Buying Guide
What size cage do I need?
- Measure width and height of your outdoor condenser plus clearance for airflow and maintenance access. Choose a cage with a little extra room if possible.
What material makes sense?
- Most cages use steel or alloy steel with powder coating. Alloy steel and thicker coatings offer better corrosion resistance and longer service life in harsh weather.
How important is anchoring?
- Anchoring to concrete or the ground provides the strongest security against theft and wind. Some cages include pre-drilled holes and included screws for ease of install.
Do I need padlocks or anti-theft screws?
- Padlocks deter casual theft; anti-theft screws add an extra layer against tampering. Consider models that offer both or can be easily upgraded.
Is ease of installation a factor?
- Look for cages with straightforward assembly, clear manuals, and included mounting hardware to minimize installation time and complexity.
