Choose the Correct Fit
Match the 3/8 in drive to the ratchet and socket. Check the available space for the complete assembly.
Seat both connections fully before turning. Verify that the socket remains secure when withdrawing it from a recess.
Installation & Care
Position the joint at the smallest angle that clears the obstruction. Stop turning if the joint starts to bind.
Remove oil and grit after use. Inspect the connection corners and moving parts, then store the accessory dry.

Important Product Questions
Will this adapt to a different drive size?
No. Match both the tool and socket to the 3/8 in drive. A universal joint changes the approach, not the connection size.
Can I use it on an impact wrench?
Choose a separately verified impact-rated joint for impact work. A chrome hand-tool joint should not be assumed suitable for impact use.
How much angle should I use?
Use the smallest angle that clears the obstruction. Check that the joint moves freely and the socket remains fully seated before applying force.
