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. Use channel nuts, bolts, and washers sized for the 9/16" holes. Ensure channels are square prior to fully tightening hardware. Related Items: Strut Channel Strut Channel Hardware
