Get a quoteTechnical data

A rectangular-section gutter for larger catchments and contemporary elevations.

Profile cross-section — schematic, not to scale

Overview

A rectangular section carries more water than a half-round of the same face height, which matters on large roofs, and it reads as a straight line against a contemporary facade rather than a curve.

Available in matching fittings across the same range as the half-round system.

Applications

  • Commercial and industrial roofs
  • Contemporary residential
  • Large catchment areas
01

Higher capacity

More cross-section for the same visible face height.

02

Contemporary line

03

Full fitting range

Angles, outlets and stop ends across all sizes.
