Temporary Plugs

Cal Am’s Poly-Pull brand temporary duct plugs are designed for the interim sealing of standard duct, bell-ends and terminators from the damaging and expensive effects of weather, job site debris and animal incursion.

Available in 11 sizes ranging from one-half to six inches, the Poly-Pull Plug is molded from the highest grades of virgin Low Density Polyethylene (LDPE), a tough, high-impact and chemically inert resin that has near-zero moisture absorption properties. LDPE is resistant to ultraviolet light, ozone and is capable of withstanding extreme fluctuations in temperature.

While seemingly simple in concept, the Poly-Pull Plug has many design features making it an effective, efficient and economical means for the sealing of your conduit lines. A long-run tapered design allows for easy and quick insertion into your empty duct while a concentric set of scalloped ridges on the outside wall of the plug ensures a tight seal and prevents accidental dislodging of the plug. At the base of the Poly-Pull, is a sturdy, extended lip that allows a firm grip for easy removal of the plug. All Poly-Pull Plugs come with a molded-in rope tie for securing a line within the conduit.
