Secure doors for secure rooms
Government agencies and defense contractors use SCIFs for work that has to stay classified. The door is one of the hardest parts of the room to get right, because it has to block signals and sound while still opening and locking like a door.
Duboff Locksmith Services installs both kinds of SCIF door:
- RF doors that help block radio-frequency signals from entering or leaving the room.
- Acoustical doors that limit sound passing through.
Scott installs and services Lockmasters-brand Overly SCIF doors and frames, and he works on other brands too. He services existing SCIF doors as well as installing new ones.

He is also a Lockmasters-certified GSA Authorized Safe & Vault Technician and Inspector, so the same technician can handle the GSA containers and vault doors inside the facility.
