Setup: Customizing the Foam Interior
The Pelican 1120 case includes Pick N Pluck foam for custom interior organization. This foam consists of pre-scored cubes that can be removed to create a snug fit for your equipment.
- Plan Your Layout: Arrange your items on top of the foam to determine the optimal placement. Ensure adequate spacing between items and from the case walls.
- Trace the Outline: Using a marker or chalk, carefully trace the outline of each item onto the foam.
- Remove Foam Cubes: Gently pull or cut out the foam cubes along your traced lines. Start with smaller sections and expand as needed to achieve a precise fit.
- Test Fit: Place your equipment into the customized foam to ensure a secure and protective fit. Adjust by removing more foam if necessary.

Operating the Case
Opening and Closing
To open the case, lift the two Double-Throw latches. To close, align the lid and press down firmly on the latches until they click into place, ensuring a secure seal.
Watertight Seal
The case is designed with a tongue and groove fit and a polymer O-ring to create a watertight seal. Ensure the O-ring is clean and free of debris for optimal performance.
Automatic Pressure Equalization Valve
The automatic pressure equalization valve allows air pressure to equalize between the case interior and exterior, preventing vacuum lock and making the case easier to open, especially after changes in altitude or temperature. This valve is maintenance-free and designed to keep water out.

Maintenance
- Cleaning: Clean the exterior of the case with mild soap and water. For the interior, vacuum or wipe down the foam as needed.
- O-Ring Care: Periodically inspect the O-ring for cracks, tears, or debris. Clean it with a soft cloth and apply a thin layer of silicone grease (not petroleum-based) to maintain its flexibility and sealing properties. Replace the O-ring if it shows signs of damage.
- Storage: Store the case in a cool, dry place away from direct sunlight when not in use.
Troubleshooting
Difficulty Opening the Case
If the case is difficult to open, especially after changes in altitude or temperature, the automatic pressure equalization valve may be working to balance internal pressure. Allow a few moments for the pressure to equalize. Ensure the latches are fully disengaged.
Water or Dust Intrusion
If water or dust enters the case, inspect the O-ring for damage or debris. Ensure the O-ring is properly seated in its groove and that the latches are fully closed and secured.
