nVent CADDY ERC 12312P 3/4" Conduit & Purlin Clip

nVent CADDY ERC 12312P 3/4" Conduit & Purlin Clip

The nVent CADDY ERC 12312P is a 3/4" conduit & purlin clip engineered to combine two mounting functions into a single fitting. Rather than requiring separate hardware for conduit support and purlin attachment, this fitting mounts 3/4" conduit directly to structural steel purlins in one step, cutting down on the number of individual parts an electrical contractor has to stock, sort, and install. It is built for electricians working on metal building and pre-engineered structural steel projects — the kind of construction where conduit routinely has to be run along purlin and girt framing rather than through wood or masonry — and it is designed to give that installation a fast, dependable, single-fitting solution instead of a field-improvised combination of a conduit clamp and a separate purlin clip.

Key Features

• Trade Size: 3/4" sizing for compatibility with 3/4" conduit runs.
• Dual-Purpose Design: Combines conduit clip and purlin clip functions in a single fitting, reducing the number of separate mounting parts needed on the job and simplifying the parts list on structural steel projects.
• Purlin Mounting: Attaches directly to steel purlin and girt framing commonly found in metal building and pre-engineered structural construction, without requiring an additional bracket.
• Simplified Installation: A single combination clip speeds up conduit support work compared to assembling multiple separate mounting components, saving time on repetitive structural steel conduit runs.
• Job-Site Efficiency: Fewer discrete parts to carry, sort, and install means less time spent staging hardware and more time spent running conduit.
• nVent CADDY Engineered Fitting: Purpose-built by nVent CADDY for professional electrical installation on structural steel framing, rather than adapted from a generic clamp.

Why nVent CADDY?

nVent CADDY builds mounting and support fittings engineered for the realities of structural steel and metal building installations, where conduit has to attach to purlins and girts rather than conventional framing. The ERC 12312P's combination conduit-and-purlin design reflects that focus: instead of asking a contractor to piece together a conduit clamp and a separate purlin clip on site, it delivers both functions in one purpose-built fitting. For electricians working metal building and pre-engineered steel projects, that means fewer parts to manage and a more consistent, code-compliant installation from run to run.
