Seam Designation: Designed for closing Angle seams and Standing seams. The flange height ($\mathbf{H}$) is $40\text{ mm}$, and the maximum fold thickness it can process is $5\text{ mm}$.

Lightweight and Compact: With a weight of only $2.8\text{ kg}$ and a length of $279\text{ mm}$, it ensures maximum maneuverability and fatigue-free operation, especially when working at height.

Spring Hammer Principle: Uses a high-frequency spring hammer action to form a high-quality and airtight joint.

Speed: An increased working speed of up to $6\text{ m/min}$ allows for fast completion of significant volumes of work.

Reliability: Despite its lightness, the tool ensures a strong and airtight seam closure, which is a TRUMPF quality standard.

TruTool F 125 Base Unit: Electric motor ($550\text{ W}$) and spring hammer mechanism.

Guidance System: Guide rail for leading the tool along the seam.

Wrenches: Necessary hex wrenches for maintenance.

Case: Robust case for safe transport.

Various Voltages: The model can be supplied for different power network standards (e.g., $120\text{V}$ or $230\text{V}$).

Specialized Heads: Additional or spare sets of tools (heads) for processing different types of seams or materials.
