This Posi Lock 10661 slide rod adapter is for use with the 106 and 206 pullers (sold separately), which remove shaft-fitted parts and reduce the force required to dismount the parts. The slide rod adapter works with the slide rod and slide hammer to create additional manual force when pulling. It is constructed of steel to help prevent rust and corrosion. A Posi Lock puller is suitable for extracting bearings, wheels, bushings, gears, and pulleys in applications in the automotive, agricultural, and manufacturing industries.
