751 Slide-A-Mark Heavy Duty holder retention

Customers with the Slide-A-Mark air impact marker sometimes have problems with the quick change holder coming loose.  There are many factors that can contribute to the loosening, incorrect orientation of the ball lock, the holder is not flush when the ball lock is tightened, dirt or debris may be contaminating the mating surfaces to name a few.  CMT has a simple solution that may help, the medium and heavy duty ball lock option.  By adding a lock nut to the ball lock assembly, the customer can insure there is no possibility of the ball lock backing out or loosening during operation.    Please click the following link for example:   751K-RETENTION
