Key Advantages

-Additional Interior Door Security
The ST.GUCHI DG-002 provides an additional fastening point on the inside of a compatible door. When properly installed and engaged, it helps restrict door opening, making it a practical supplementary security fitting to use alongside the main door lock.

-Controlled Partial Door Opening
The D-shaped swing-bar arrangement allows a compatible door to be opened partially while the guard remains engaged. This provides a limited opening for speaking with someone outside without immediately opening the door fully. The actual opening distance depends on the installation position and door geometry.

-Manual Swing-Bar Operation
The movable guard arm allows users to engage or release the fitting manually from inside. Its direct mechanical operation requires no batteries or electrical connection, making it convenient for everyday use as part of a door-closing routine.

-Chrome and Antique Finish Options
Available in Chrome and Antique finishes to coordinate with different door handles, locks and surrounding fittings. Chrome offers a bright metallic appearance, while Antique provides a warmer, traditional look for matching door hardware and interior designs.

-Practical for Compatible Installation and Replacement
Suitable for adding a supplementary door guard or replacing an existing fitting when the mounting conditions match. Checking the door opening direction, frame alignment, mounting space and fixing points helps installers determine compatibility and position the guard correctly.

Broad Range of Applications
-Compatible Inward-Opening Wooden Doors, Compatible Inward-Opening Metal Doors, Residential Entrance Doors, Apartment Entrance Doors, Selected Room Doors, Office Doors, Homestay Doors, Hostel Room Doors, Interior Door Security Upgrades, Compatible Door Guard Replacement, Renovation Projects, Property Maintenance
