Concealed Leaf Application

The AHDGH-224 uses a concealed-leaf full mortise design, providing the strength of a continuous geared hinge while keeping the door-side leaf concealed when the opening is installed.

This configuration provides a clean architectural appearance while maintaining heavy-duty commercial performance.

3/32" Inset

The 3/32" inset configuration provides precise positioning between the door and frame for compatible commercial openings.

Always verify the existing door and frame preparation before ordering a replacement hinge.

Door-Edge Protection Lip

The AHDGH-224 incorporates a door-edge protection lip designed to help shield the edge of the door from everyday impact, wear, and abuse.

This added protection is especially useful in high-traffic commercial environments.

• Reduced door sag

• Improved door alignment

• Reduced hinge-point stress

• Better load distribution

• Reduced stress on frame reinforcement
