Metal Stud Wire Insulators 

When installing cables and pipes in metal studs, metal stud insulators are a smart, safe addition to the project. Universal Stud Insulators provide code-mandated 360° protection for cable runs through increasingly popular metal studs, where sharp hole edges could otherwise gouge plastic or rubber-jacketed electric, communications or network cable. The smooth, hang-free surface eases pulls, while the design accommodates any shape pre-punched hole or standard field-punched holes. Meets UL and CSA requirements.
