Triangular Plastic Strip with Feather
Triangular plastic strip (feather) – 45° chamfer for concrete edges
The triangular plastic strip (feather) forms clean 45° chamfers on concrete edges, providing stable positioning in the formwork and consistent, neat corners after stripping.

Description
The triangular plastic strip (feather) is a disposable polyethylene chamfer used to shape and protect concrete edges at a 45° angle. Its triangular cross‑section creates a uniform chamfer on columns, walls, parapets and foundations, while the additional feather (tongue) allows the strip to be inserted between formwork panels, significantly improving stability during concreting. The impact‑resistant polyethylene does not crack during fixing and remains dimensionally stable under fresh concrete pressure. Pre‑formed fixing holes enable quick nailing or screwing to the formwork, ensuring precise alignment in the corner. After the concrete has hardened and the formwork is removed, the strip is taken out, leaving a straight, clean, chamfered edge without additional grinding. The design is suitable for both wall and foundation formwork systems.

Application
The triangular plastic strip (feather) is used on reinforced concrete projects wherever durable and aesthetic edge chamfering is required:
- construction of columns, walls and parapets – forming 45° chamfered edges with increased resistance to damage,
- improving aesthetics and safety – chamfered corners reduce chipping and eliminate sharp edges,
- formwork for foundations and concrete walls – convenient chamfering of edges in wall and foundation formwork systems,
- use with formwork panels – the feather allows the strip to be locked between panels for stable positioning,
- applications requiring chamfered concrete edges on visible elements such as columns, walls, beams and plinths.
Technical parameters
- Purpose: disposable chamfer element for shaping 45° concrete edges.
- Material: polyethylene, resistant to damage during fixing and concreting.
- Geometry: triangular strip with additional feather for insertion between formwork panels.
- Single strip length: 2.5 m (based on packing data).
- Cross‑section dimensions (triangle legs) and packing:
- 10/10 – 100 m per pack (40 strips x 2.5 m),
- 15/15 – 100 m per pack (40 strips x 2.5 m),
- 20/20 – 100 m per pack (40 strips x 2.5 m),
- 25/25 – 50 m per pack (20 strips x 2.5 m),
- 30/30 – 50 m per pack (20 strips x 2.5 m).
- Fixing: through mounting holes and/or by inserting the feather between formwork panels.
