Buying Guide: Key Considerations When Choosing Truck Cap Locks
What is my installation type and mounting pattern? Confirm hole sizes and the exact position of mounting holes to match your cap’s design. Some kits require 1-1/16″ or similar specs, while others specify 1-5/8″ shaft lengths.
Should I choose a single-key system? If you want convenience across multiple latches, a universal key system or key-alike sets reduce key clutter and loss risk.
What materials matter for weather resistance? Look for zinc alloy or powder-coated finishes for rugged outdoor exposure and longer life in varying climates.
Do I need left/right specific locks or a complete set? Some kits provide L/R pairs, while others include both sides plus extras—assess whether a full set or single replacements fit your needs.
Is installation complexity a factor? Some kits are straightforward DIY installs with screw-through mounting; others require precise alignment of cam directions. Choose based on your comfort with minor adjustments.
