Foam Carrier · 3-1/2 in Conduit · For Vacuum or Blower Line Pulling · IDEAL 31-324
What this product is for
The IDEAL 31-324 foam carrier is a conduit cleaning and line-moving accessory sized for 3-1/2 in conduit. It attaches to a suitable line and travels through the raceway as a piston to help clear water, dust, and loose debris before cable installation.
Use for
- Cleaning 3-1/2 in conduit before pulling conductors
- Moving a pull string with a vacuum or blower system
- Checking that a conduit run is open before wire installation
- Electrical, commercial, industrial, and service work
Avoid for
- Conduit sizes other than 3-1/2 in
- Removing hardened blockages or obstructions that require mechanical cleaning
- Applications where a reusable mandrel, brush, or specialty swab is required
Best for
Electricians and contractors preparing larger conduit runs for pull string installation or pre-pull cleaning. This style of foam carrier is commonly used where a lightweight piston is needed to travel through the conduit with air movement from a vacuum or blower.
Installed in
Used in conduit systems rather than permanently installed equipment. Manufacturer family information indicates IDEAL foam carriers are used with rigid, EMT, IMC, PVC, and flexible conduit when matched to the correct trade size.
Why this product exists
Before pulling wire, contractors often need to remove moisture and loose debris and establish a pull line. This foam carrier provides a simple way to move through the conduit and help prepare the raceway for a smoother pull.
Typical guidance only: using a foam carrier before the main pull can help reduce avoidable snags, but actual performance depends on conduit condition, bends, debris level, and local installation practice.
Compared with similar products
Compared with smaller foam carriers, the 31-324 is sized specifically for 3-1/2 in conduit and should be selected by conduit trade size, not by cable size. Compared with brushes or more aggressive cleaning tools, a foam carrier is better suited to light debris, moisture clearing, and pull-line setup.
