Hager 780-112HD 83 Dba RETW-10 Lh Continuous Geared Hinge

Product Description

The HAGER 780-112HD 83 DBA RETW-10 LH is a concealed leaf continuous geared hinge designed for left-handed door applications requiring heavy-duty performance. At 83 inches in length, this full-height hinge spans the entire door edge to distribute load evenly across the frame, reducing stress points and extending door and frame life. The dark bronze anodized aluminum finish provides corrosion resistance suited to high-traffic commercial environments. It includes a removable 10-wire raceway, making it a practical choice when low-voltage wiring must pass through the door-frame junction. Licensed contractors and commercial door hardware installers are the typical end users.

This hinge is intended for commercial door installations where a full-length continuous hinge is specified in place of multiple individual hinges. The left-hand designation applies to doors that are hinged on the left when viewed from the pull side. The 83-inch length accommodates standard commercial door heights. The removable 10-wire (RETW-10) feature supports electrified hardware applications such as access control, electric strikes, or door position monitoring, allowing wires to route cleanly through the hinge without exposed conduit.

Key Features

• Full 83-inch concealed leaf design distributes load along the full door height
• Geared continuous hinge construction for smooth, consistent operation under heavy use
• Left-hand (LH) configuration for left-hinged door installations
• Removable 10-wire raceway (RETW-10) supports electrified hardware and access control wiring

• Heavy-duty (HD) rating suited for demanding commercial door cycles

Compatibility

Designed as an OEM-style continuous geared hinge replacement or new installation component for standard commercial hollow metal or wood doors requiring a left-hand, full-height hinge with integrated wire management.

Installation Notes

Installation is typically performed by a commercial door hardware technician or licensed general contractor familiar with door and frame prep requirements. The door and frame must be properly mortised to accept the concealed leaf profile before fastening. Electrified wire routing through the RETW-10 raceway should comply with applicable NEC requirements for low-voltage wiring. Ensure all access control circuits are de-energized before routing or connecting wires through the hinge assembly.
