1. Introduction
This manual provides instructions for the installation, operation, and maintenance of the ABUS 140/120 Stainless Steel Security Hasp. This hasp is designed for enhanced security, featuring stainless steel construction and hardened components to resist corrosion and forced entry.

2. Setup and Installation
Proper installation is crucial for the security and longevity of your ABUS 140/120 Hasp. Ensure you have appropriate mounting hardware (screws, bolts) suitable for your door/gate and frame material. The hasp is designed with hidden screws to prevent tampering once installed.
2.1 Required Tools
- Drill
- Drill bits appropriate for mounting hardware
- Screwdriver (manual or power)
- Measuring tape or ruler
- Pencil or marker
- Safety glasses
2.2 Installation Steps
- Positioning: Determine the optimal placement for the hasp on your door/gate and frame. Ensure the two parts of the hasp align correctly when the door/gate is closed. The hasp should be mounted on a flat, stable surface.
- Marking Screw Holes: Hold the hasp base (the larger, hinged part) against the door/gate and mark the screw hole locations with a pencil. Repeat for the staple plate (the smaller part with the loop) on the frame.
- Drilling Pilot Holes: Drill pilot holes at the marked locations. The size of the pilot holes should be slightly smaller than the diameter of your mounting screws to ensure a secure fit.
- Attaching the Hasp Base: Secure the hasp base to the door/gate using appropriate screws. Ensure it is firmly attached and does not wobble.
- Attaching the Staple Plate: Close the door/gate and align the staple plate with the hasp base. Ensure the staple (the loop for the padlock) passes through the opening in the hasp base without obstruction. Mark and drill pilot holes for the staple plate, then secure it with screws.
- Testing: Once both parts are securely mounted, close the hasp and ensure a padlock can be easily inserted and removed. Verify that the hasp is securely fastened and cannot be pried open without significant force. The design includes hidden screws, meaning once a padlock is in place, the mounting screws are not accessible.

3. Operating Instructions
The ABUS 140/120 Security Hasp is designed for straightforward operation in conjunction with a suitable padlock.
3.1 Locking the Hasp
- Ensure the door or gate is fully closed.
- Align the hinged part of the hasp over the staple plate.
- Insert the shackle of your padlock through the staple loop and the corresponding opening in the hasp.
- Close and lock your padlock according to its specific instructions. Once locked, the hasp's mounting screws are concealed, preventing unauthorized removal.
3.2 Unlocking the Hasp
- Unlock your padlock using its key or combination.
- Remove the padlock from the hasp.
- Swing the hinged part of the hasp away from the staple plate to open the door or gate.
4. Maintenance
The ABUS 140/120 Hasp is constructed from stainless steel with zinc-coating, offering excellent resistance to corrosion and requiring minimal maintenance.
- Regular Cleaning: Periodically wipe down the hasp with a damp cloth to remove dirt, dust, and debris. For stubborn grime, a mild soap solution can be used, followed by rinsing and drying.
- Inspection: Annually inspect the hasp for any signs of wear, damage, or loose mounting screws. Ensure the hinge operates smoothly. Tighten any loose screws immediately.
- Lubrication (Optional): While not typically required for the hasp itself, if using a padlock, follow the padlock manufacturer's recommendations for lubrication to ensure smooth operation, especially in outdoor or harsh environments.
- Corrosion Prevention: Although made of stainless steel, prolonged exposure to highly corrosive environments (e.g., saltwater spray) may eventually show signs of surface discoloration. Regular cleaning helps mitigate this.
5. Troubleshooting
This section addresses common issues you might encounter with your security hasp.
5.1 Hasp Does Not Close Properly
- Check Alignment: Ensure the door/gate is fully closed and the hasp components are correctly aligned. Misalignment during installation can cause issues.
- Obstructions: Look for any debris or foreign objects preventing the hasp from closing smoothly.
- Loose Screws: Verify that all mounting screws are tight. Loose screws can cause the hasp to shift out of alignment.
5.2 Difficulty Inserting Padlock
- Padlock Shackle Size: Confirm that your padlock's shackle diameter is compatible with the hasp's staple. The maximum shackle diameter for this hasp is 7/16 inch.
- Hasp Alignment: Ensure the hasp is fully closed and the staple loop is perfectly aligned with the opening in the hasp body.
5.3 Signs of Rust or Discoloration
- Surface Contamination: Even stainless steel can show surface rust if exposed to iron particles or certain chemicals. Clean the affected area thoroughly with a non-abrasive cleaner and a soft cloth.
- Environmental Factors: In extreme marine or industrial environments, some surface discoloration is possible over time. Regular cleaning and inspection are recommended.
