John Schmutz, a physical security specialist at the Department of Defense Lock Program, has invented an adapter that allows the addition of a mortise lock to thick metal doors, sliding or swinging.
The patented technology is available via license agreement to companies that would make, use, or sell it commercially.

The DoD currently uses heavy, ballistic-resistant doors with increased door thicknesses that make mortise lock installations mechanically impossible.
Previous installations suffered critical failures due to complicated door or lock modifications.
This adapter provides a timely and cost-efficient solution using advanced materials and engineering designs for securing and hardening mission-critical facilities, including safes, vaults, and ammunition magazines.
Benefits
- Adapts deadlock configured mortise locks to thicker doors that exceed standard lock mounting capacities
- Provides an interior door handle
- Bolts on, reduces welding
The Opportunity
- Businesses can commercialize the technology by licensing U.S. Patent 10,415,267 from the Navy
- License fees paid to the Navy are negotiable
- Businesses that license the technology may have the opportunity to pursue collaborative research with the inventors
- TechLink guides businesses through evaluation and licensing; services provided at no cost
