National Marker N183780 Keyed Different Hasp Lock

Product Description

The NATIONAL MARKER N183780 is a self-contained keyed different hasp lock built for securing doors, cabinets, boxes, trunks, and similar enclosures. At 4.5 inches in length and constructed from heavy steel with a chrome-plated finish, this lock eliminates the need for a separate padlock. All screws are covered when the lock is in the closed position, preventing tampering with the mounting hardware. It ships with 2 keys and all required mounting hardware. Suitable for both indoor and outdoor installations.

This hasp lock is appropriate for light commercial and residential applications where a built-in locking mechanism is preferred over a separate padlock. Typical uses include tool cabinets, storage boxes, utility enclosures, and equipment trunks. The keyed different configuration means each unit operates on its own unique key, making it a practical choice where individual access control is needed across multiple enclosures. The key blank for this version is SL-1 or the ILCO equivalent 1120D.

Installation Notes

Installation is typically performed by a general contractor, maintenance technician, or qualified DIYer using standard hand tools. Mount the hasp to a clean, flat surface using the included hardware, ensuring all screws are properly seated before closing and locking the hasp. Verify the strike plate and hasp align correctly before final tightening. For outdoor applications, confirm the mounting surface is suitable for exterior use to maintain the integrity of the chrome finish over time.
