Core Configurations & Installation Parameters
Hardware Specifications
- High-Tensile Aluminum Body: Fabricated from solid extruded aluminum alloy to resist shear, bending, and dynamic impact forces. The structural barrier is engineered to withstand up to 800 lbs of force, effectively defending doors against kick-in attempts.
- Inward-Swinging Door Requirement: Designed strictly for interior jamb mounting on inward-opening doors. When engaged, the aluminum locking bar physically overlaps the door panel face, preventing the door from opening even if the primary deadbolt is compromised.
- Door Trim & Frame Clearances: For correct latching, the surrounding door casing or decorative trim must sit flush with the door plane, or project no more than 5 mm above the door face.
- Excluded Door Configurations: Not compatible with double doors (without a structural center mullion), sliding pocket doors, or paired French doors.
- Surface Finishing Options: Available in electroplated or anodized Silver and Gold finishes to complement common residential and hotel door trim suites.
Operating Mechanism (Lock & Unlock Steps)
The DR-10 features a dual-action spring-loaded retention mechanism that prevents accidental release and cannot be bypassed from the exterior:
- Pinch: Squeeze the spring-loaded middle bump on the upper and lower tabs simultaneously.
- Pull: Slide the mechanism laterally toward the door panel to clear the frame retention detent.
- Swing: Pull the lock body outward toward yourself, rotating the bar away from the door face.
- Rest: Allow the lock body to swing fully open parallel to the door frame to permit unobstructed door entry and exit.
Primary Application Environments
- Residential Perimeter Protection: Supplementary defense on exterior front, back, and garage access doors against physical kick-in attacks.
- Child & Toddler Safety: Installed above child reach on exterior and basement doors to prevent unsupervised exit.
- Elder & Pet Safety: Serves as an interior wandering barrier for residential care and family homes.
- Hospitality & Rental Units: Interior-only occupant privacy lock providing peace of mind for hotel guest rooms and rental properties.

Frequently Asked Questions
The lock mounts directly to the frame jamb and overlaps the face of the door panel to block inward movement. If a door swings outward, the lock cannot obstruct it. If the decorative trim projects more than 5 mm beyond the door surface, the locking arm cannot pivot flat against the door panel.
No. The DR-10 is a non-keyed interior auxiliary security lock. It can only be engaged and disengaged manually from inside the room, providing protection that cannot be picked or bumped from the exterior.
The DR-10 cannot be installed on sliding patio doors, paired French doors, or standard double doors lacking a fixed central frame mullion, as these doors do not provide the stationary frame stop required for anchoring.
