Poly Pull Plug Brand Temporary Plugs – Cal Am’s Poly-Pull brand temporary duct plugs are designed for the interim sealing of standard duct and terminators from the damaging and expensive effects of weather, job site debris and animal incursion. Available in 11 sizes ranging from one to eight 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.
