Roll the seam and check it in one pass. Steel roller one end, seam probe the other.
Pressure Roller Large Penny with Probe is a two-in-one hand tool: a round edge steel pressure roller and an angled seam tester with a probe hook, on a wooden handle. Roll the seam on thermoplastic membrane, then run the hook along the lap to check the weld.

No documentation available for this product.

Correct application makes all the difference.
Forspec publishes no data sheet, dimensions, safety information or PPE guidance for this tool. The probe is a sharp hook, so handle and store it accordingly. Seam probing is a check on a weld, not a substitute for the test regime in the membrane Technical Data Sheet. Roll and test to the membrane manufacturer's requirements, not to the tool.

The Pressure Roller Large Penny with Probe is a specialty detail tool combining a larger 'penny' roller for corners and small areas with a probe tip for working membrane into tight penetrations and irregular junctions.
The probe tip is used to push liquid membrane or sealant into pipe penetrations, drain collars, and irregular cracks where rollers can't reach. Critical for achieving full coverage at the most leak-prone details.
Press the penny roller into wet membrane at corners and around penetrations to embed reinforcement tape or mesh - the larger penny disc covers more area per pass than smaller detailing rollers.
Used across the ACTFLEX detailing workflow: ACTFLEX 906 WPU, 929 HV, 925, 988 CWP with Leak Tape, SA TAPE, MESHTAPE, FLEXTAPE, and AT-MESH at corners and penetrations.
Clean immediately after use - solvent for polyurethane membranes, water for water-based products. The probe end especially needs cleaning since dried product makes it less effective at penetrating tight details.
