Drop Lock Ball Keeper

This feature when activated allows you to walk normally without the fear of the knee lock accidentally engaging.  It is a totally manual operation where the drop lock is physically pushed over the ball to engage or disengage the knee joint lock.  It is a very reliable and basic means of controlling the knee joint and provides years of trouble free service.  This feature is also recommended for hip joint locks if you're considering HKAFO's.

$15 Per Joint
