Maintenance
- Cleaning: Wipe the exterior with a soft, damp cloth. Avoid abrasive cleaners that could damage the finish. The interior can be vacuumed or wiped to remove dust and debris.
- Lock Care: Periodically apply a small amount of graphite lubricant to the keyhole to ensure smooth operation. Do not use oil-based lubricants.
- Check Mounting: Regularly inspect the fastening hardware to ensure the cabinet remains securely mounted to the floor or wall. Tighten any loose bolts as needed.
Troubleshooting
- Key is Stiff or Stuck: Apply graphite lubricant to the keyhole. Gently wiggle the key while turning. Do not force the key, as this may cause it to break.
- Door Does Not Close Properly: Check for any obstructions inside the cabinet or along the door frame. Ensure the cabinet is on a level surface and securely mounted.
- Limited Storage Capacity: While rated for 22 guns, actual capacity may vary depending on the size and type of firearms, especially those with scopes or accessories. Optimize space by adjusting the removable shelf and carefully arranging firearms.
