. The T bar slides and has a friction head which allows the bar to be used as a T or L handle. Grooves at either end of the bar prevent it from sliding out of the drive.The long bar enables more leverage and easy two-handed use, making tightening and loosening fastenings easier.STANDARDS: NF ISO 3315, ISO 3315, DIN 3122, ASME B107.10.Specification: Length: 275mm.
