Designed for breaker bars, this SCA Ratchet Adaptor is a very simple yet highly effective attachment. Suited for a 1/2" drive, this adaptor converts your fixed head breaker bar into a long ratchet wrench. Manufactured from chrome molybdenum steel and finished in black oxide this adaptor is made to withstand corrosion and abrasion damage and the spring ball detent retains sockets for fuss-free use. With a simple rotation of the knurled collar this adaptor switches direction to allow fast and easy tightening and loosening of fasteners.
