Buying Guide
How to choose the right exterior RV storage lock:
- Lock size: Measure the locking distance from the door face to the latch position and verify door thickness. Choose a size that matches the measured distance to ensure proper engagement.
- Mounting compatibility: Check the hole diameter and backset. Most locks use a ¾” (0.75″) double D hole opening; ensure your door’s holes align with this standard.
- Keying options: Decide if you want keyed-alike sets for multiple compartments. Packages that include the same key for all locks simplify access, but note that multiple sets may have different key codes.
- Material and weather resistance: Look for stainless steel or zinc alloy components for durability in sun and rain. A weather-resistant finish extends lock life on exposed RV compartments.
- Replacement vs. upgrading: When replacing old locks, compare backset, cylinder length, and mounting hole spacing to avoid mismatches with your existing hardware.
- Installation notes: Some locks include CAM plates or mounting accessories. Ensure you have the correct tools and a clean mounting surface for reliable operation.
