Buying Guide: Key Purchase Considerations
- Security features: Look for reinforced doors, double hinges, anti-fishing panels, and robust locking mechanisms (tubular, combination, or key locks).
- Material and finish: 14-gauge cold-rolled steel and weather-resistant powder coatings withstand daily use and outdoor exposure.
- Chute and slot design: A secure, tamper-resistant chute minimizes salvage attempts; ensure the chute size matches your typical deposits.
- Wall compatibility: Check the wall thickness range and required mounting hardware to ensure proper installation without structural risk.
- Weatherproofing: If exterior, prioritize rainproof covers or weather seals to protect deposits from rain, snow, and dust.
- Accessibility: Consider whether you need a locking interior compartment for retrieval and whether a key or combination system is preferable for your group.
- Maintenance: Wire and hinges should be corrosion-resistant; choose powder-coated finishes for longevity.
