Steel Protection Backflow Preventer Security Cage — Large
Guardian Enclosures’ Large backflow cage uses sturdy 1 ½” tubing, #13 gauge expanded metal, and reinforced angle iron to create a durable security cage for outdoor backflow preventers.

Buying Guide: Key Purchase Considerations And Comparisons
When selecting a backflow cage, assess size, security, and environmental exposure to determine the best fit:
- Size and compatibility: Measure the backflow preventer assembly, including height, width, and length, with extra clearance for accessibility during maintenance. Choose a cage with internal dimensions that accommodate the unit and required service space.
- Security features: Look for reinforced steel construction, diamond-pattern metal panels, and a robust locking system. A padlock-ready design (3/4” shackle) improves theft resistance, particularly in public or semi-public areas.
- Maintenance access: Ensure the cage provides convenient access points for routine inspections, valve adjustments, and filter replacements. Easy lift-off panels or access doors are beneficial in daily workflows.
- Weatherproofing and durability: Powder-coated finishes, sandblasting preparation, and corrosion-resistant materials extend the cage’s lifespan in sun, rain, and temperature extremes.
- Installation footprint: Consider site constraints such as ground level, drainage, and proximity to water sources. A larger cage offers future-proofing if system upgrades are planned.
- Color and appearance: For installations in aesthetically sensitive areas, color-matched or tan options can help the cage blend with surroundings while preserving function.
Comparative snapshot:
- Largest models provide greatest internal space for bulky backflow assemblies and service clearance but require more footprint.
- Mid-sized cages balance footprint with ample maintenance access, suitable for typical residential or commercial sites.
- Small and extra-small cages fit tight spots, though may limit future expansion or large backflow units.
- All Guardian Enclosures models emphasize security, weather resistance, and long-term durability, making them suitable for outdoor installations across varied climates.
