The perforating head weakpoint is a mechanical weakpoint that can be used as a primary or backup release mechanism. Providing a mechanical weakpoint in the head can eliminate the need for ballistic or electrical release devices, or provide a redundant release mechanism if still required.
The best part? These weakpoints can be changed out without re-heading.
For more details on where the weakpoint fits into an effective assembly, check out the attached manual for several helpful, visual examples.
