Rectangular Outlet Cast Iron Hoppers

Rectangular outlet cast iron hoppers are made for rainwater systems where the detailing needs to be right, not nearly right. These Alumasc Apex Heritage hopper heads are designed to pair with 100 x 75mm rectangular cast iron downpipes, giving the building a cleaner, more architectural finish than a standard round outlet.

They work especially well on period homes, listed buildings, churches, commercial heritage projects, and traditional developments where the rainwater goods form part of the overall façade. The rectangular outlet keeps the system consistent when used with square or rectangular downpipes, particularly alongside Moulded Ogee guttering and other sharper cast iron guttering profiles.

At Cast Iron Warehouse, we supply genuine Alumasc Apex cast iron hoppers in small and large rectangular styles, including black, primed, and custom RAL colour finishes. Every hopper in this collection is made to order, so it can be matched properly to the project rather than pulled from a generic plastic-look range.

Strong, traditional, and properly cast, these hopper heads are a small part of the system but they make a very visible difference once fitted.

Why Choose Alumasc Apex Rectangular Outlet Hoppers?

Rectangular outlet hoppers are often chosen when the downpipe below is part of the design, not tucked away out of sight. The shape gives a sharper transition from hopper head into downpipe and suits buildings with stronger vertical lines, stone detailing, decorative brickwork, or formal elevations.
