Eaton 516 HDG Rigid/IMC Clamp - Hot Dip Galvanized
Part Number: 516 HDG
Quick Summary
516 HDG is a rigid/IMC conduit clamp designed for securing IMC or rigid conduits in electrical installations. In the field, corrosion and loosening hardware can lead to downtime and safety concerns. This clamp uses malleable iron with a hot-dip galvanized finish to resist weathering and provide long service life in non-hazardous environments. It carries UL certifications for rigid-IMC applications in the US and Canada, and its ordinary/non-hazardous location classification keeps installation straightforward in commercial and light industrial settings. By selecting this component, electrical teams benefit from reliable performance, reduced maintenance, and smoother installations, while aligning with code requirements. The 2-1/2 inch trade size complements common conduit layouts and supports consistent, scalable infrastructure.

FAQs
The 516 HDG clamp is specified for 2-1/2 inch trade size rigid/IMC conduit. It is designed to secure both rigid and IMC conduits, providing a reliable mounting point for lighting and electrical systems in ordinary locations. When planning installations, verify conduit dimensions and supported supports to ensure a precise fit and code compliance.
Yes, the 516 HDG clamp carries UL certification for rigid-IMC conduit hardware in both the United States and Canada, classified for ordinary locations. This helps streamline approvals during inspections and ensures alignment with standard electrical codes for commercial and light industrial projects.
Yes. The clamp uses malleable iron with a hot dip galvanized finish, which provides robust corrosion resistance suitable for many outdoor and damp location installations. Always confirm the specific exposure conditions and applicable codes to ensure ongoing reliability in harsh environments.
Plan for standard 2-1/2 inch conduit layouts and compatible supports to minimize field modification. The hot dip galvanized finish and malleable iron construction reduce rework due to corrosion or deformation, while UL-listed status supports quick approvals. Use with standard mounting hardware to speed up installation and maintain alignment across runs.
Choosing the 516 HDG delivers longer service life due to corrosion resistance, fewer maintenance events, and simpler inspections thanks to UL listing. It also supports scalable, repeatable installations with a common conduit size, reducing procurement complexity and labor costs for ongoing projects in commercial and light industrial facilities.
