- Two-piece design: The pan comes in two pieces that position around the objects to be flashed.
- Rigid wall and flange: Rigid vertical wall and preformed flange simplify membrane welding.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
Use a penetration pocket whenever multiple pipes or odd-shaped penetrations would each need individual boots, since it consolidates the flashing into one welded detail. Center the pocket on the penetrations, heat-weld the flange fully, and reinforce interior and exterior corners to avoid cold welds. Verify penetration material compatibility with TPO before installation.
Hot-air welding equipment presents burn and fire hazards; follow the tool manufacturer's safety instructions and inspect all welds after cooling.
Add the Johns Manville TPO Penetration Pocket to your TPO job to flash difficult penetrations quickly and reliably.
