Description
The Proto Seam Test Tool with 17" shank is a hand-held probe used to check the integrity of heat-welded or adhered seams on single-ply roofing membranes (TPO, PVC, EPDM). The extended shank lets crews test seams without bending or kneeling across the full width of a lap.
- 17" shank reaches across wide seam laps for full-length testing
- Simple hand-probe design for quick pass/fail seam checks
- Useful for quality-control walks on newly welded or adhered seams
