Qiyi Fastener lists CC-15-77-30 as a concealed 3-way corner connector for 3030 profiles, modular furniture, cabinets, shelves and storage frames. This zinc alloy corner connector is designed to sit inside a three-way joint so the finished assembly can keep a clean, low-visibility appearance. Confirm the profile, joint geometry and fastening method before ordering.
Use the complete part number when sourcing a hidden corner bracket, concealed furniture connector, 3030 profile corner fitting or three-way aluminum profile connector. The related 4040 model is a different part and should not be substituted without a fit check.

Applications for a Hidden Three-Way Corner Bracket
CC-15-77-30 can be reviewed for concealed three-way joints in modular furniture, cabinet frames, shelves, storage units and 3030 aluminum profile assemblies. As a 3030 profile corner connector, its hidden format is useful where the visible faces should remain uncluttered after assembly.
- Concealed cabinet corner connector for three-way frame joints
- Hidden shelf connector and modular furniture corner fitting
- 3030 aluminum extrusion corner connector for frame assembly
- Silver zinc alloy corner bracket for a low-visibility furniture finish
Application suitability depends on the profile, joint direction, mating fasteners, furniture loads and service environment. Confirm the complete design before use.
How to Select and Install a Concealed 3-Way Connector
Before choosing a concealed furniture connector, verify that the profile is 3030 and that the connector geometry matches the three-way joint. A similar-looking 4040 corner bracket or two-way connector is not automatically interchangeable.
- Confirm the extrusion or frame profile and joint orientation.
- Compare the connector dimensions with the internal profile space and access points.
- Confirm screw type, thread engagement, tightening access and whether fasteners are supplied.
- Check alignment, corner clearance and the complete assembly load before final installation.
The listing describes concealed installation but does not provide an installation torque, allowable load or itemized hardware list. Request the controlled drawing and installation requirements before production assembly.
Custom Concealed Corner Connector Options
For a custom hidden corner bracket or modified aluminum profile connector, provide the profile section, joint angle, dimensions, material, finish and fastener requirements with the drawing.
