SOCKET JENIE LVSG-630 for fold down trailers that use “BAL” screw stabilizer jacks. 2'' 3/4'' x 1'' 3/8'' has 2'' 1/4'' slots across the end, with a 5/8'' hole x 1'' deep. This socket requires a 3/8” drill chuck, and can be used with a 110V or battery operated drill. Fits the small BAL type stabilizer jack the uses an acme screw to move it from and return it to the stored position. Due to the pitch of the screw threads the use of this socket with a drill moves the jack extremely fast, and caution should be used when returning it to the storage position. Because of the jack geometry and the momentum of the drill motor it will snap back into the storage position, potentially breaking the ears of the socket.
