Description
Fort Knox Vault Door
Turn a secure room into a full vault with the Fort Knox Vault Door, available in both In-Swing (internal hinge) and Out-Swing (external hinge). The system features a rugged 3/16" body/frame, a reinforced 5/8" door edge, and heavy-duty boltwork (size-dependent). Standard sizes include 82" or 96" heights and 40" or 48" widths with published rough-opening and overall frame dimensions for clean planning with your builder.
Key Benefits
- Engineered Strength: 3/16" face frame thickness clamps directly to concrete; 5/8" door edge adds rigidity and pry resistance.
- Swing Options & Hinge Choice: In-Swing (internal hinge) for storm shelters/panic rooms or tight exterior clearances; Out-Swing (external hinge) gives a 180° swing radius for maximum room access. Left- or right-hinge configurations available.
- Size Flexibility: Four standard sizes (8240, 8248, 9640, 9648) fit new builds and remodels; custom sizes available.
- Contractor-Friendly Specs: Published Rough Opening and Including Frame dimensions reduce guesswork; we coordinate directly with your contractor.
- Security-First Design: Extensive perimeter boltwork by size/swing (see table) for confident engagement into the frame.
Planning & Installation Notes
- Rough Opening: Measure height & width of the rough opening; accurate measurements are the customer’s responsibility to ensure fit and protection.
- Wall Thickness: Measure concrete wall thickness in three places; typical poured-concrete measurements are 6"–12" (round up to the nearest inch).
- Face Frame Clearance: Leave at least 4" clearance around the opening; clear both sides of the opening inside and out.
- Surface Prep: Remove wood framing and imperfections so the face frame can clamp directly to smooth concrete for maximum security and fire protection performance of the finished room assembly.

Frequently Asked Questions
Are Vault Doors fire-rated?
The door itself lists N/A for a standalone fire rating; overall fire performance depends on the entire room assembly (concrete, wall build, and door clamp). We’ll share best practices for your contractor.
Which swing should I choose?
In-Swing (internal hinge) is ideal when the door must not block exterior hallways and for storm/panic rooms. Out-Swing (external hinge) offers a 180° swing radius and keeps the interior clear for cabinetry and racks.
Can I pick left or right hinges?
Yes — both left and right hinge orientations are available for In-Swing and Out-Swing doors.
What site prep is required?
Measure concrete wall thickness in three places, leave 4" clearance around the opening, and remove any wood forms/imperfections so the face frame clamps directly to smooth concrete.
Do you offer custom sizes?
Yes, custom sizes are available. We’ll review the opening and provide options based on your build.
