The 45 degree flat bend softens a direction change instead of forcing a hard corner. On facades with angled walls, bay windows or sloping eaves, two of them plus a short straight section make a clean 90 degree offset where a single elbow would look abrupt.

Q: When should I use a 45 degree bend instead of a 90 degree elbow?
A: When the wall geometry changes direction gradually, or when the corner should look softened rather than square.
Q: Can two bends make a 90 degree offset?
A: Yes. Two 45 degree bends with a short straight section between them create an offset that clears a ledge or pillar.
Q: Which widths are available?
A: The bend is produced for the 75, 100, 130 and 160 mm profiles.
