4-Hole Corner Gusset – Electro-Galvanized
The 4-Hole Corner Gusset – Electro-Galvanized is designed to reinforce 90-degree strut channel intersections where added strength is needed. With increased surface area compared to standard flat corner fittings, it helps distribute loads more evenly while maintaining a flush, low-profile connection. A solid choice for interior framing systems that require extra rigidity at corner joints.
Electro-Galvanized 4-Hole Corner Gusset for Strut Channel Framing
This corner gusset sits flat across the top of two strut channel lips meeting at a right angle. Featuring 9/16″ punched holes, it allows for secure fastening using standard channel hardware in dry, low-humidity environments.
Key Features
- Increased Surface Area: Provides greater load distribution than traditional flat corner plates.
- Flush 90 Degree Fit: Sits cleanly on top of channel lips at corner intersections.
- Four Punched Holes: Includes 9/16″ holes for consistent, secure fastening.
- Electro-Galvanized Steel: Intended for interior applications with minimal moisture exposure.
Common Applications
- Reinforced strut channel corner framing
- Electrical and conduit support systems
- HVAC and mechanical assemblies
- Interior utility support structures
- Commercial build-outs and retrofits
Installation Tips
- Position the gusset evenly across both channel lips before fastening.
