Rectangle Rainhead

The rectangle rainhead is a box-style conductor head that connects the box gutter to the downpipe. It creates a vertical drop between the two, which gives the water headroom and stops the box gutter from overflowing inside the building in a heavy downpour. It is formed in 0.55mm BMT Colorbond or Zincalume steel, and the clean rectangular shape suits modern rooflines and box gutters.

Installation

Mount the rainhead at the box gutter outlet and set the overflow weir 25mm below the gutter sole so excess water sheds before the gutter backs up. Match the weir width to the rainhead inlet, then connect the downpipe to the fitted outlet. The rectangular form sits flat against the wall and keeps the downpipe line clean.

Applications

• Box gutter terminations on residential and commercial buildings
• Internal gutters that need overflow protection in intense rainfall
• Downpipe connections where a neat rectangular head is wanted
• Modern and traditional roof styles, Colorbond or Zincalume finishes

Frequently Asked Questions

What is a rectangle rainhead for?

It connects the box gutter to the downpipe and creates a drop between them. That drop gives the water room to fall and stops the gutter overflowing inside the building when rain is heavy.

Why does the overflow weir sit below the gutter sole?

AS/NZS 3500.3:2003 specifies that the overflow weir be positioned 25mm below the gutter sole, with the width matching the rainhead inlet. That way the weir sheds water before the gutter level reaches the top.

What sizes are available?

The standard range runs from 300 x 200 x 200mm up to 600 x 200 x 400mm. Bespoke dimensions are made on request for unique gutter requirements.

Can I get an overflow spout?

Yes. The overflow spout is optional and must be specified at the time of order. It is available in round, square or rectangular shapes to suit the downpipe style.
