This standard ratchet kit does not have a quick release feature, making it durable and reliable for automotive mechanics and DIY enthusiasts alike. The manufacturer part number RKRF80 indicates compatibility with 3/8 inch drive sizes, ensuring a perfect fit for various ratchet models.

All other parts are brand new unused.
