We are a noted manufacturer of 1-4inch Quick Release Ratchet in the market. It typically has a lockable ball detent which requires a press on the back of the ratchet head to release a socket. An accidental push of the release button can result in unpleasant consequences if a socket then falls into a busy workspace, such as an engine bay. Our offered 1-4inch Quick Release Ratchet goes through several quality checks prior to the final dispatch from our unit.
