Lockable RPZD / Backflow Protection Cage

Australian Made – Custom Fabricated Steel

Protect critical water infrastructure with a purpose-built, lockable steel protection cage designed for RPZD units, backflow preventers, water meters and valve assemblies.

These cages are fabricated in Australia using heavy-duty steel, welded mesh and secure locking points to prevent vandalism, accidental damage and unauthorized access — while still allowing easy servicing when required.

Built from real-world plumbing experience, this design has been installed and proven onsite.
