MASC - Segmental eaves bender | Eaves closer

✔ Eaves folding in one step – Forms a material-friendly radius instead of a sharp edge for perfect water drainage
✔ Mark-free work without pressure marks – Even force distribution prevents imprints when repositioning the tool section by section
✔ Adjustable fold depth (20 / 25 / 30 mm) – Adjustable via screws and precisely lockable to match the specifications of the eaves flashing
✔ Modular cassette system – Base unit ($415\text{ mm}$) can be flexibly adapted to seam widths using extension segments ($100\text{ mm}$ and $150\text{ mm}$)
✔ For workshop & on-site installation – Optional offset pipe handle prevents it from hitting the gutter on steep roofs

Perfect radius at the eaves with no pressure marks

The MASC - Segment Eaves Bender is the innovative sheet metal working tool for roofers and plumbers for precisely forming the eaves fold on metal roofs. Conventional folding with pliers or hammers often creates sharp bends or unsightly crushing in the sheet metal. The Segment Eaves Bender folds the sheet metal at the eaves in a single operation, creating a precise, gentle radius. This protects against stress cracks and ensures a flawless drip edge into the gutter.

Well-designed bending geometry

Thanks to the well-designed bending geometry, repositioning the tool in sections creates no pressure marks on the visible surfaces. The fold depth can be quickly adjusted to 20 mm, 25 mm or 30 mm using the adjustment screws. Whether prefabricated in the workshop or directly on site on installed standing seam metal roofing: with the optional offset pipe handle, the eaves fold can be fully bent even on steeply pitched roofs, without hitting the already installed gutter.

Modular options & system accessories

• 415 mm base unit (Art.-Nr. STB): Solid base unit with a working width of $415\text{ mm}$ for standard panels and dormer connections.
• 100 mm extension segment (Art.-Nr. STBVS100): Two-piece segment for precisely increasing the bending width by $100\text{ mm}$.
• 150 mm extension segment (Art.-Nr. STBVS150): Two-piece segment for flexibly increasing the working width by $150\text{ mm}$.
• Offset pipe handle (Art. No. STBRB): Special handle for steep roof pitches – prevents collision with the gutter bead.

Thoughtful features for the tough day-to-day work of sheet metal workers

• Radius formation instead of a sharp bend: Prevents notch effects and cracks in zinc or aluminum structures.
• Precise depth adjustment: Fixed stops for $20\text{ mm}$, $25\text{ mm}$ and $30\text{ mm}$ seam width.
• No repositioning marks: Clean, continuous lines across the entire seam width.
• Suitable for pitched roofs: The offset handle ensures full freedom of movement above the gutter.
