The tool features a handle marked with the part
number, a contact lance release tip, locking lance
reset portion, and tool stop. The contact lance release
tip is designed to depress the contact locking lance to
allow extraction of the contact. The tool stop prevents
over-insertion of the tip. The lance reset portion is
designed to reposition an overly depressed locking
lance to the proper height assuring retention of the
contact in the housing.
