The Simpson 1" Gas-Actuated Conduit Clip Assembly is a preassembled MEP fastener engineered by Simpson to secure conduit directly to concrete quickly and reliably. The clip and smooth-shank pin arrive ready to load into a compatible gas-actuated tool, streamlining high-volume mechanical, electrical, and plumbing installations where speed and consistency matter most.

Key Features

• Preassembled clip-and-pin unit - arrives ready to use straight out of the box, eliminating on-site assembly steps and keeping crews moving on high-volume MEP runs.
• Accommodates 1/2", 3/4", or 1" conduit - a single clip handles multiple common conduit sizes, reducing the number of SKUs a crew needs to stock on the job.
• 0.059"-thick conduit clip construction - provides durable, consistent holding power that stands up to the demands of commercial and industrial MEP installations.
• Compatible with gas-actuated and powder-actuated tools - works with gas-actuated concrete nailer tools for standard concrete applications and with common powder-actuated tools when fastening into structural steel or extra-hard concrete, giving installers flexibility across substrates.
• Smooth-shank pin design - delivers reliable penetration and seating into concrete, ensuring a secure, low-profile fastening result every time.

Why This Product

• Built for high-volume MEP work - the preassembled format means less time handling individual components and more time driving fasteners, making this clip a practical choice for conduit installations at scale.
• Versatile across substrates and conduit sizes - one assembly handles 1/2", 3/4", and 1" conduit on standard concrete as well as structural steel and extra-hard concrete when paired with a powder-actuated tool, reducing the need to switch products mid-job.
• Trusted Simpson engineering - designed and manufactured by Simpson, a brand with a well-established track record in structural and MEP fastening, so contractors can specify with confidence.
• Tool compatibility that fits existing workflows - designed for use with the G3 and GCN-MEPMAGKT tools, this assembly integrates into setups many MEP crews already have on hand, avoiding additional tool investment for most applications.
