FAQs HydroLockers®
What makes HydroLockers better than fiberglass dock boxes?
Fiberglass fades, cracks, and requires constant upkeep. HydroLockers are built from marine-grade polyethylene that never needs painting or refinishing — they simply last longer.
Can HydroLockers be left outside year-round?
Yes. They’re engineered for permanent outdoor use in any climate, from blazing sun to freezing winters.
Can I lock my HydroLocker?
Absolutely. Every model includes secure hasp systems for standard padlocks, with vandal-resistant hinges for extra protection.
Do HydroLockers require maintenance?
No. Just rinse with fresh water as needed — they will not rot, rust, or degrade like wood or fiberglass.
Can I use HydroLockers for electronics or sensitive gear?
Yes. Their water-resistant designs protect contents from rain and splash, keeping your gear safe and dry.
