Why Custom RPZD & Backflow Protection Cages Matter

by kyle Sevenoaks December 31, 2025

Backflow prevention devices and RPZD assemblies are critical pieces of plumbing infrastructure. When they’re left exposed, they’re vulnerable to vandalism, accidental damage, and unauthorised access — especially in public or commercial environments.

At Stick-Dat, we fabricate custom steel RPZD and backflow protection cages designed to suit real-world installations, not generic off-the-shelf dimensions.

Not Every Installation Is the Same

Anyone who works in plumbing knows this simple truth:
no two installs are ever identical.

Pipe heights vary. Valves are offset. Drains, walls, slabs and services rarely line up with catalogue dimensions. That’s why fixed-size cages often cause problems — blocked access, awkward servicing, or the need for site modifications.

Our cages are built to suit your installation, not the other way around.

What Makes a Custom Cage Different?

When we fabricate a cage, we can adjust key features to match your layout, including:

Lid position (centered or offset)
Hinge direction for easier servicing
Pipe and drain clearances
Mounting tab locations
Overall width, height and depth
Locking points and access panels

This ensures the cage protects the equipment while still allowing plumbers and technicians to service it properly.

Designed for Service Access

A protection cage shouldn’t make maintenance harder.

Our RPZD cages feature hinged lids that allow access without removing the entire enclosure. This reduces service time, avoids unnecessary unbolting, and keeps compliance checks quick and simple.

The open-bottom design also allows proper drainage and visual inspection where required.

Built from Steel, Made in Australia

Every cage is fabricated locally using:

Steel angle frames
Heavy-duty welded mesh
Lockable hasp and staple
Solid wall mounting tabs

Welds are finished and protected, and optional hot-dip galvanising is available for harsh or coastal environments.

These are built for commercial use, not light-duty applications.

Custom RPZD and backflow cages are ideal for:

Commercial plumbing installations
